The latest blog post, as is often the case, is by James Kennedy. Who has recently passed his PhD, so a massive congratulations to him! Enjoy! Pre-workout. An essential component to a good workout or an expensive placebo? Pre-workouts are ubiquitous in gym culture, especially on TikTok. For strength athletes, it's rare to see someone *not* using pre-workouts in the warm-up area before a big lift. So does it work, and if so, why? An essential component to a good workout or an expensive placebo? Look at the back of a pre-workout supplement, and you'll find a list of ingredients with scientific-sounding names, but what do they do? Do you need them? Are they dosed correctly? To find out, we googled and picked a generic-looking pre-workout from a significant player in the UK supplement market. The ingredients are listed below: The first step is to evaluate the ingredients (behind the fancy ® brand names). What is the ingredient meant to do, and is there evidence that it does this? Is it a WADA-approved supplement (a critical point for our IPF and IWF competitors!)? If the ingredient works, is it correctly dosed? Does the ingredient need to be 'loaded' (i.e. taken daily) to produce optimal results? Finally, when should this ingredient be taken to boost performance best? Ideally, at the end of this article, you will know what to look for in a pre-workout, what ingredients are necessary and how to take pre-workout supplements to best optimise your performance in the gym. Let's break it down! First up, Creatine Monohydrate, at 3500mg (3.5g). Creatine is well-researched and has a moderate boost in performance outcomes. It's safe, effective and cheap. Creatine is stored in the muscles and allows for rapid replenishment of adenosine triphosphate (ATP) in the muscle during intense exercises, allowing the muscle to continue to work at a higher intensity and thereby improving athletic performance. Creatine builds up in the muscles over time and requires daily supplementation to maintain high muscle creatine levels. Usually, the recommendation is for 3-5g, taken daily (supplement guide link). Within this supplement, the dosage is on the lower side. In addition, there is no specific time window to take creatine. The benefits from taking creatine accumulate from a daily intake and is likely best sourced from a creatine powder rather than a pre-workout (the same supplement company selling this pre-workout for £1.33 per serving is currently selling creatine monohydrate for £0.40 per 5g serving …. spend your money wisely guys!) Overall, it's good that an effective supplement like creatine is in this pre-workout. However, the dosage is low and buying creatine monohydrate and taking 5g daily is probably more cost-effective. The second ingredient is L-Citrulline (3g). Evidence shows that L-Citrulline improves nitric oxide metabolism, increasing muscle blood flow and enhancing the pump you get from training (https://examine.com/supplements/citrulline/#effect-matrix). Additionally, studies have shown a performance increase from L-Citrulline supplementation - as it improves reps to failure performance. This is where the good news ends, however. L-Citrulline is a second-tier supplement with the potential to move into the top tier (supplement article link) - meaning it's currently either understudied or underwhelming but with potential benefits worth exploring. Where L-Citruline is effective, the minimum dosage is 6g daily, with typical recommendations of 8-10g. This pre-workout provides half the dosage required to see a benefit. The second issue is timing. Pre-workout supplements are commonly taken immediately before or during warm-ups. L-Citrulline requires 1-2 hours to enter the bloodstream and reach the muscles. Within this supplement, the combination of dosage and recommended usage (30 minutes pre-workout) means you will get minimal benefit. An alternative option would be buying some L-Citrulline (roughly £10/100g) … although this works out at around £0.80 per serving. You could also not buy it; the magnitude of benefit from taking it is small, and it's doubtful you're missing out by not taking it. It's also worth remembering not to fall into the trap of thinking that taking the small doses present within this supplement will be enough to see a benefit and use that to justify buying the pre-workout! The third primary ingredient is Beta-Alanine, with 1.5g per serving. Beta-Alanine acts as an acid buffer in the body, preventing lactic acid build-up in the muscles, primarily when performing exercises in the lactic-aerobic zone (for example, a 400m sprint). For powerlifters, doing relatively low reps, you are almost exclusively using the anaerobic system with minimal lactic acid build-up; therefore Beta-Alanaine supplementation will likely be of minimal benefit to you. However, suppose you are a CrossFit athlete or bodybuilder. In that case, studies have shown an improvement in reps to failure in the 10-15 rep range (Effects of β-alanine supplementation on exercise performance: a meta-analysis - PubMed). Like creatine, the benefits of taking Beta-Alanine come from the build-up of Alanine in the muscles. Unfortunately, whilst the ingredient is beneficial, it is underdosed again within this supplement. It would be best if you took a larger daily dose to benefit from Alanine supplementation - similar to L-Citrulline, meaning the amount of Alanine in this supplement is too low for you to help your performance. The Nootropics The following two ingredients, L-Tyrosine and L-Theanine, belong to a group of substances called nootropics. Nootropics, as a group, improve cognitive function and mental performance. Typically, L-Tyrosine and L-Theanine are used to offset the stress and anxiety associated with higher dose caffeine consumption, thus allowing you to benefit from the caffeine (improved focus and alertness) without suffering the downsides. The pre-workout contains a well-dosed amount of both substances, which will enhance the benefit of caffeine. Taurine Dosed here at 0.5g, Taurine is an amino acid with diverse bodily functions. It is most relevant to energy metabolism and its anti-inflammatory properties here. Whilst the extract mechanisms are unclear, Taurine does increase fat burning for fuel and improve mitochondrial function (https://pubmed.ncbi.nlm.nih.gov/34039357/). In addition, it is beneficial in treating inflammatory diseases, such as arthritis (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5933890/). In studies, the effects of taking Taurine are relatively minor to non-existent with doses of ~3g. Sadly, as this ingredient works, it is massively underdosed in this supplement. Caffeine Caffeine is an effective stimulant - as anyone who's tried to function before having a morning cup of tea or coffee can test - which occurs naturally in tea and coffee. Alongside the obvious mental benefits, it also improves strength and endurance. The literature, and probably everyone's personal experience reading this, is that caffeine is an effective and relatively safe