Why gastric bypass if calorie deficit works?
I've seen those shows on TV where someone weighs many hundreds of pounds and they have obvious mental issues that explain the weight gain (emotional eating, death of a spouse, childhood trauma/abuse, etc).
You also see the doctor tell them to lose 50+ lbs before he does the surgery. OK I get it, it's to get them eating better which they will need to do after surgery.
So if weight loss can be done by eating better and eating at a calorie deficit, why is gastric bypass even a consideration? I don't necessarily mean the 600 lb people because those are special cases. I mean even people that are 300 lbs. If you are 600 lbs you probably do the need the surgery as that is an extreme case.
The bypass is permanent and potentially life threatening. If you can steadily lose weight, even say 75-100 lbs per year then why go to the drastic step of surgery?
I could be wrong but to me it seems like these people tend to view bypass surgery as the magic pill or quick fix to a long term problem. People get the surgery and then rave about how amazing it was when really they could have accomplished the same thing by changing their eating habits (albeit more slowly). Guess what it took years to gain the weight so what's wrong with taking a year or two (maybe longer if you're doing it safely) to lose the weight?
I'm not trying to start something here. I'm serious, I'm trying to figure out in what cases surgery is really necessary. I think there are many cases where if people ate better and ate at a deficit, they would be better off in the long run. Surgery is extreme, dangerous, and costly.
