Optimal Protein Intake for Bodybuilders. Protein. It’s every bodybuilder’s favorite macronutrient and for good reason. Protein is extremely essential, super satiating and amazingly anabolic. Strangely, very few people think it’s a bit too accidental that the optimal amount of protein your body can assimilate in a day is exactly 1g/lb. ![]() ![]() Of course, I know you read my articles for their scientific merit, so let’s look at the literature on the effects of daily protein intake to find out if 1g/lb really is the optimal amount of protein intake for maximum muscle gains. Studies on the optimal protein intake. All values in the bullet point list below are expressed as grams of protein per pound of body weight per day. All of these studies controlled for energy intake, either based on individual requirements or by setting energy intake to be equal in all experimental conditions, so that only the proportion of protein in the diet varied between groups. If the studies were based on unreliable methods such as nitrogen balance, a marker of lean body mass changes, I only included them if they controlled for sweating and dietary adaptation periods. Protein oxidation did increase in the high protein group, indicating a nutrient overload. The authors suggested that 0. Based on nitrogen balance data, the authors recommended 0. This recommendation often includes a double 9. As such, this is already overdoing it and consuming 1g/lb . The picture below summarizes the literature. As you can see, 1. But I train harder! Protein is extremely essential, super satiating and amazingly anabolic. Four CA Regional Agritourism Summits in February & March. The University of California Small Farm Program and UC Cooperative Extension advisors in four California. ![]() ![]() If you still think you need more than 0. Well, Tarnopolsky et al. Resistance training causes both breakdown and synthesis to increase, normally with a favorable balance towards synthesis. As you progress in your training, the body becomes more efficient at stopping the breakdown of protein resulting from training. Since less protein now needs to be replenished, this increase in nitrogen retention means less protein is subsequently needed for optimal growth. Secondly, the more advanced you are, the less protein synthesis increases after training. As you become more muscular and you get closer to your genetic limit, less muscle is built after training. ![]() This is very intuitive. The slower you can build muscle, the less protein is needed for optimal growth. It wouldn’t make any sense if the body needed more protein to build less muscle, especially considering that the body becomes more efficient at metabolizing protein. But what about when cutting? A final objection that is often heard is that these values may be true during bulking or maintenance periods, but cutting requires more protein to maintain muscle mass. The researchers took a group of endurance trained subjects and had them consume either 0. They also added a thousand calories worth of training on top of their regular exercise. So these guys were literally running on a 1. Talk about a catabolic state. What Is The Best Ab Training Routine? Find out what other people from the message boards think. Pink Shares Gym Selfie, Says She's 'Obese' by 'Regular Standards': 'Stay Off That Scale, Ladies!'. You may republish this material online or in print under our Creative Commons licence. You must attribute the article to NutritionFacts.org with a link back to. However, the protein intake of 0. Nitrogen balance, whole- body protein turnover and protein synthesis remained unchanged. A further review of the literature on the optimal protein intake in a deficit can be found in this article of the research on protein by Eric Helms. Also, the supposed difference in nitrogen sparing effects of carbs and fat are negligible (Mc. Cargar et al. 1. 98. Millward, 1. 98. 9). Neither actually spares protein though. Only protein spares protein. I think the protein sparing idea came from a wrong interpretation of the nitrogen balance literature showing more lean mass is lost in more severe caloric deficits. A simple explanation for that finding is that the more total mass you lose, the more lean mass you lose. No surprises there. As such, there is simply no empirically substantiated reason to think we need more than 0. If anything, you could reason the body should be able to use more protein during bulking periods, because more muscle is being built and a lot of other nutrients are ingested that may enable more protein to be used. The only people that may actually need more protein than 0. Androgen or growth hormone users definitely fall into this category, but I don’t exclude the possibility that some adolescents do too. If you reach peak testosterone production while still growing (in height), your unusually high levels of growth hormone and testosterone might increase your protein requirements. There’s no research to support it. Those rare individuals with amazing bodybuilding genetics could also qualify, but unless your father happens to be a silverback gorilla, you are most likely just like other humans in this regard. The 1g/lb Myth’s Origin. Why is it then that everybody says you need to consume 1g/lb? Aside from the facts that there don’t need to be any good reasons for why people believe in a myth, that myths tend to perpetuate themselves via conformism and tradition, and that the fitness industry is flooded with myths, here are some plausible grounds for the . Steroids enable you to assimilate far more protein than you’d normally could. There are so many studies showing protein is good for you, it’s hard not to think more of it is even better. There are actually several industry- sponsored studies showing absolutely miraculous benefits of consuming more protein (see for example the studies by Cribb). The excess will simply be used as energy. However, protein sources tend to be expensive compared to other energy sources and variety generally beats monotony with regards to your health, so satiety and food preferences are the only reasons I can think of why somebody would want to overconsume protein. Take Home Messages. This already includes a mark- up, since most research finds no more benefits after 0. Have a look at the Bayesian PT Course. Click here to see the scientific references.

Chicken Big: Poultry & Obesity. We know vegetarians have considerably lower obesity rates compared to meat- eaters, but why? This study controlled for all that. In essence, they took men and women who ate the same number of calories a day, ate the same amount of vegetables, and fruit and grains, same amount of exercise. Men and women who ate less than a single? If you remember back to that study of hundreds of thousands of men and women, poultry consumption appeared to be the worst, but maybe it was reverse causation, meaning obesity led to greater chicken consumption, and not the other way around. This new study controlled for that, adjusting for dietary habits, yet found the same thing. Chicken consumption was most associated with weight gain in both men and women. Compared to those who didn.
