Jorge Cruise, a renowned fitness expert, proposed the 3-hour diet plan, which involves eating breakfast at 7 a.m., lunch at 1 p.m., and dinner at 7 p.m. Alternatively, you can have an early dinner and finish eating three hours before bedtime. The plan also includes two 100-calorie snacks, such as nuts or string cheese, to be consumed in between meals. By spacing out meals and planning ahead, the 3-hour diet aims to promote healthy and consistent eating habits.
