What is a good juice diet for quick weight loss?

A good juice diet is Jason Vale's "7lbs in 7 Days" Juice Master Diet, according to Fox News Magazine. The diet advocates juicing and blending fruit and vegetables. Blending preserves the fiber in the plant which avoids the spike and precipitous drop in blood sugar common in juice diets.

Dieters experience health benefits by adding more fresh juice to the diet, even if they do not change the rest of their eating habits, states Jason Vale, author of "7 lbs in 7 Days." Dietitians recommend people approach juice diets with caution. Side effects include fatigue, headaches and a drop in metabolism which leads to sudden weight gain when the dieter resumes eating normally.
