Wow. One of those rare change your opinion readsÂ (for me, of course, YMMV). A must read and the devastating summary I’d select is this:
…the terrible truth is that, except through surgery, for the great majority of sufferers, obesity is an incurable disease.
This won’t be the case for ever, but really does seem that it is true for now.
NB obesity is BMI 30+: lower than that and you’re curable.
