For the extra money you can stab yourself with some selmaglutide meds instead, so that you stop being obese.
Did this myself, lost 4kg in 1 month, and that has stayed off. You can even buy em cheap out of china, if you dare.
Net result is you're probably about as likely to die as you were beforehand (increased longevity from weightloss offset with scooter incident risk) but at least you'll have more fun.
