The "solutions" are all about using willpower, of which we each have a limited amount. It's not clear whether exercising it strengthens it or weakens it. Same old same old. "It's your fault, because of your character defects." Yeah, whatever. Not helpful.
A few days ago someone posted here a link to a study about new weight loss drugs that actually work: up to 30% weight reduction in "severely obese" people, iirc.
