What are the top diets that actually work?

Here are a variety of opinions from WikiAnswer contributors:

• I'm on a diet and these are my favorites, but this is just a personal opinion: insanity workout and nutrition guide claims to help lose weight in 60 days, banana diet, 5 bites diet, lemonade diet. These diets don't work for everyone.

• In my opinion, the best diet is the Paleo Diet also known as the Paleolithic Diet, Stone Age Diet, Caveman Diet, or Hunter-Gatherer Diet. It is an Excellent diet for both health and weight loss.
