It may sound like another crazy fad diet, but there is actually some substance to this peanut butter-endorsing diet endeavor. There is plenty of science showing that the childhood favorite can actually prevent heart disease and promote weight loss. That is in part due to the high numbers of monounsaturated fat found in peanut butter.

As satisfying as peanut butter is on the stomach and the soul, it is high in calories and fat. However, that doe not mean you can't put peanut butter to good use, especially if you're following this innovative, health-enhancing plan. You certainly will not feel deprived, according to the diet's mastermind Holly McCord.

On the peanut butter diet, the recommendation is to consume 400 to 600 calories of peanut butter a day. Women are allowed to consume 1,500 calories a day with 4 tablespoons of peanut butter. Men, on the other hand, follow a plan of 2,200 calories a day including 6 tablespoons of peanut butter. Forty-five minutes of exercise a day is also one of the basic principles.

Your menu will appear as something like this. For breakfast, fill your plate with peanut butter maple syrup waffles and 1 cup of fat-free milk. Lunch is a tuna salad with six ounces of tuna, two teaspoons of mayo, 1/2 teaspoon of Dijon mustard and two tablespoons of chopped carrots and celery, along with 1 1/2 cups of baby carrots and bell pepper strips. Drink 3/4 cup of V-8. Have a piece of fruit as a snack. For dinner, enjoy Tahitian Chicken with Peanut Butter Mango Sauce served over 1/2 cup brown rice and served alongside 1/2 cup cooked spinach. Your dessert is a 1 1/2 inch slice of angel food cake topped with 1 1/2 cups of mashed strawberries. The meals are not just healthy but satisfying as well.
