What are the chances of me being approved for gastric byp surgery?

Do you wanna' hear the truth? Don't have this surgery, unless you like the idea of loss of muscle m from not enough protein, loss of your hair, possible loss of bone density, and a whole slew of other medical problems. Best bet for losing weight? Find an easy diet you can stick to, and find fun exercise. For a diet, try high protein, low fat, but not non fat, low sodium, diet. You should also try to replace as many simple carbs with complex carbs as you can, and drink plenty of water. Add more fruits and vegetables to your diet, too, and if you have a moment of weakness where you eat something that's not on your diet, acknowledge it, and move on, getting back on the diet without punishing yourself. Check with a Dr. before you start any diet and exercise program, including this one, and ask his opinion on the details. Good luck, you've got my well wishes.
