It is the training adaptation and overall calorie intake.

But it is not the protein which forces your body to adapt and grow big. Protein Intake During BulkingĪ bro scientist might recommend a super high protein intake such as ~2.5-3.5g gram per kilo of body weight, expecting bigger gains. Thus, 2 bowls of daal and 2 eggs a day is FAR from being sufficient. We lifters are interested in building new muscle tissues which requires a positive nitrogen balance. Hence, doctors and dieticians are prescribing protein intake for general well being (maintaining neutral nitrogen balance in the body) and NOT building muscle. Why? That's because most of the nutritional research is on: General Health or Preventing Malnutrition of sedentary individuals.

With the risk of overstepping my bounds as a coach (because they have a 5+ years of a degree and I do not) the recommended daily protein intake by doctors and dieticians is far below optimal.

In a nutshell, protein is the most energy inefficient macronutrient but is absolutely essential for muscle building. Protein is broken down into amino acids and it serves a structural role as a building block of muscle tissues. Unlike the other three macronutrients, it is very inconvenient for the body to get usable energy from protein. Protein is one of the four macronutrients (carbohydrates, fats, alcohol being the other three) the body needs. Like most things in science, the answer isn't black or white but finding your perfect grey spot. On the other hand, some gym bros (bodybuilders and powerlifters) recommend a very high dose, that is up to 2.5 - 3.5 grams per kilo of body weight. Some (doctors and registered dietitians) recommend a very low dose of protein ~0.5g gram per kg body weight per day. There is so much talk about protein and different experts recommend different amount of protein intake that it creates a lot of confusion. NOTE: For the ease of readers, I will be talking about protein in grams per Kg of bodyweight, unlike grams per 'pound' of bodyweight.
