Fact: It doesn't matter what time of day you eat--it's how much you eat during the whole day and how much exercise you get that make you gain or lose weight. No matter when you eat your meals, your body will store extra calories as fat. If you want to have a snack before bedtime, make sure that you first think about how many calories you have already eaten that day.

Try not to snack while doing other things like watching television, playing video games, or using the computer. If you eat meals and snacks in the kitchen or dining room, you are less likely to be distracted and more likely to be aware of what and how much you are eating. (If you want to snack while watching TV, take a small amount of food with you--like a handful of pretzels or a couple of cookies--not the whole bag.)
