If you’re trying to lose weight, then there’s a good chance you’re looking for a 3 day diet menu. 3 day diets have been popular for decades, even before the internet came around. If you’re old enough, you might remember your friends and family passing around photocopies of the various 3 day diet menu options. Nowadays, most of us get them in email form. There are several different 3 day diets that are popular, with names like the Mayo Clinic Diet or the Cleveland Clinic diet or the Tuna and Water diet. Each of these has a different 3 day diet menu, but they all work by similar methods. What most of these diets do is use a combination of low calories and low carbohydrates to elicit extremely fast weight loss, usually somewhere in the neighborhood of two pounds a day.
