I can not possibly conjure the words to express my disdain for the fact that this procedure exists. I could see it being worth it if it were physically impossible to lose the weight any other way. In that case, you would be vastly shortening your life and damaging your health, but if it were your only option, at least you would gain some measure of quality to the little time you're giving yourself.
The thing is, for 99.9% of people there are other options. To pretend that this is your only option is to admit defeat. It is to give up on life essentially. We only get one crack at life, and people want to throw away years of theirs in order to not have to exercise and maintain a healthy diet? That's absurd.
Besides, if you start dieting and exercising, you will feel great, have energy, and actually look much better. Iv seen guys and girls who are overweight, but through the process of trying to turn it around, they began to look and feel better. They were still overweight, but looked pretty good. They had some muscle under their fat, they had energy and stamina, they had color in their faces, they were flexible, etc.
Iv seen people who got the surgery. They look pale, have sunken faces, and become extremely lethargic. I know one guy who did it and subsequently divorced his wife assuming he could do better now. Well, it didnt help his personality, and he still looked like shit, just thinner. No dice for him. He got what he deserved.
