If it is true, that to maintain our present muscle mass, we must consume, "One Gram of Protein" per body weight pound, then it would then become necessary to consume More Protein to increase Muscle tissue mass.
Some science has shown us that "2 Grams of Protein per pound of body weight" are necessary for mass increases. But both are true, keeping in mind that each of us respond differently. Summarily "increasing" protein intake does not always render significant results.
The Human Body's ability to, "Process" increased amounts of Protein, is not likened to a "Mathematical Equation". For example, in the science of Math: 1+1=2. Likewise E=mc2. We see that there is an Equal Reaction to an Action. So one could expect to "Double" one's muscle tissue content, if one Doubled their Protein intake.
The Human Body simply does not respond in this manner. Too much Protein can interfere with the Liver functions, as well as other areas of the renal system. Water retention is the most common side affect.
We know that the human body can Only produce a maximum of 5lbs of Lean muscle tissue a year. So....those of you who have gained more are probably just retaining fluids.
The "Blurry Muscle" concern, most of you have, when you thought you had gained 20lbs of muscle in eight weeks??...ends you up in a panic. Driving you to diuretics, which immediately Flush your entire system of its Vitamin and Mineral content. The rest of it, being, strength loss, and fatigue which always leads to injury (whether spontaneous or Long Term)
