Km is a low BF% from what I can remember but not for certain the number. It would be interesting to know what you started out at. I have a feeling once he hits around 160 ish and around 12 % bf he will get a reality check. Also how often are you eating your meals? Several people on other boards claim that eating every 2 -3 hours is a myth. Reference Layne Norton in his thread on MD, just name dropping since people know him. I mean the guy is going to school to learn about this, so he must know something.
I'll give it to him the boy can repeat and recite a lot. Which is what learning basically is we for the most part become parrots. Just repeating a reciting what we see. Just like the whole protein argument. I say 1 -1.5 per lean body mass and others say 2.5 per pound of everything including fat! It's all a big mumbo jumbo and no one is right and no one is wrong.
Personally I just feel that Km is making a huge mistake by taking in this number of calories. Who knows the boy might be the next Natural Mr. Olympia. My point is cut back on the calories don't get ahead of your self with gaining weight. You're a smart young man with huge future ahead of you. I wish you the best of luck but I just think he's getting ahead of himself.
