Both diets are simular
Try the mcdougall diet or engine2 diet. You can eat all you want [I know it sounds impossible right] as long as it is the approved foods. We have been on this diet for 3 years. It is a way of life that will change your life for ever. 150 lb weight loss and never be hungry, sign me up. It is a starched based diet with the science to back it up. Basically you avoid anything with a face or a mother, and no added oil. [added oil causes heart problems with no health benefits].
I know several people who got the by bypass, all with questionable results. A friend died years after getting it done with a constriction in his stomach that poisoned him. My uncle lost 70 lbs to be thin enough to do it [I did not quite understand this, if you can lose 70 lbs, why not skip the bypass and keep doing what is working] He had it for 16 months, and then removed it because of problems he was having. He has since gained all his weight. Another friend just kept overeating to the point it had to be removed.
The bypass will make you sick so it will be hard to eat. Why not try a diet that will let you eat all you want and still lose weight? I love to eat and could never make it on a restricted diet. All my health issues are now gone and I am normal weight, yet I eat more than all my family members combined :)
You have to do something different to get a different result. Being on this diet for 3 years we have tried to get others to try it, but people are so resistant to change. I would much rather change my eating than go under the knife.
