You eat really well Monday through Friday, and once the weekend rolls around, you splurge a little (or a lot) to reward yourself for being so good all week. Eating the foods you crave is essential when it comes to eating healthy, but you don't want to overdo it on the weekends, undoing a week's hard work. According to a study in the International Journal of Obesity, those people who ate a consistent amount of calories all seven days of the week were 50 percent more likely to maintain their weight than those who followed strict diets only Monday through Friday. With that said, it's best to stick to consuming the same amount of calories each day, and allow yourself a few 100- to 200-calorie treats throughout the week. Then once Saturday comes, you won't feel the need to binge on foods you've missed out on.
