Why Can't I Keep The Weight Off?

This has been a very soul searching week for me. Since diagnosis with diabetes last October, I have maintained a weight loss of only about 5 pounds. It is really time for me to evaluate why I can't seem to take my health seriously and get this weight off. I feel that one of my main problems is my ability to inhale food. I just don't give my body enough time to let me know that I have had enough. I eat a varied diet and don't have much of a sweet tooth, but my portion sizes are huge. I am discouraged by diets and weight-loss plans and have been on many all my life. I am even considering surgical solutions. I have always thought that they are a bad choice. However, recent studies suggest that surgical solutions can send diabetes into remission in over 80 percent of cases. It has also been noted that bariatric surgery is the most effective tool for losing and keeping weight off. It is becoming obvious to me and apparently backed by most statistics that telling an obese person to just eat less and exercise more is not effective. From what I can research 90% of those who lose weight with traditional attempts regain their weight. I know from my diet classes that most of us in there are still fat! I look at all the people in my life that are fat and although some lose weight, all of them have gained it back. I know from psychology that "past behavior is the best predictor of future behavior", and that is why we stay fat. Yes we can change, and some people do, but most of us will not and that is the reality. Almost all the gurus, and friends that mean well seem to have never been 100 lbs over their ideal weight. I have tried weight watchers, nutra-system, atkins, and have been going to HMR for over ten years and I think I have yet to meet an educator that is keeping 100lbs off permanently. It seems my doctor's can't seem to lose weight or have never been seriously overweight either. Obese people like myself started our problems early in life. We really should have been more worried then. If we never got this heavy the first time, I think we probably would have had a better chance. My understanding is that once we gain additional fat cells they remain with us even if we lose weight. This gives us a tendency to gain weight more easily than someone who never has been overweight to begin with. Doctors and people who have never been really overweight seem to forget this. Our bodies are different than yours. It really is different for you than us. Yes, we can lose weight just as you might have, but it is harder for us to keep it off. Our extra fat cells are hungry! I am really beginning to believe this. I know I can lose weight...and have done so many times. I just find it impossible to keep it off without making it a total obsession. I know when I lost 100 lbs 9 years ago that I was working far harder than someone who was my weight at the time who had never been seriously overweight. I don't think telling people that diet and exercise is the only key to weight maintenance in  someone who was obese is the end of the equation. It is an important part, but I think more research must be done. I really think something is missing here. It could be the fat cells I spoke of, a metabolic deficiency, or something we haven't found yet. There is too much focus today on losing weight when the real problem is keeping it off permanently. At this point, I am going to use the best available evidence to find a permanent weight maintenance solution.
