  • Obesity. Some research shows that people who follow the Zone diet lose weight and reduce their waist size. The diet seems to work about as well as other weight loss programs such as the LEARN and Ornish diets. The Zone diet might work as well as the Atkins diet. But some research shows that the Atkins diet is better for losing weight.
