Holy crap slow down. This thread gives me a headache. Every answer is met with more questions, the goals stated keep changing...
What do you want to do? Skills? Fence? Power and size?
If it's fence, talk to your coach. Power and size? Don't fear the fat - on your body, or in the food. Lean mass gain? It's tough, but Steve's idea of:
Heavy lifting + sprints + good food + sleep = strength + mass
is very good. Add a random IF day for extra leanness.
But trying to do all of those will pull you all over, man.
The question for Christmas dinner is whether to eat the whole cheesecake, or avoid it like the plague. I would be happy to do either, but I don't know what to do!
I have to assume this is a joke, right? Otherwise you're bonkers. Both responses are nuts. A whole cheesecake? If an upset stomach is your goal. Avoid like the plague? Treating minor issues, like a slice of CAKE, like a disease, is just as foolish.
