Your mental status does have a lot to do with your body size and percentage of body fat. You need to decide... Do you want to be obese or slim, fit and healthy? It takes determination and a strong desire to be successful to lose weight and get the healthy body you have always wanted.
If you want to lose weight and sustain it, you need to make changes in your lifestyle, as well as follow the right diet. You can get rid of excess body fat, but the change starts with you. It starts with your attitude.
Always remember that it's mind over body.
Stay Healthy... Stay Blessed!!
