Eat balanced meals. Keep exercising. you're not going to gain flab that way.
I just read that you're better off eating 500 calories of jellybeans than you are 500 calories of a soft drink, because your body has no mechanism to let you know how much you are consuming when it's a liquid. So stay away from sugary drinks, make sure you're getting plenty of fruits, whole grains, legumes and vegetables.
And remember when you are riding hard, you might want to eat simpler foods (sort of the opposite of what i just told you) .. time off the bike, eat the well balanced harder to digest stuff..

i forgot to add: you got a lot of very good advice on the last thread you started. So read it again.
