If the issue is obesity (e.g., you need to shed over a third of your current body weight) then I agree that bariatric surgery is definitely an option to consider. The odds really are against you trying to lose that amount of weight via diet and exercise alone at the parent post suggests.

(Considering surgery is certainly a more helpful suggestion then, "Have you tried eating less and moving more?" like they are the first person to ever tell you that. The way different bodies process things is far more nuanced than that, involving so many factors including hormones, age, gut bacteria and heaps of other things, not just will power. The more we discover about nutrition shows how much we don't know about nutrition. End rant.)

From my own personal experience[1] I would consider a gastric bypass or gastric sleeve, but avoid a lapband - all other factors being equal.

Obviously seek competent advice from medical specialists on the matter before doing something irreversible.
