Chubby comedian Steve Harvey is halfway through a 21-day liquid "detox" diet, and he says he feels great. Today he tweeted, "Day 11 on the Martha's Vineyard detox I have not chewed food in 11 days that sounds crazy but I feel great and I know I am healthy." Harvey, 53, the host of "Family Feud" and a syndicated radio show, is following the diet plan outlined in the best-seller "Lose 21 Pounds in 21 Days." The diet is also called the Martha's Vineyard Diet Detox.

Harvey may feel healthy, but nutritionists frown on crash dieting.The liquid-only diet calls for people to consume only juices and vegetable broths. Protein and enzyme supplements are encouraged, as are coffee enemas, according to the book's website. But diets like this provide only temporary results, experts say.
