Leptin works on the brain to suppress appetite. Doctors believe most obese patients are somewhat resistant to Leptin. A new study finds higher doses of leptin given by injection can overcome that resistance, but long term studies are needed to see if it is safe. If you're looking for foods to curb your appetite, try the produce aisle. New research shows the amount of fiber in the diet may be more important than the amount of fat.

They suggest eating 5 servings a day of fruits, vegetables, and whole grains to protect against both obesity and heart disease.
