Lean Mass is 2500kcal per pound, NOT 3500kcal

I had a discussion with a few people on the facebook study group page recently.

There is a lot of confusion surrounding this concept, and it’s because it isn’t highlighted very well in the book. In the very first paragraph on the top of page 224 it talks about the kcal requirements of lean mass being 2500kcal/lb, not the usual 3500kcal/lb. This has profound implications for many of the exercise science questions – I suggest you commit this fact to memory.

This distinction tripped me up for the longest time….

Due to me being at least a little bit OCD about understanding concepts and being honest with myself about what I know vs. don’t know, I had a question on a practice exam that I could not get the right answer to. I’m good at math – my numbers were right, they just weren’t coming up with the right answer. Convinced that the question itself couldn’t be wrong – I went back and re-read the question carefully….

“…assume all of the weight gained will be lean mass” — hrmm, I wonder why they would point this out? MAYBE LEAN MASS HAS A DIFFERENT REQUIREMENT…at least according to the NSCA.

So I pored back over chapter 10 and finally found it, unbolded, unhighlighted, hanging out inconspicuously on the aforementioned page 224.

According to the NSCA:

LEAN MASS = 2500kcal

FAT MASS = 3500kcal
