Don't set any weight-loss or weight-maintenance goals to rule out sweets and other junk foods. You're likely to crave that bowl of Cinnamon Toast Crunch cereal you've been avoiding so badly that you end up eating three times more than usual. Definitely splurge every now and then, but pick carefully and plan ahead.
Are you going out to eat with friends at a burger joint this week? If so, make a conscious effort to cook healthy meals leading up to the double date. Popcorn and soda are tasty treats at the movie theater, but if you must indulge, forgo the extra butter and choose diet soda instead of the full-sugar options. Two spoons and a large hot fudge sundae make for a sinfully delicious combination, but sharing a nice bottle of red wine at home is better for you and just as sweet. An added bonus is sharing the bottle of wine in a bubble bath for two!
