"No one would ever advocate consuming more protein than your body requires. But likewise no one should ever advocate eating less protein than your body requires. Either extreme - too much or too little - can create serious health problems.
Most nutritionists like to assume that the protein needs of all men and all women are uniform. We're told, for example, that every male needs 56g of protein per day, or that females require 45g per day. Unfortunately, the genetic and environmental diversity of humans make such simple-minded protein calculations meaningless. 56g of protein may be adequate for a male who weighs 154 pounds, has 23% body fat and is sedentary (the average American male). But if you're a male who happens to be larger, or have less body fat, or are more active, then that 56g of protein is not nearly enough to prevent protein malnutrition.
In reality, individual protein requirements are genetically different for every person on the face of the earth. One size does not fit all."
