> where just eating less and doing more sport doesn't really work I can understand it not working because it's hard to eat less when attempting to lose weight (something I've struggled with for a long time), but I know if I eat less calories, then I reliably lose weight. I can drop 2lb a week very easily by maintaining a deficit, but I regularly fail in my long-term objective and bounce back when I get stressed and overeat back over 2000 calories/day. So at least for me (most/all people?), it's not that eating less doesn't work, it's the inability to do that (genes/depression/stress/environment/whatever) which is the root cause.
