Your ideal world thinking: "Fast food is a weight-loss nightmare. It's loaded with fat and calories. Even if I feel deprived, I'm not eating it again."
Real world solution: When it comes to fast food, portion size is key. Downsize your choice in any fast-food chain to a kid's meal (with water or a sugar-free soda) and you'll have an indulgence of about 400 to 500 calories. If you crave fast food, have it as an occasional treat. It will help prevent deprivation, which can lead to a loss of control and overeating. Preplanning is the best defense.
