The formula to lose weight is simple: eat less and exercise more. So then why aren’t more dieters successful? Because, it’s not easy to ignore cravings, cut calories, and bid farewell to the foods you love.
However, your appetite must be controlled if you’re going to lose weight.
Donald Hensrud, MD, explains, “Cutting calories through dietary changes seems to promote weight loss more effectively than does exercise.” 
The good news is willpower isn’t the only tool at your disposal. You can also use the 10 best natural appetite suppressants.
