I can not stick to a healthy diet. I'm 21.11 stone (300lbs) roughly. I feel horrible about my weight. I saw my doctor today and she commented on my weight gain, that really kicked my confidence. I know how to lose weight I just cannot stick to it because I get bored of it and after I lose 10lbs etc.. I go back to my unhealthy way. I need some real advice on how others have done this, or if you haven't maybe you have some ideas on how I can do this? Please help. I need motivation.
