re: Had a minor surgery yesterday and have to take off 2 weeks

It's only two weeks. There's a good chance you go back to the gym feeling wayyyyy better than you did before. I take a week off every year and usually go back feeling a lot better. Even if you don't slow down on the eating you're not going to gain that much in two weeks. You should be able to quickly lose it, especially since it sounds like you have a good bit of discipline and know how you're supposed to eat.

Glad they got that cancer out. Hopefully your recovery goes quickly.
