I'm visiting my sister for a week during X-mas break (MERRY CHRISTMAS EVERYONE ZOMGGG!!!!!! )

Anyways, she ALWAYS eats out, I mean ALWAYS. It's nuts, she goes to sushi-bars one day, fancy restaurants the next, sandwich pubs following, so of-course, I'm forced to eat out too.

I don't really want to invade and ask her to buy me a bunch of groceries during my visit, so I'm going to have to f*** up my diet for about a week.

Is there any way to "detox" your body. I'm not worried about not being able to get back on the diet, I'm committed, I'm just wondering what you can do to help your body "recover" persay. Thanks guys!!
