One common mistake people make is that they believe that as long as they exercise a lot, they can eat anything they want and lose weight. I noticed that exercise will help you lose weight only if you combine it with some other weight loss methods, such as dieting. Exercise cannot be an excuse for eating tons of food. I also noticed that dieting and eating little plays a lot more important role in losing weight. There is a connection between how many calories per day you eat and how much you weight. If you reduce the calorie intake, you will lose weight no matter if you exercise or not. Exercising will help you feel better, but it will help you less lose weight than dieting can.
