How is "more than you require" determined? The reason I ask is because the Protein Prescription assumes you eat 7 days a week. A key Zone rule is "Never consume any more protein than your body needs to maintain your lean body mass, but never eat less. Eating too little is to subject yourself to protein malnutrition." That's the last thing I want, because the primary reason I Zone is to increase physical performance, rather than to lose fat.
If anything, I want to gain muscle. "[B]uilding one pound of new muscle mass per month is a noble goal. To do so, however, requires only one extra protein block per day in addition to the number of protein blocks required to maintain your existing lean body mass."
I don't eat more than 5 blocks per meal, because I understand that would increase insulin to outside the Zone.
Though it should be irrelevant to my question, here's my math:
I weigh about 165 lbs. with a 15% body fat percentage, so my lean body mass is ~140.25 lbs.
I work out 5 days per week (obviously not on fasting day), probably the Active activity level (0.8 g protein per lb. lean body mass), so my Protein Prescription is 112.2 g per day. 112.2 g divided by 7 g per block is 16 blocks.
If the Protein Prescription for a week (16 blocks x 7 days = 112 blocks) is divided into 6 days, it's 18.7 blocks.
Divided into 6 days, my meal portions are about the same as a "Large Male" on page 2 of http://www.crossfit.com/journal/lib...May04.pdf.
