Currently I am also keen on fitness. I am tying Intermittent fasting and Warrior diet as dieting regimen.
But it is interesting to know that yoga usually do 4-6 water fasting days for detoxifying and clearing all body system. It is pretty difficult but IF and WD is a good start. I am telling you this in order to let you know that eating lot of food and supplements (like creatin, amino, etc.) requires a rest for you body. The effect is very sensible.
Keep in mind that that quantity of food is not normal for anybody. In my opinion Fitness is for vanity, the outdoor sport is for health.
