Just stating the obvious -- losing weight (and likely lowering HbA1c/having other benefits) for 18 months is probably infinitely better than never losing weight at all.
What an extremely worrying incentive structure. Especially if coupled with reduction in regulation. The companies making the food, telling you what to eat, how to feel, how to fix yourself, all behind a convenient subscription you'll never want to never cancel, it's great how it all ties into each other. The billionaires must be so happy.
