Just some advice:

If you do something - say, physical training and eating right for a few months - and you decide to stop doing it for a few days and eat whatever you want and slack off... Don't eat a Wendy's Baconator.

Just... Don't. Or rather, don't do it if you're a rational and normal person. If you're into either bending over or onto the toilet for a few hours or so, go for it.
