It is every bodybuilder's goal to gain muscle while keeping fat gains at a minimum, or better yet, to lose fat simultaneously. While this is extremely hard, it is not entirely impossible. It just takes a level of dedication, discipline and self awareness that most tend not to have. For maximal muscle gains with minimal lipid storage I suggest the following nutrional protocol:
Phase I
1) Consume 2,000 Calories every day. Any more will be stored as fat for energy during cardiovascular aerobic activity.
2) Eat 1 gram of protein per 3-4lbs of bodyweight for 20 weeks
Phase II
1) Consume 2,000 Calories ED
2) Eat 1 gram of protein per 2lbs of BW for 8 weeks
Phase III
1) Consume 2,000 Calories ED
2) Eat 1 gram of protein per 3-4lbs of BW for 20 weeks
REPEAT.
Cycling protein intake levels result in the body optimizing macronutient intake ratios, accelerating nitrogen reuptake as a result of an influx of anabolism induced by varying levels of protein in the body. This will result in accelerated muscle growth without stress on the kidneys.
