He's train to bulk, and cut. Read his post again.THBench said:He's trying to cut
ginab said:Protein intake is also important, as it is involved with building and repairing tissues. This is less than you think though, 0.7 - 0.9 g per lb.

Both Nancy Clark and Julie Burns, registered dieticians specializing in sports nutrition suggest around the same range.
He definitely needs protein to feed his muscles. And you're right, his muscles do need more than 0.9 g/lb. However, every lb on his body is not muscle, and extra fat on the body doesn't need extra protein. Excess protein isn't stored as bulging muscles or used for muscle fuel. Gains are not going to come from excess protein, but from the work put in at the gym, and for more energy there, carbs should be the primary source.
As for where the numbers come from ... the FAO and the RDA for protein are based on data from long term nitrogen balance studies. The DRI comes from the National Academy of Sciences. N balance was determined to be achieved at a a N intake of 105 mg N/kg BW/day or 0.66 g protein/kg BW/day. Standard deviation to cover 97.5% of healthy people was 25%.
0.25 x 0.6g/kg BW = 0.15g/kg BW
0.6gkg BW + 0.15 g/kg BW = 0.75 g protein/kg BW
Since protein is not 100% digestible, the FAO committee used a figure closer to 92%.
0.75 g protein/kg BW x 100/92 = 0.8 g protein/kg BW
Note that this number is not per lb, bur per kg.
I know that was really long, but I hope it helped some.
AJP said:Interesting, but, although I do agree with you about the need for carbs and energy...gains come from diet more so than exercise.
There are tons of people who workout all of the time, but don't eat right and thus don't see results. That, and as evo puts it, "fat people finish marathons all of the time" is a prime example.![]()
AJP said:I do like the part about the extra fat not needing extra protein as well, I definitely understand that. I understand that Nancy Clark and Julie Burns are well-known, but the topic here is concerning cutting specifically, not just gaining muscle or just losing weight.
AJP said:Not all protein has the same bioavailability either, so it's hard to put one number on all forms of protein. For example, a whey isolate is higher than chicken and tuna, both of which are higher than beans.
AJP said:The numbers from the FAO and national academy of sciences, and the numbers/allowances they put out are tailored to the general public and the general population, correct? So it would be difficult to apply the numbers to everyone, much less a lifting based, and in this case, a cutting audience.
