The Grapefruit Diet

The Grapefruit Diet has been around for almost a century. Originally designed in 1930 by Kelly D. Brownell, Ph.D., The Grapefruit Diet promises a dream. That dream is the possibility of dropping up to 10 pounds in 12 days.

The premise of this diet is that if you eat a half a grapefruit before every meal, you will lose weight faster. That’s because advocates of The Grapefruit Diet believe that the enzymes found in grapefruit are the hidden secret to rapid weight loss.

Here’s the thing: This diet has three huge flaws. Number one, who wants to eat a half a grapefruit before every meal?!? Number two, it’s massively calorie restricted, which means you’ll gain the weight right back if you return to old eating habits. And number three, it doesn’t focus on permanent lifestyle changes needed to build healthy eating patterns.

So think twice before trying this radical plan. Do you really want to gain that weight right back? We hope the answer is no.

The Cabbage Soup Diet

Another diet plan promising a quick fix is the Cabbage Soup Diet. In exchange for randomly eating (of all things) cabbage soup for a week, those in the know say you’ll lose up to 10 pounds.
