I heard you were discussing my article over here. After reading some of the comments, I realized a way to make the Protein Calculator more accurate for bodybuilders. Previously, the calculator figured your ideal weight from your height, and then based the protein levels on that weight. But of course, bodybuilders have extra muscle mass and so they weigh more than non-body-builders of the same height without being overweight. So now you have the option to enter your body fat % into the calculator, and if you're a woman with a body fat % of 22.5 or less, or a man with a body fat % of 15.5% or less, the calculator will use your inputted weight as your ideal weight and base the protein levels from that.
So for bodybuilders, the number of grams of protein has gone up a little. For example, for a 190-lb. male bodybuilder, the old protein levels were 85 to 121 grams (using the standard 1.2-1.7 g/kg of ideal body weight), or 9-13% of calories assuming a "Very Active" diet. The new way, using the full 190-lbs. as the ideal weight, gives protein levels of 104 to 147 grams, or 11-15% of calories. This is still achievable on a vegetarian diet, as common vegetables have more protein than that, even after adjusting for reduced bioavailability.
