This diet has practically become the gospel to dieting today from celebs to regular people. In case you haven't heard, basically, you eat small meals throughout the day, every three hours. The 3-Hour Diet is very controlled—eat breakfast at 7 a.m., have a 100-calorie snack at 10 a.m., lunch at 1 p.m., a second 100-calorie snack at 4 p.m., dinner at 7 p.m., and then soon after dinner enjoy a 50-calorie treat. To follow the diet correctly, dieters need to make sure that they stop eating at least three hours before going to sleep. It seems easy enough to follow, but requires you to take snacks at times where your job or school may not allow. I guess you can probably adjust it somewhat depending on your hours in the day.