performance enhancer and should be used in pre-workouts. The dosage present in this pre-workout is reasonable - 200mg - broadly the same as a double espresso. At higher doses, caffeine can interfere with sleep - hampering recovery. The sleep interference effect is especially pertinent if you take caffeine within ~8 hours of trying to go to sleep. So, suppose you're tired before a workout in the evening or afternoon. In that case, there are better options than reaching for a pre-workout. Get through the workout, get some sleep, and recover; caffeine will temporarily mask the problem without addressing the cause. The Vitamins The next group of ingredients are the vitamins - Vitamin C, B6,9 and 12. Vitamin C does (slightly) reduce muscle damage (https://pubmed.ncbi.nlm.nih.gov/15024666/); however, that study used a 200mg dose to achieve a small impact. In what should not be a surprise, Vitamin C is underdosed in this pre-workout, with only 80mg present. Vitamins B6,9 and 12 are common ingredients of pre-workouts and energy drinks, included to improve energy metabolism. The theory goes that they help you metabolise more energy, making you feel more energetic. Sadly, this is untrue. If you have a Vitamin B deficiency, you will likely have low energy, as a Vitamin B deficiency stops your body from breaking down food, leading to low energy levels and potentially anaemia. If you don't have a vitamin B deficiency - your body will filter the excess out into your urine, making this ingredient a waste of time. The Proprietary Blend - EnXtra EnXtra is a proprietary extract of the Alpinia galanga plant, sometimes known as Blue Ginger. This plant is part of the ginger family and is used as a herb and spice in South Asian and Arabic cuisine and traditional medicine. Its use in traditional medicine has led to it being investigated for various properties - most pertinently as a stimulant. A study has shown that EnXtra can improve alertness and limit or prevent post-caffeine energy slumps when consumed with caffeine (https://www.tandfonline.com/doi/abs/10.1080/07315724.2017.1342576). The caveat? This study was funded by the company that sells EnXtra. This doesn't make it wrong, but it is context! This ingredient is harmless and potentially beneficial, although its purpose overlaps significantly with the well-researched and non-proprietary nootropics within the pre-workout. Conclusions / Discussion This pre-workout does contain practical, well-studied and effective ingredients. However, it underdoses most of them, and the benefits of these ingredients come from long-term, daily usage - not 3 or 4 times a week before a workout. In addition, the performance-enhancing impact of these supplements is related to when you take them around the workout. With that in mind, let's learn how to use these ingredients to optimise your training. Firstly, creatine monohydrate and beta-alanine. Both of these supplements build up in the body over time - 5-10g of creatine and beta-alanine should be taken whenever is convenient throughout the day. The next group of supplements are time dependent. L-Citrulline needs to be taken 1-2 hours before the workout to maximise the benefits of using the supplement and needs to be dosed effectively to guarantee to achieve this. Ideally, you would take a 6-8g dose around 90 minutes before training. Around the same time, you should take the nootropics and Taurine, as these can take up to 2 hours to begin working. Moving closer to the workout is where you should start to take the stimulants. It would help if you consumed caffeine 15-30 minutes before starting the activity to give you the ergogenic benefits but prevent the caffeine crash from happening mid-workout. This outline of how much and when you should take these supplements shows the fallacy of cramming all these ingredients into one super pre-workout. If you took this pre-workout and began drinking it on the way to the gym, the only ingredient which would benefit you in the workout is the caffeine. Besides being underdosed, the other ingredients would only help you at the end of the workout or on the journey home. Overall, this is an important point. The ingredients in this pre-workout are fine if underdosed. But taking them in one go at the start of the workout likely inhibits the benefits you should feel from taking them. If you are determined to use these ingredients, follow the protocol outlined in this article and ensure you hit the effective dosage outlined. However, if that sounds like too much effort for minimal reward, take creatine monohydrate every morning in your water and have a cup of coffee before your workout.

The latest blog post is written by Coach Beá, and it's about a very important topic - Cutting for Competition. If you've been coached by me you will know that I feel quite strongly about cutting, or rather not cutting, for competition - particularly in your early competitions. I'll let Beá explain the rest. The ultimate debate of powerlifting To cut or not to cut? Most powerlifting coaches would tell you, likely as a straight answer, don’t. But then whenever we hear the success stories from the elites & champions, there’s always a mention of some sort of ‘making weight’, ‘water cut’, ‘fasting’ and other stuff. So why are we, coaches, so against the idea of cutting body weight when it always seems to be part of the winning tool kit. The explanation is that famous phrase ‘it depends.’ But rest assured, in this post I will answer this question. Firstly, what do we mean by cutting/making weight? In powerlifting, in order to make sure the competition is fair for everyone, contestants are divided into age and bodyweight categories. We use Wilks, GL Points or Dots to calculate the score for each lifter based on their bodyweight, total and other factors, the highest score wins. The common understanding, unfortunately, is misleading as the majority of beginners still believe they have to aim for squeezing themselves into the lower body weight category and try to max out the highest total they can possibly hit there. Now...does this in any way, shape or form, resemble a ‘growth mindset’? For instance, a male lifter who weighs 87kg, which is in the middle between the two body weight categories, 83kg & 93kg. This athlete can make the decisions to lose 5kg and cut their strength alongside their size, increase stress levels or sit still and comfortable and take advantage of extra fuel and enhanced recovery rate and maybe even put on a kilo or two knowing it still will be absolutely fine for the comp. When people cut calories and body size that also means cutting potential gains: - gains for heavier lifts, recovery and overall, a heavier total on meet day. Novice lifters, who are still progressing very fast in technique and/or strength, should never worry about cutting weight for this reason. You might win the upcoming competition and take a gold medal home. But you also hindered your potential development by limiting the calorie intake and accumulating higher levels of fatigue (pushing your maxes with decreasing body weight). This means that whilst you got a gold at a smaller comp the one you qualified for will be harder now due to the aforementioned factors. Whilst you’re struggling, your competition is already back in training enjoying calorie surplus and just being an absolute unit. ‘If I wanna become like the elites, I must do what they do..’ Ask anyone of the current world champs, if they’ve done any of the ‘fancy stuff’ when they competed at their first comp? -No, they did not. Elite Powerlifters, the ones who've been in the sport for over 5 years, are not making progress as quickly anymore. They are pushing their biological limitations, and their recovery rate has slowed down over the years. They have to really push their limits and are likely to make a fraction of an increase in total compared to that of a beginner. They have to use every little trick left in the magic hat if they want to get a higher/better score and they’re provided with all the professional aid in order to get the required result. Most recent example, Evie Corrigan (52kg- ), winner of Sheffield, the biggest IPF event of the history,. When Evie started the comp prep she was a 57kg- lifter but was comfortably sitting at 54kg, for her losing 2kg made little to no alteration to strength levels and it also meant a higher chance to get close to hit the highest % over the current world records. For her cut she has assistance from nutritional coach as well and her powerlifting coach. They went through every scenario and drew up every possibility for both 52kg & 57kg category just to make sure it’s indeed a worthy call to make with everything’s at stake. Social Media Social media plays a huge part in overwhelming and distracting rookie lifters from what priority to focus on when prepping for meet day. To clarify for the first 3-5 competitions the biggest goal for any lifter should be to make every attempt, get 9/9 and gain competition experience. What do we mean by ‘experience’ isn’t just being there, it means answering the following;
One dangerous aspect of cutting weight for competition is the impact of dehydration. Which will result in a lack of minerals as well as a lack of energy. This is due to the absence of sugars which the body would naturally need for survival. This puts the athlete in a really unsustainable condition if not monitored, or controlled adequately. The least people would experience who are dehydrated during comp is occasional cramping up but this can quickly turn into total passing out and other, even more severe long lasting damage to the metabolism and to the musculature. It’s crucial that whoever decides to undergo this kind of drastic act, create a sustainable - realistic plan and follow it through. There are different weigh in times for different body categories throughout the day, so not eating all morning for your 2pm weigh in would be a shot-in-the-foot move. This is a whole other science just like powerlifting itself and so it shouldn’t be taken lightly. There’s many useful resources for game day planning, which would also talk about the different approaches on how people can execute weight cuts and still enhance their comp performance. And most importantly, athletes, immediately after they successfully weighed in, are to hurry re-hydrating and re-fuelling within the allocated 2 hours prior to the lift off. Without a well laid out plan, you not only make your competition day harder than necessary, but you also risk potentially bombing out due to poor performance. So to answer this longing question: Cut or not to cut? It depends, are you… A, a beginner lifter who is still developing in physique and gaining experience in competing. B, a veteran lifter, who’s been competing for years and likely to be at their biological threshold for strength levels and would need a more dramatic approach to increase total? If you admit to being A, it’s great because the longer you stay in a rookie mindset, then the more potential you will still have to become a freaking beast. If you’re B, with your experience you are likely to have professional powerlifters in your social circle who are experienced enough, and can guide you on this topic on a qualified level.

The latest article from James Kennedy for you here. It's all about Fat Burning supplements - should you buy them and are they worth it? Fat burners and weight loss pills are nutritional supplements which *claim* to increase fat metabolism and energy expenditure, speeding up fat loss and allowing people to lose weight quicker. They are popular supplements, with over $2 billion spent annually in the US alone on fat burners and weight loss supplements (1). In strength (powerlifting and weightlifting) and physique (bodybuilding) sports, fat burners are commonly used to help athletes manage weight loss and reach lower weight classes whilst maintaining as much lean body mass and muscle as possible. Sounds great right? Well, let’s go back to 2011. The Manchester City football player, Kolo Toure, was suspended for six months after failing a drug test which he blamed on taking his wife’s weight loss pills which contained a banned substance unbeknownst to him or his wife (2). Does this still occur? What’s actually in a fat burner? Do they work or are they just a way of supplement companies getting even more of your money? To find out, I decided to break down every listed ingredient in the fat burner which appeared at the top of the Google search results. I then searched the internet and the scientific literature for the supplement’s ingredients, finding what the ingredient is claimed to do, what the evidence supports and whether the ingredient would be effective in the supplement. The ingredients of the first fat burner that popped up on Google. These are the listed ingredients for the fat burner that turned up on Google - the ingredient list is pretty typical for a pre-workout. The website advises you to take three tablets spaced evenly throughout the day, which will provide you with ‘an impressive array of 9 potently dosed ingredients’ which will wake you up, keep you alert and keep blood sugar levels normal all whilst boosting metabolism, burning fat and reducing appetite. Let’s evaluate these claims… Citrus Aurantium The first listed ingredient is Citrus Aurantium, which is more commonly known as bitter orange. Bitter orange contains p-synephrine, a molecule similar to the banned stimulant ephedrine, which has been researched and marketed as a product which can increase your metabolic rate and alertness, whilst reducing appetite, anxiety, blood pressure and heart rate (3,4). However, the scientific literature has found no to negligible impact of supplementing bitter orange on these outcomes - though it may have a small positive impact on digestion and blood circulation (4). Overall, bitter orange has not been shown to be an effective stimulant, with its popularity in supplements primarily due to the similarity between p-synephrine and the banned, highly effective stimulant, ephedrine. Whilst