> I have a thermostat, and ingesting chemicals changed the set point. People who keep on gaining weight until they die must have a broken thermostat set on "high". It can't be psychological. This misses something important. If your weight is the thermostat's setpoint, then your BMR is the A/C unit, and your calorie intake is the ambient outdoor temperature. If your A/C unit is out of whack, then you'll need to move to a cooler climate (lower calorie intake) in order to get to a comfortable temperature. For example, women have a lower BMR than men and must eat less to maintain a healthy weight. > But everyone who has spent much or all of their life at a normal weight, should know it doesn't take supreme effort or fanatical accounting. It doesn't require not eating when you feel like you're starving. Only it does sometimes. You can't see how someone can slowly adapt unhealthy eating patterns over time? Or, as perhaps in your case, they need medication which changes their BMR? Once your ghrelin production/cycle no longer matches your BMR + physical activity, you may feel like you're starving even though you've already met you're calorie intake needs. Fortunately, we can change how hungry we feel in the long run just as we can change how much we eat, and there are plenty of examples of that. I don't think it's a gaslighting conspiracy to say that much.
