TV chef Rocco DiSpiritoof "Now Eat This!"lost 41 pounds and is on a mission to teach people how to lose up to 10 pounds in 10 days. His revolutionary weight loss system is outlined in his book "TheNegative Calorie Diet." Chef DiSpirito is also known for his "Cook Your Butt Off" method in which cooking tasks make fat-burning negative calorie foods. His recipes include controversial ketogenic gluten-free, sugarfree and dairy-free meals. Here's more on weight loss with Rocco DiSpirito.

Eat all you want in negative calorie diet

Do you hate the calorie counting of weight loss?

Rocco DiSpirito says you can lose both with "calorie forward" or negative calorie foods. Unlike positive calories that add weight, negative calories subtract pounds because they burn more energy to prepare, eat or digest than they provide. Water is the most important fat-burner because it adds nothing but takes a lot of work to process.Foods high in water are negative calorie. DiSpirito's diet is gluten-free, dairy-free, and sugarfree. Calorie forward foods are vegetables, nuts, lean protein, and seeds (high in fiber and water). The best foods are almonds, apples, berries, citrus, cucumbers, cruciferous vegetables (cauliflower, cabbage, bok choy, broccoli and Brussels sprouts), green leafy vegetables, mushrooms, and the nightshades (peppers, tomatoes, eggplant).

You can lose as much as 10 pounds in 10 days eating this way.

Rocco DiSpirito says "Cook Your Butt Off"

In an effort to outrun obesity, diabetes, high cholesterol, and hypertension, you've got a choice: drugs or diet. DiSpirito chose to revamp his eating habits. One way to lower a food's caloric impact is in the preparation.

As a celebrity chef, DiSpirito is all about cooking, so his weight loss plan factors in labor-intensive food preparation--chopping, peeling, dicing, whisking, and whipping. He advises doing away with gadgets and doing it by hand. Burning off half the calories beforehand means you can cook your way to thin. His essentially ketogenic (high protein, high good fat, low bad fat) gluten-free, sugarfree, dairy-free diet promises a pound a day weight loss for up to 10 days. Another celebrity chef Graham Elliot lost 150 pounds with a similar low-carb diet.
