The magic ingredient behind the New York Times best-selling Flat Belly Diet!-monounsaturated fatty acids (or MUFAs)-may not only target stubborn belly fat, but may also help treat the underlying cause of type 2 diabetes: insulin resistance. The 5-week program includes a sensible diabetes-friendly diet that teaches you how to incorporate pasta, chocolate, and other "forbidden" foods-along with a MUFA at every meal-into over 150 sumptuous, satisfying dishes.
Flat Belly Diet! Diabetes also includes a gentle walking-based exercise plan, stress reduction exercises, advice on how to work with one's doctor and diabetes management team, and a journal to help track blood sugar. In just 5 weeks, 11 men and women who tried the plan lost as much as 12 pounds, improved their A1c levels, and lowered their cholesterol and blood pressure levels.
