The formula for losing weight is simple: eat less and exercise more. But, it's not really all that simple, is it? Long-term weight loss isn't impossible, but you do have to be committed. Having a weight loss plan for your success is a good start. Weight loss is achieved by both diet and exercise. It is also achieved by persistence. If you "fall off the wagon" one day, pick yourself up and continue your healthy lifestyle the next. Don't give up!
