You must loseweight to be successful in losing weight. You should commit to this desire, not just say that you want to lose weight. The best way to lose weight is to create a goal, write it down, then stick to it.
For a goal is not just about the weight you lose or want to lose. You can write a goal using your body measurement or bodypercentage lost rapidly, or it can be the size of your desirable clothes.
Set your goals in such a way that they are attainable. For example, I want to lose 15 pounds by Christmas or I want to drop 2 dress sizes at my sister's wedding.
