> All humans will lose weight at 0 calories per day

It might be meant in jest or just as a rhetorical point, but it is really the core of your argument. Basically it’s a simple recipe for anyone to lose weight if they don’t care about any of the consequences, including straight dying. So then is there any point for losing weight to them ?

It reminds me of the rule of metrics: when you replace a complex goal with an easy to mesure number, that number will be optimized irrelevant of the complex goal being met or not.

My personal position is that people should accept there’s no simple and universal rule if they deal with a complex system. And god are our bodies complex.