p-synephrine is legal in World Anti-Doping Agency (WADA ) sanctioned competitions, it was added to their watch list in 2019 to monitor its misuse in sports as a fat-loss supplement (5). Overall, Bitter Orange isn’t an effective fat burner or stimulant Green Tea Extract The second listed ingredient in this product is Green Tea Extract. Green tea extract should contain green tea catechins, a group of four molecules with a range of health benefits (6), with the most potent being EGCG (7). Green tea or green tea extract does have benefits as a ‘fat-burner’; it is effective in reducing body fat (8) and increasing fat oxidation - the percentage of calories from burning fatty acids (9). However, these effects are small and unreliable, with caffeine sensitivity being key to getting these benefits. Importantly, these benefits can all be achieved by just drinking green tea. Just 0.02p per serving in Aldi! You may assume that the green tea extract would be more concentrated, with a higher proportion of catechins, especially EGCG, which would increase the efficacy of the supplement. You would be wrong. A typical green tea extract is about 50% EGCG, corresponding to 50mg of EGCG per tablet in this supplement. Depending on the species of tea and brew time, a single cup of green tea can contain 100-200mg of catechins and 50-100mg of EGCG (10). Furthermore, the fat-burning properties of green tea extracts are dose-dependent, with significant effects only shown at doses of 400mg+ of EGCG per day. The fat burner we are investigating today most likely provides you with 150mg of EGCG per day, or about the equivalent of 2-4 cups of green tea, and significantly below the dosage required to have significant effects on fat loss or fat oxidation. Caffeine Caffeine is an effective stimulant, found naturally in tea and coffee. Whilst caffeine is a stimulant and nootropic, it has also been found to improve physical strength (11) and endurance (12). Furthermore, habitual caffeine use is linked to a reduction in the risk of a range of diseases - including Alzheimer's and cirrhosis. At high total daily doses, however, caffeine can interfere with sleep patterns - often leading to the caffeine spiral, whereby you have too much caffeine, can’t sleep, then use more caffeine the next day to increase alertness and so on. Habitual (i.e. daily) caffeine consumption leads to a ‘hard tolerance’, where more caffeine won’t overcome the tolerance, however, the sleep interference side-effect/benefit appears to be independent of an individual's caffeine tolerance. Within this fat burner supplement, caffeine is appropriately dosed. A 100mg per tablet of caffeine is broadly equivalent to the caffeine content of a cup of filter coffee or two cups of tea. Overall, the caffeine in this fat burner is probably effective - it’s a proven stimulant and performance enhancer and it’s dosed effectively. However, if you’re drinking 2-3 cups of coffee and/or tea a day, the additional benefit of the caffeine within this supplement is probably negligible. The Aminos The next two ingredients in the fat burner are L-Tyrosine and L-Theanine, both amino acids. L-Tyrosine is an amino acid used as a precursor for dopamine and norepinephrine, two catecholamines depleted in stressful situations. Supplementing with L-Tyrosine can help restore catecholamines levels in the brain, reducing stress-induced reductions in mental performance (13,14). Typically, people take 500mg - 2000mg of L-Tyrosine before an acute stress event (a workout or game), to improve mental performance during exercise. When studied, doses to achieve anti-stress effects found a range of 100-150mg/kg taken around an hour before exercise (13). Our fat burner supplement offers a relatively paltry 200mg spread across three doses taken throughout the day - severely limiting the improved cognition effects of taking L-Tyrosine. L-Theanine is a non-protein amino acid, found in tea. L-Theanine makes you feel relaxed without making you drowsy. When taken with caffeine, it may help enhance the cognitive effects of caffeine by offsetting the anxiety associated with caffeine consumption (15). It is present in tea, with 50mg per cup on average, and is typically dosed at around 100-200mg as a supplement. The fat burner supplement contains 150mg, spread into three doses, or about the equivalent of three cups of tea per day. Kola Nut Extract We now move on to the Kola Nut Extract. This supplement is relatively understudied, however, is commonly used in West Africa where it originates as a stimulant. Broadly, the reported health benefits of consuming the Kola nut or Kola nut extract align with caffeine consumption (16, 17). Whilst it is a popular ingredient of fat-burning supplements it has not been studied in this role and its efficacy is unknown. Chromium Chromium is an essential mineral consumed in the diet, typically found in grain and plays a role in insulin regulation. Chromium supplementation however had no reliable impact on insulin for people with normal or elevated chromium levels (18). Interestingly, there is some evidence that Chromium can help with managing food cravings whilst in a calorie deficit. Specifically, a single study found that supplementing with 1000mcg of Chromium led to a greater reduction in food intake vs a placebo group (19). This result was significant but needs further study to understand if this effect is replicable and why Chromium supplementation has this effect. The Spices The final ingredients within the fat burner are the spices - Cayenne Pepper and BioPerine. BioPerine is a black pepper extract and cayenne pepper is a type of chilli pepper, which will be in this supplement for its capsaicin content. Capsaicin is the molecule which makes foods spicy and causes the associated side effects. Why is this in a fat burner? Well, capsaicin is trumpeted as a substance which helps with weight or fat loss by boosting your metabolism, helping burn body fat and improve metabolic health. However, when studied, Capsaicin has been found to have ‘minimal potency’ in impacting fat loss or improving metabolic health (20). The presence of BioPerine - black pepper extract - will be due to its ability to increase the bio-availability of other substances, particularly spices, by inhibiting enzymes which attack other molecules. Bio-availability is basically how well a substance can be absorbed by the body; piperine is highly effective in increasing the bio-availability of other compounds consumed within a supplement (21,22). Conclusions So what’s in a fat burner? Mainly substances you can get in tea and coffee, which have a minimal impact on fat loss and metabolic health and are underdosed. If you want to lose weight and improve body composition, find a good coach (link) and eat in a sustained calorie deficit whilst following a well-structured training plan (link). Don’t waste your money on magic pills and shortcuts: supplement companies are just trying to scam you out of your hard-earned money and waste your time. Don’t let them.

