Weight loss occurs when you use more calories than you consume. What you eat must digest. It cannot if you eat in the Zone. When queried about the Zone, nationally recognized sports nutritionists say no. None of these athletes are fat.
Inactivity is a key to being overweight.
There is no basis to Dr. Sears' claim that 75 percent of Americans have a genetic defect that makes them fat when they ate carbohydrates. In reality, people only lose weight using the Zone approach because it's lowered their calories, not because it's low in carbohydrates. If a person eats 1,200 calories a day from cookies but is used to eating 3000 calories a day, that person will lose weight. No trick to that. This Zone diet isn't supposed to be done just to lose the weight quick and then get off and eat like normal.
