This is also taken from the "John Berardi" topic. When one is overfeeding, how can we determine the best macronutrients for each person? This is what I got from reading the materials around the forum: 1. If one is a skinny guy who got speedy metabolism, try to keep protein around 15% of the calories. This will cause most weight gain, not necessarily most muscle though. 2. If one gains fat easily when overfeeding, one has to increase protein to around 20 - 25% of calories to take advantage of the thermic effect. Then, one should choose whether to overfeed from carb or fat. Everyone reacts differently, some will get fat from carb overfeeding (high carb, low fat diet), some will get fat from fat overfeeding (low carb, high fat diet). Is there a way to determine whether one is more suited to overfeed from carb or fat? Thank you.
