If you choose to follow this strict dietary plan, you are required to eat specific foods in exact portions. Needles to say, you must avoid overeating. After three days, you are allowed to get back to your regular eating regime but only in the next 4-5 days. Your controlled consumption of food will speed up your metabolism to burn more fats,  which will help you lose weight radically.

The goal of substituting 3 days diet with 4-5 regular eating days contributes to restoring the fats your body has lost during three-days diet plan and it also prevents you from starving. Extreme low calorie intake for three days causes your body to slim down and triggers your metabolism leading your body to a ketogenic reaction

Essentially, the weight loss is caused by the loss of bodily fluids instead of fats. During the 3 days period of The Cleveland Clinic diet, the dieters can take 1000 calories including the consumption of tuna. Together with doing exercises The Cleveland Clinic diet will give remarkable results in the long run. In the end, you should keep in mind that successful losing weight requires a proper knowledge on this subject and, above all, endurance.
