I will say, weight loss surgery requires a tremendous amount of work. Making sure you eat enough, don't eat too much, drink enough water, get enough exericse, get enough vitamins, etc. It's like regular weight loss in those ways, but with devastating consequences if you mess up. It jumpstarts weight loss and makes it go faster, but the stakes are really high if you don't change your diet and exercise. The problem is that it's sold as (and fats see it as) an easy way to lose weight that doesn't involve 'work' and that's why the surgeries don't 'work' in so many cases and/or lead to devastating health consequences.
