I have that problem as well, because it seems like every weekend, my husband wants to eat out more often. And with him purchasing that fast food and bringing it home, it makes it more difficult for me to avoid temptation. 95% of the time, I can be good and not indulge in any of the junk food brought home, but once in a while, I give in, and have a few fried tortilla chips w/ salsa. I just have to make sure I don't overdo it, since my check-in day is on Mondays; and all that hard work that I've been doing throughout the week won't be outdone by the weekend temptations. What I find that helps me on the weekends is trying to stay busy (ex.- doing housework, playing with my daughter, or exercising.) I know it may seem cliche, but it really helps me. By the time I do those things, it takes my mind off being hungry. Also, keep plenty of healthy snacks in the fridge (carrot sticks w/ low or no fat ranch dressing, apple slices, low-fat string cheese, etc.), so when you absolutely must have something to snack on, at least it's something healthy. Watch out for activities that may "trigger" you to eat (watching t.v. show marathons on weekends really makes me want to snack.) Hope this helps.
