I heard some where that some people are so carbs sensitive that there diet is just mainly 80% protein!?
i no you need protein to build muscle but i also understand you need carbs as they increase insulin levels that is a storage hormone?
but also read that protein that is not used is converted to glucose which in turn will spike insulin levels.
so you could purely grow on a pure hight protein diet!?
just a question!
Please buy or rent this book.
I’ve never heard of straight-up carb sensitivity. Some people are allergic/sensitive to gluten, which is found in wheat–and, ironically, is a protein.
To answer your question quickly: yes, you could gain weight on a pure high protein diet, but it’s far from optimal.
More detail: It’s a question of calories. If you eat more calories than you burn, you will gain weight. That is true no matter what you eat. Optimizing your macronutrient ratio (carbs, protein, and fat) will ensure that you gain weight the right way–i.e., lean body mass, minimal body fat. If you’re not getting enough carbs in your diet, your body will break down protein for fuel, which is an inefficient process. You’re much better off getting your energy first from carbs and secondarily from stored body fat. That allows your body to use your dietary protein to build new muscle.
The most efficient way to gain lean body mass (i.e., muscle) while training is to consume most of your calories from carbs (in the neighborhood of 45-60% of your daily calories, depending on your body type/metabolism/goals), and the rest in protein and fat. A 45% carb, 35% protein, and 20% fat macronutrient profile is optimal in my opinion. Athletes trying to shed body fat to make a weight class or get into competition shape will sometimes drop their carbs very low, but this is only a temporary strategy.
