The 3 Day Diet is not associated with the prestigious Cleveland Clinic. It is an urban legend that is not nutritionally sound, and the only reason it causes weight loss is because it is so low in calories, not because of any food combinations or metabolic reactions."
The plan yields about 1,000 calories a day which has the ability to lower metabolism so when you revert back to normal eating, you regain weight even quicker.
And the diet is so monotonous, dieters gladly return to their old eating habits. Hands down, the 3 Day Diet is not conducive to changing habits or encouraging a healthier lifestyle, which are fundamental to weight control.
Because the 3 Day Diet is so low in carbohydrates, it's likely the initial weight loss is primarily water weight, as carbohydrate encourages your body to retain water. As soon as the dieter goes back to consuming a normal amount of carbohydrate, the water weight comes back.
Experts worry that when dieters can't follow restrictive plans like the 3 Day Diet, they blame themselves and think they've failed. Fad diets are not sustainable for any period of time, and it is the reason so many people throw in the towel, feeling frustrated that diets don't work, when in reality it is the diet, not the dieter.
