We've come a long way from the days of crash diets that were severely limited and just plain ridiculous. The hottest diets these days might still not be the healthiest or most balanced ways to lose weight (healthy nutrition and exercise wins every time!), but at least they include more than cabbage soup.

3 Most-Popular Fad Diets

1. The Dukan Diet. The Dukan Diet plan has been made famous by Kate Middleton. With a fit body like that, it's no wonder women around the world are trying it.

2. The 17-Day Diet. This quick diet boasts itself on never leaving dieters bored or in a deprived rut, as the diet lasts only -you guessed it - 17 days!

3. The HCG Diet. The most controversial of the three most-popular diets listed, this extremely low-calorie diet is only recommended under the care of a physician.
