The Flat belly diet came about as a collaboration between once Prevention editor Liz Vaccariello and dietician Cynthia Sass which led to the publication of the Flat Belly Diet book in 2008. On top of promising rapid weight loss (a 15-pound drop in 32 days) the Flat Belly diet plan is designed to specifically target belly fat which has been shown to increase the risk for a number of conditions such as heart disease, diabetes and cancer.
The Abs diet is an eating pattern and exercise regime which aims to improve health and appearance. The diet is designed by former Men’s Health editor David Zinczenko with information and guidelines available in a number of his books including The New Abs Diet, The Abs Diet Ultimate Nutrition Handbook, The Abs Diet Eat Right Every Time Guide and The New! Abs Diet Cookbook.