Vegan and vegetarian diets are becoming increasingly popular, due to the ethical and environmental impact of eating animal produce, as well as the health benefits of veganism. However, bro-science has argued for years that the only way to get jacked and ripped is to eat steak, with a side of eggs and a glass of milk 3-6 times a day, making a lot of strength athletes nervous about trying a vegetarian diet, despite the purported health benefits. In this article we’ll explore the health benefits of a vegan or vegetarian diet and whether strength athletes can eat a vegetarian diet and still maximise their training. Firstly, definitions. There are several types of vegetarian diets - all vegetarian diets involve some restriction on the amount of meat and animal produce consumed within the diet. The five main types of vegetarianism are, in order of flexibility:
Longevity It’s commonly claimed that vegetarians live longer than omnivores (1). This reinforces the notion that vegans or vegetarian diets are healthier - if a vegan diet is healthier, we would expect vegans to live longer. It’s true that vegan diets are associated with a range of health benefits, including lowering obesity rates, type 2 diabetes and heart disease - which are all common diseases increasing mortality rates (2). However, it’s not quite that simple. Plant based diets (i.e. flexitarian through to vegan diets) which rely on nutritious food lower your risk of heart disease by 25%. In contrast, plant based diets which are high in processed foods increase the risk of coronary heart disease by 32%! (3). Further, a recent meta-analysis (4) between vegetarians and *comparable* non-vegetarians have similar all cause mortality, with vegetarians having lower mortality rates from pancreatic and lymphatic cancers and meat-eaters having lower mortality rates from respiratory disease and all-cause mortality rates (the authors suggest more research is needed into why specific causes of death differ between the groups - though this is unnecessary. Meat eaters have lower all cause mortality because they’re less annoying than vegans, therefore they get beat to death less). The longevity impacts of a vegan diet are overstated because of a series of confounding factors. Generally, vegans or vegetarians are more health conscious than the general population, as well as being higher educated, more physically active, sleeping more and smoking and drinking less (5). These confounding factors mean that the health benefits that vegetarians enjoy could be a result of the lifestyle, with the studies focusing on comparison between vegetarians and comparable meat-eaters suggesting that the health benefits are actually from the lifestyle that vegetarians adopt, rather than the diet. So, no, a vegan or vegetarian diet will not make you live longer if you are a generally healthy person. But does it have any health benefits? Inflammation Inflammation, or chronic inflammation, has started to be blamed for a lot of disease over the past half-decade or so (6,7). Whilst some inflammation is a good thing, elevated levels of inflammation for long periods of time (chronic inflammation) can cause health issues. It has been found that adopting a vegetarian diet over an extended period (over 2 years) does reduce inflammation, however, no study has been done comparing between vegetarians and comparable non-vegetarians (8). Once again, the chronic inflammation reduction seen in vegetarians may just be a result of the lifestyle choices vegetarians make. Weight loss Yes for general population - probably not for athletes Vegan and vegetarian diets do cause more weight loss than non-vegetarian diets for the general population (9). However, no data exists on the body composition lost (fat, muscle or water), or on the impact on weight loss for vegan strength athletes. Speculatively - this is not based on any studies, just what I *think* might happen - it may be difficult to eat enough protein as a strength athlete whilst losing weight. When trying to lose weight, we should be aiming to eat around 2.2g/kg of protein. This could be challenging to achieve in a vegan diet, as most vegan protein sources also contain high levels of carbohydrates. Consequently, eating a vegan diet when cutting could make it challenging to retain muscle mass. Eating a lacto-ovo or lacto vegetarian diet may make it easier to hit their protein targets without going over their calorie or carbohydrate targets. Having established that the health benefits of vegan and vegetarian diets are overstated, with comparable people who eat omnivorous diets seeing similar health outcomes, the next step is to see if there are any impacts on athletic performance from eating vegan or vegetarian diets. Advice for athletes Athletic performance in general A systematic literature review comparing the athletic performance of vegetarians and omnivores found that, over eight short term studies (12 weeks in length) there was no difference in athletic performance between vegetarians and non-vegetarians (10). Theoretically, there could be long-term impacts on health and performance from eating a vegan diet but no empirical studies on athletes has been done (11). The impact, or potential impact, of these shortcomings can be alleviated by careful food and supplement selection by vegan athletes. The first consideration is protein. Generally, protein from plants is less well digested and lacks essential amino acids which are essential in building muscle. Whilst lacto-ovo vegetarians generally will get enough of these amino acids from dairy and eggs, vegans should make sure they eat a source of lysine (beans, legumes), leucine (soy beans and lentils) and other BCAA rich foods (seeds, tree nuts and chickpeas. To make sure that vegans are getting enough digestible protein to support muscle growth, they should also consider boosting protein intake to around 2.2g/kg. **what about whey?** **Whey protein is obviously not vegan, as it is made from dairy. However, Whey is a waste product from cheese production, with 10L of milk making 1kg of cheese and 9L of whey (think of the nursery rhyme, separating curds and whey). Whey is also an incredible environmental toxin, thought to be 175 times more toxic than human sewage (12). For environmental vegans, whey could be used as a sustainable option. Since whey protein is a by-product of the dairy industry, the environmental impact of whey is itself, small. The environmental impact of whey protein is really low; the carbon and pollution emissions occur during the cheese production process. For vegans, this may mean a cheap, higher quality protein source could be utilised.** The second potential issue to address is fats. Vegans eat less fat in general which can be linked to lower testosterone levels (note - *vegans do not have lower testosterone vs omnivores*) , so this may be a non-issue. Vegans also eat less omega-3 fatty acids, which are important for the immune system, growth and development. However, the solution is pretty simple. Eat avocados, nuts and seeds and take a micro algae or omega 3 supplement. There isn’t overwhelming evidence that any of the potential side effects of eating a vegan diet (i.e. the most restrictive vegetarian diet) has a negative impact due to low fat content. It theoretically could however, so make sure you’re still getting enough dietary fat from oil, avocado, nuts and seeds as well as taking an omega-3 supplement. Finally, we get onto micro-nutrition. Whilst this may seem counterintuitive as vegetarian diets are generally higher in fruit and vegetables, they are deficient in a few key vitamins and minerals. First up is vitamin B12. Vitamin B12 is an essential mineral used in the nervous system, blood and DNA, which primarily enters the diet through animal and dairy products. A deficiency in vitamin B12 causes tiredness and lethargy in the short term and can lead to anaemia and central nervous system damage in the long term. Vegans and vegetarians are therefore commonly advised to take about 6 micrograms of vitamin B12 supplementation a day. THIS IS NOT MEDICAL ADVICE but a can of monster energy has 13 micrograms of vitamin B12 … just saying. The other major micronutrient which can be difficult for vegans to get into their diets is Calcium. Calcium is important for bone and muscle health, with vegans and vegetarians consuming less than non-vegetarians. This one does have evidence of it being a problem, with vegans having an increased risk of bone fractures and lower bone mineral density (11). The primary source of calcium in mixed diets is dairy - vegans are limited to high calcium vegetables (broccoli and kale) or calcium