Ugh why do they have to take it to the extreme? It's a "treat" for me to enjoy BBQ food & even ice cream! But I also had to get up early to run, and I'll be skipping alcohol so I can enjoy the "treats."  What I don't understand (like you said) is why they have to eat MASSIVE amounts of food? Stuff themselves until they're uncomfortable & then still stuff more - how is that fun?
