ZONE
This higher protein, lower carbohydrate diet is supposed to decrease hunger, then weight.
An exact meal plan based upon each person's gender, activity level, and current percentage of body fat is designed to include 40 percent of its calories from carbohydrates, 30 from protein and 30 from fat. All meals and snacks follow this 40-30-30 distribution ratio, causing the body to work within its peak performance "zone" for maximum energy and weight loss.

Upside
. You will lose weight on this diet due to the very low calorie intake while you enjoy foods high in protein such as roast beef and steaks. Specific meal plans are available to guide you into the "zone."

Downside
. The diet is very low in carbohydrates, which can quickly sap your energy levels. It's also low in fiber and some vitamins and minerals due to the drastic reduction of foods such as pasta, potatoes, and bread products. Figuring out how to make each and every meal and snack follow the 40-30-30 ratio can be daunting.