fortified foods. Summary So, can a vegetarian diet ever be appropriate for a strength athlete? Easily. If you’re a strength athlete, eating a flexitarian diet (i.e. not eating meat or fish 2-4 days a week), will have no noticeable impact on performance or physique goals. Pesco-vegetarianism and Lacto-ovo vegetarianism are also vegetarian diets which would reduce the ethical and environmental impact of your diet without hindering strength training outcomes. The most restrictive vegetarian diets - veganism - could, potentially, have some long-term drawbacks. These drawbacks can easily be addressed however by supplementing the diet with vitamin B12 and calcium, as well as some vegan friendly omega-3 sources. The one case where it may be difficult to maintain a vegan diet is if you are attempting to get very lean - sub 10% body fat. In this scenario, you are trying to reduce body weight and maximise muscle mass retention. Most vegan protein sources are higher in calories than their non-vegan alternatives, which could make managing a cut difficult. Overall, there is no reason why eating a vegetarian diet would have a negative impact on your strength and physique goals. If you're interested, start by going flexitarian and slowly progress through pesco-vegetarian and lacto-ovo vegetarian diets and see how it goes!!! References

What to Know - Word Count - 1200 words. Time to Read - 4 minutes ish. In Part 1 of our diet setup guide, we outlined the 5 components of a diet: 1. Calories. Calories provide the fundamental control on whether weight is gained or lost. If you eat more calories than you burn, you will gain weight. If you eat less calories than you burn, then you will lose weight 2. Macros. Macros (Protein, Carbohydrates and Fats), are important in helping you reach physique goals more quickly than if you just focus on calories alone. 3. Micronutrients. Micronutrients aren’t massively important in attaining physique goals - however long-term deficiencies will impact your health and ability to train and recover. 4. Meal timing/frequency. Meal timing and frequency is a topic which generates a lot of discussion and catchy slogans but it doesn’t really matter, if you are hitting your calorie and macro targets. These will be discussed in more detail in a future article. 5. Supplements. Supplements are the smallest part of the puzzle - I wrote about supplements in a previous article (link here). For now, all we need to know is that supplements, supplement your diet and help you reach your calorie and macro targets. The first article focused on the two most important factors in determining diet success - Calories and Macros. Part 2 is focusing on the other three components of diet; micronutrients, meal timing and frequency and supplements. Whilst these are less important than calories and macronutrients to determining success, they do play a role in your long term health and diet success. Micronutrients Micronutrients are nutrients required in the diet in small amounts for optimal health and performance. Whereas macronutrients are measured in grams, micronutrients are usally measured in the diet in miligrams. In the short term they aren’t super important, but long term micronutrient deficiencies cause serious health issues and will impact your ability to train effectively. Micronutrients can be divided into two groups - vitamins and minerals. Minerals are non-organic (e.g. Iron, Zinc, Sodium etc.) whereas vitamins are organic. Vitamins are further subdivided into water-soluble and fat-soluble. Water soluble vitamins (e.g. Vitamin C) pass through the body in urine (which is why your pee turns a bright colour when you take a vitamin C tablet). Fat soluble vitamins are absorbed in the stomach and build up in the body. This means that deficits and surpluses build up in the body over time and can’t be quickly corrected. How do I make sure I get enough micronutrients? Tracking your micronutrition is not recommended unless you have a specific micronutrient deficiency that needs addressing. For most people the micronutrients contained in meat (B-minerals), dairy (calcium, zinc and vitamin A) and starchy carbohydrates (Zinc, magnesium and vitamin B6) will be present in the diet in ample quantities. The micronutrients present in fish (primarily omega-3 fatty acids) and fruits and vegetables (Vitamin A, C, D, E and others) are more likely to be under-represented in the diet.. The simplest way to make sure you’re covering all the bases in terms of micronutrition is to eat a varied diet, with 2 meals of fish a week and plenty of fruit and vegetables each day. Eric Helms gives the following guidelines for his bodybuilding competitors on specific quantities of fruit and veg per day: Calories. Cups of fruit & vegetables / day. 1200 - 2000. 2 cups each. 2000 - 3000. 3 cups each. 3000 - 4000 4 cups each. The reason that these recommendations decrease with calorie intake is twofold:
Can i just take a multivitamin and not eat fruit and vegetables? No. To quote Alan Aragon: ‘a poor diet with a muti(vitamin) is still a poor diet’. Eating plenty of fruit and vegetables is essential for optimising health and performance. A multivitamin is a good insurance policy - if there are gaps in your micronutrient intake from your diet, then the multivitamin will help cover them. However, they will not provide you with the total health benefits that eating a variety of fruit and vegetables will. Nutrient Timing and Meal Frequency Nutrient timing and meal frequency is overrated. It certainly can have a small impact on body composition and help with diet adherence, particularly when cutting, but the overall success or failure of a diet will be controlled by calories and macronutrients. There is evidence that meal frequency (specifically intermittent fasting), does have health benefits but it’s debated as to whether these impacts are due to intermittent fasting or just caloric restriction and weight loss. For beginners, or those new to tracking calories and macros, simplicity is key. The best diet for you is the one you can stick to. To begin, there are three main considerations:
The number of meals you eat is related to how many calories you have to eat that day. If you are cutting, splitting those calories into 2-4 meals is probably best. If you’re bulking, eating 3-4 meals will work better - trying to cram a calorie surplus into two meals is probably going to be unpleasant. When you’re cutting, eating fewer meals can be psychologically beneficial because you can eat 2 normal meals and one smaller meal or even skip a meal. It is also important, especially when cutting, to space your meals around your training. If you’re training in a calorie deficit, making sure you are fueled properly around the workout is essential for getting the most out of your training that you can. Firstly, never train completely fasted. Even if you are training at 6am, take a protein shake to the gym with you and sip it throughout your workout (p.s. If you find protein shakes too milky to drink during a workout, try MyProtein’s clear whey - it’s excellent for intra-workout shakes). Once you have finished your workout, make sure you eat within two hours of finishing a session. Make sure you eat more in the post-workout meal than the pre-workout meal and try to split your macros evenly between the meals. Finally, breakfast. Skipping breakfast - or having a low calorie meal like a protein shake - can be helpful if you’re cutting. It makes calculating your calories and macros easier as you can just split them between two meals. Typically, people in a calorie deficit find it easier to skip breakfast and then eat two more or less normal meals. Supplements The final piece of the puzzle is supplements. These are supplements to the diet - not a magic bullet. Broadly, protein powder is a worthwhile investment as it can help you boost dietary protein without the addition of excess calories. Make sure your protein powder doesn’t contain a large amount of filler - a good powder will contain 18-20g protein per 25g scoop. There are a range of other supplements which can help your performance - link here - but they are non-essential to your dieting goals. Summary The keys to a successful diet are your calories and macros (link this to article 1). Your micronutrition, nutrient timing and meal frequency have a smaller impact on the overall success of a diet, but cause a huge amount of confusion. Fundamentally, eating 2-4 meals per day, with a varied diet including fruit and vegetables and using high quality protein powders and supplements to fill in the gaps will take care of your basic micro-nutritional and meal frequency needs.

