Many women who exercise don't understand why they are not losing weight. New research shows hormones might be to blame.

You've probably tried at least one of those crazy fad diets. Now get the truth on dieting!

Diet and exercise can help people lose weight, but research now shows that how well you sleep can also have an effect on body weight.

New research suggests it's not just what you eat, but when you eat that either helps or hinders you from losing weight.
