You are unable to weigh less permanently because you are trying to satisfy your emotional needs by putting more food in your mouth than you need for nourishment. YOU MADE YOURSELF OVERWEIGHT OR FAT! You knew that you were gaining lots of weight that you didn't want to gain but it was more important - emotionally-  for you to put all that food in your mouth than it was to weigh less. Really!
It's that simple. So when someone tells you that you should put less food or different foods in your mouth you are unable to do that for any length of time. That is just a diet and diets are a colossal waste of time and money because you need all that food in your mouth - and the foods that make you feel good or stop you from feeling bad- more than you want to weigh less. SO, THE REALITY IS THAT ALL DIETS ARE BASED ON EMOTIONAL DEPRIVATION!!!!  You will never emotionally deprive yourself of things you need to feel good or stop from feeling bad.
So in order to weigh less, permanently, is to learn how to eliminate that emotional need for food that is keeping you captive - and weighing too much. The first thing is to tell yourself the truth about why you made yourself overweight or fat. Once you understand that the rest is easy. You will be able to weigh anything weight you want to weigh. 
And it's free. Keep your money. You will need it to buy new clothes.
Stick with me and I will teach you how to do this.