Setting up a diet According to survey data from the US 41% of gym-goers attend the gym to lose weight and 38% go to look better (Source - https://www.statista.com/statistics/639169/reasons-behind-gym-exercise-in-us/ ) . Whilst exercising is a key component of improving your physique and losing weight, your diet is essential to help maximise both muscle growth and fat loss. Diet is a topic for which there is no end of bullshit on the internet. If you don’t get the fundamental parts of a diet sorted, then you will be wasting your time and money. This article will explain what the key components of a diet are, what you should focus on and how to get started with your diet whether you want to build muscle or lose fat. TL; DR
Nutritional Importance There are 5 components to a diet, in order of importance: 1. Calories. Calories provide the fundamental control on whether weight is gained or lost. If you eat more calories than you burn, you will gain weight. If you eat less calories than you burn, then you will lose weight 2. Macros. Macros (Protein, Carbohydrates and Fats), are important in helping you reach physique goals more quickly than if you just focus on calories alone 3. Micronutrients. Micronutrients aren’t massively important in attaining physique goals - however long-term deficiencies will impact your health and ability to train and recover. 4. Meal timing/frequency. Meal timing and frequency is a topic which generates a lot of discussion and catchy slogans but it doesn’t really matter, if you are hitting your calorie and macro targets. These will be discussed in more detail in a future article. 5. Supplements. Supplements are the smallest part of the puzzle - I wrote about supplements in a previous article (link here). For now, all we need to know is that supplements, supplement your diet and help you reach your calorie and macro targets. This article is primarily going to focus on the first two points; calories and macros with micronutrients, meal timing and frequency discussed in a subsequent article. Setting up your diet When setting up a diet - whether your goal is muscle gain, fat loss or to maximise sports performance - the most important thing is calorie balance. There are 3 main components to a diet: 1. Choosing appropriate fat loss or muscle gain targets based your current levels of body fat or training experience 2. Calculating your target energy intake 3. Calculating your macronutrient breakdown Most people want to lose fat or gain muscle, or ideally do both simultaneously. Your ability to gain muscle and lose fat at the same time decreases with body fat percentage and training experience. The less time you’ve been training and the higher body fat percentage you have, the easier it will be to gain muscle and lose fat at the same time. However, if you are a complete beginner to training, you may be better focused on just trying to gain muscle - your ‘noob gains’ will be much greater and training will be easier. When we are deciding about whether to lose or gain weight it is important to establish what our goals are. Should we try to gain muscle and add weight (bulk) or try to lose body fat (cut)? The first question to ask yourself is what your training goals are. Are you a powerlifter or strongman competitor who just wants to maximise the amount of weight you can lift? Are you a powerlifter looking to move up or down a weight class? Or are you a bodybuilder or fitness enthusiast who is looking to maximise your physique? Generally, if your body fat percentage is above 15% for a male athlete or above 25% for a female athlete, you can cut your body-fat levels down to 8-10% without losing much strength. For the powerlifters out there, if you are near the bottom of your current weight class and carrying higher levels of body fat, cutting to reach the weight class below may allow you to become highly competitive. For example, if you weigh 85kg and have 20% body fat and compete in the 90kg weight class, you could easily lose 5-8% body-fat and move down to the 82.5kg weight class without losing any strength. This will make you relatively stronger and more competitive in the lower weight class. If you are already fairly lean, below 8-12% body fat levels, deciding to bulk may be more appropriate. Once you have decided whether to bulk or cut, the next step is to calculate how many calories you should eat. Thankfully, there is a helpful tool available to do this (http://dannyleeonline.co.uk/macro-calculator.html). To use this tool, firstly weigh yourself and measure your body fat percentage. The two easiest ways to measure your body fat percentage at home are either the calliper method (https://www.myprotein.com/thezone/nutrition/how-to-use-skin-fold-calipers-measuring-body-fat-percentage/) or the tape measure method developed by the US Navy (https://rippedbody.com/how-calculate-body-fat-percentage/) Once you have these numbers, it’s possible to calculate your lean body mass (LBM). The next step is to establish your target LBM and target body-fat percentages. For those deciding to cut, you are aiming to maintain LBM and lose body-fat. Broadly, the following fat-loss targets are appropriate: Body Fat %. ->30. 20-30. 15-20. 12-15. 8-12. <8 Target fat loss/week - 1.1kg. 0.9kg. 0.7kg. 0.5kg. 0.3kg. 0.2kg (source: https://rippedbody.com/) So, if we go back to our 85kg powerlifter with 20% body fat who is aiming to lose around 8% body-fat (7kg), they should be aiming to lose 0.7kg a week. This means their initial cut should take ten weeks (7kg / 0.7 kg = 10 weeks), and their target body mass is 77kg. What about if we wanted to build more muscle? How much muscle could we expect to gain and how quickly? The first step in assessing how much muscle we could expect to gain is to assess how long you have been training seriously. If you are unsure about where you fit in, ask your coach. Training Status - Beginner. Intermediate Advanced Muscle Gain per month - 0.9-1.2kg. 0.45kg-0.9kg. 0.25kg (source: https://rippedbody.com/) There are several strategies around bulking. A dirty bulk (gain weight as quickly as possible), a controlled bulk (maximise muscle gain without gaining unnecessary fat levels) or a lean bulk (maintain maximal leanness while adding muscle). A dirty bulk is usually a bad idea. Your maximal rate of muscle growth is controlled by training experience, not by calories. Eating more calories above an appropriate level just leads to elevated fat gains. In contrast, the so-called lean bulk or lean gains strategy, aims to build muscle without gaining fat. This can be done, but it will take much longer to build significant muscle mass. The best way, in my view, is to take the middle ground and perform a controlled bulk. This maximises your muscle gain whilst controlling the fat gain. For most people, a ratio of 1:1 muscle : fat gain is realistic. So, to use another example, what if we had a beginner to training, who weighs 70kg at 8% body fat. In this case, the lifter should be trying to gain muscle. As they are a beginner, setting a target of 1kg of muscle a month is a realistic goal. If they aim to gain 1kg of muscle a month, they should expect to gain 1kg of fat per month. Over a 6 month bulk, they should aim to gain 6kg of muscle and 6kg of fat, leaving them at 