We have all heard the dogma that it is impossible to build muscle while losing fat but I think differently now (only because of my own modest gains). Someone with significant amounts of stored body-fat can eat a low calorie diet and use their stored fat for energy to build new muscle mass.
Assuming proper amounts of amino acids, micronutrients, and stimulus are supplied why should our body care where its energy comes from - whether stored as body fat or consumed in diet?
The rules for fatties:
- train to get stronger
- eat nutrient dense, real food (think lots of vegetables and some animal based protein)
