>the fasting required for bariatric surgery actually provides a large proportion of the benefit of the procedure

Can confirm. My wife had surgery ~3 years ago. I supported her by eating the same things she was for prep and throughout the surgery. We lost about the same amount of weight, through ~1600cal a day and exercise. I wanted to get down about 25lbs lower than my lowest during that time. But, a year ago my wife was diagnosed with cancer, and that process totally screwed with our plans, and we both gained weight, her quite a bit less than me.

The last ~6 weeks I've been restricting calories again, and have started the journey back to where I want to be. I will say that the surgery really impacted her hair badly, which she didn't love. Despite taking all the best vitamins, her hair went from thick to somewhat thin.

If you can get rid of the things that trigger you and stick to low calories and exercise, you'll lose weight. The surgery helps, but committing to low calories is going to get the results. And a friend who got bariatric surgery but wasn't committed to lifestyle changes, within a year was back to her original weight.
