All free online diets that you obtain must include certain steps to help you lose weight.  One of those important steps must be to fix your poor eating habits that created your weight gain.  It’s your poor eating habits that probably slowed down your metabolism, added stress onto your body and made you gain enough weight that has forced you to find a diet.  Most diets are unsuccessful, not because they don’t create results, but because they don’t have permanent results.  If any diet that you use doesn’t help you fix your eating habits, you can’t expect to lose weight and keep it off.