82kg and 15% body fat. Calories So what happens now? We’ve established what we weigh, what body fat levels and our goals. The next step is to calculate your calories. The first step is to assess your daily, non-exercise activity level. Fundamentally, if you’re an office worker, set it at taking it easy. If you work in a more physically demanding job, set the activity level to beast mode. The second step is to enter how many hours of exercise a week you perform. If you’re training 4 times a week, using 6 hours of exercise as a baseline is typical. Once these have been entered, you’ll be able to calculate your daily calorie targets. Going back to our cutting powerlifter - the output is for them to eat 2546 calories a day. Our bulking beginner has a target of 2711 calories a day. Alongside these numbers, there are then the target macros - Protein, Carbs and Fat. What are these numbers and what should you do with them? Macros Macros or macronutrients refer to a food type required in large amounts in the diet; principally Fat, Protein and Carbohydrates. A common idea is that whilst calorie balance determines weight loss and gain, macronutrients control whether fat is lost or muscle is gained. This isn’t entirely right, but if you get the macro-nutrients correct then it will be much easier to reach your physique goals. The three major macronutrients are Protein, Carbohydrates and Fat. Each macronutrient has a certain amount of calories. Protein and carbohydrates both contain 4 calories per gram, with fat containing 9 calories per gram. The calorie target is then made up of a certain amount of protein, fat and carbohydrates per day. Protein Protein is essential for strength and physique athletes. Primarily, protein is essential for muscle repair and growth, thereby helping us recover from training. When we are trying lose weight, eating enough protein is essential to maintain as much lean muscle mass as possible. When we are trying to gain muscle mass, protein is important to help us to build as much muscle as possible. The amount of protein that you consume is dependent on your lean body mass and your diet goals. If you’re cutting, protein intake should be slightly higher than if you’re bulking, with a range of 2.3-3.1g/kg of LBM when cutting and 1.6-2.2g/kg of LMB when bulking. Using the Danny Lee Macro calculator*, we are given 5 options for the protein multiplier (0.8-0.9-1.0-1.1-1.2). If you are cutting, select a value of 1.0-1.2 for the protein multiplier, and a value for 0.8-1.0 if you’re bulking. The reason that protein is boosted in a calorie deficit is two fold; firstly higher levels of protein in the diet when you are in a calorie deficit helps preserve muscle mass. Secondly, protein is a high satiety macronutrient - it helps you feel fuller. When you are in a calorie deficit, eating a higher proportion of your diet from protein will help you feel fuller, making it easy to stick to the diet. Fat Dietary fat is an essential macronutrient - it has a key role in maintaining normal hormonal function, especially testosterone. It should never be completely removed from your diet as this will have adverse health effects over the long term. Fat is the most calorie intensive of the macronutrients, with 9 calories per gram. During a cut, the easiest way to reduce calories is therefore to reduce fat consumption. As fat is over twice as calorie rich as carbohydrates, reducing fat intake can cause a big drop in calories. There is a minimum value that you shouldn’t go below - broadly below 0.9g/kg LBM. During a bulk, fat should make up around 20-30% of the total calorie intake. Using our trusty macro calculator, we have a range of values for the fat multiplier (0.4-0.5-0.6). If you are trying to cut, select the minimum value, 0.4. If you are trying to bulk, select 0.5 or 0.6, to see which value results in a fat intake between the 20-30% range. Carbohydrate The final piece of the macronutrient puzzle are carbohydrates. When setting up a diet and setting your macronutrient targets, carbohydrates make up the remaining calorie amounts once your protein and fat goals have been set. Whilst carbohydrates are technically just the ‘rest’ of your diet, they are still important. Carbohydrates have important roles to play in feeling your workouts, replenishing muscle glycogen and play a role in hormone regulation. Putting it all together Let's go back to our two examples. Our 85kg powerlifter who is trying to cut has calculated they have 20% body fat, giving them a LBM of 68kg. They want to cut down to 12% body fat, giving them a target weight of 77kg. They have a relatively sedentary job and do 6 hours of training a week. This gives them a calorie target of ~2546 cal/day. They are cutting, so they select a protein multiplier of 1.1 and a fat multiplier of 0.4, giving them final macro targets of 186g Protein, 296g Carbohydrates and 67g Fat. The second example is our 70kg beginner who wants to pack on some muscle. They have a calculated body fat of 8%, giving them 64.4kg LBM. They are aiming to gain a kilo of muscle per month over the next six months, giving them a target LBM of 70.4kg, and a body fat percentage of 15%. They have an active job and also do 6 hours of training a week, giving them a calorie target of 3073 calories per day. As they are bulking, they are choose a protein multiplier of 0.9 and a fat multiplier of 0.5, giving them final macro targets of 162g Protein, 402g Carbohydrates and 90g Fat. Summary In this guide we have outlined the key components of setting up a diet, what the components of a diet are and how to calculate your calorie and macronutrient targets. This should serve as the basis for your diet. In the next article we will discuss in more detail how you can use different strategies to hit your calorie and macronutrient targets, as well as discuss the importance of micronutrients. * The Macro calculator is available to clients in the website's 'Client Portal'.

Nutrition Tips for the Beginner. Getting a handle on your diet can be hard. Especially if things like calories and macros seem alien to you as maths is hard sometimes. Precision Nutrition has a handy (that's a pun) way of dealing with this. For women it is suggested to have - - 1 palm sized portion of protein. - 1 fist of vegetables. - 1 cupped handful of carb dense foods. - 1 entire thumb of fat dense foods. For men it is the same but double that. Now once you get used to this style of meal building you can assess how you feel after a couple of weeks. Are you gaining weight from this but want to lose? Maybe have a smaller portion of the carbs or fat. Are you losing weight but want to maintain or gain? Add in a little to the carbohydrates and see how that goes. Nutrition isnt easy, and while calorie counting, if done correctly is the surest way,it is also the hardest. So to begin with, try this "handy" method. This post is taken from my instagram in May of this year. It received plenty of good feedback so I thought I would lay it out here also.
If you find that you need a more specific route to tracking your food then I would recommend educating yourself on calories, macronutrients and how to get what's right for you. If you need help with this then message me, by all means. I hope you enjoyed this! |
