The 11 Worst Diets Out There

Also known as: the Hollywood Diet, formed in the 1930s — this diet involved eating half of a grapefruit, in addition to a cup of coffee and a teeny bit of lean meat and salad. While there are multiple versions of this diet to surface since then (people never know when to end a sequel, huh?) this is the most common and straight forward.

This diet limits your cals from 800-1,000 ... once again, this is under the recommended calorie intake and while it does show results, it won't keep working after you've completed it.
