The Flat Belly diet promises a flat belly and weight loss of up to 15 pounds in 32 days.

Before one begins the 28-day plan they go on a 1,200 - 1,400 calorie, four-day anti-bloat jump-start period designed to reduce bloating and get dieters in the mind-set of a healthier eating plan.

The basic plan of the Flat Belly Diet is a 1,600 calorie Mediterranean-style diet with an emphasis on wholesome unrefined foods including fruits, vegetables, whole grains, nuts, beans, lean protein and very little red meat.

The authors believe that the secret ingredient in The Flat Belly Diet that whittles away belly fat is the addition of a monounsaturated fat, or MUFA, at every meal; these MUFAs are found in olives, avocado, nuts, seeds, dark chcoloate, soybean, flax and olive and sunflower oils.

During the 'jump-start,' period dieters drink 2-litres of daily "sassy water," a blend of spices, herbs, citrus and cucumber designed to reduce constipation and bloating.

Dieters taking part in The Flat Belly Diet do not count calories. Instead, they choose from a list of 28 interchangeable mix and match breakfasts, lunches, dinners and snack packs.

The Flat Belly Diet has attracted a lot of attention and it has been featured on 'Good Morning America,' and 'The Today Show.'

Whether you are a vegetarian or a meat eater, have food allergies or are lactose intolerant The Flat Belly Diet can be adapted to meet anyone's individual needs.

Within The Flat Belly Diet exercise is optional but always encouraged. An entire chapter of the book deals with a Flat Belly workout with diagrams and exercise and 28-day workout plan.

The Flat Belly Diet is written in the first person by Liz Vaccariello who is the editor in chief of 'Prevention,' along with Cynthia Sass, MPH, RD, nutrition director at 'Prevention.'
