Your body can't magic up energy out of nothingness. If you reduce your caloric intake enough, you'll always lose weight.

So you're saying science is wrong? Cause I ran the experiment and it failed.

The reason is, of course, that your body can downregulate energy expenditure according to energy intake. I've observed my body downregulate to about 1,000kcal/day. No fat loss on a 1kkcal/day OMAD diet for 2 months straight. No exceptions.

If you get below the bare minimum (say 1kkcal/day for me) your body will start shutting down pretty essential systems like the immune system, you won't be able to concentrate, sleep will be messed up.

Yes, I've done all these experiments, obviously.

So by "science", you mean your n=1 "experiment" and not conservation of energy?

[exfatloss]

Yes, of course. Only takes 1 experiment to disprove a hypothesis, remember?

Conservation of energy is a whole other story and I don't see how it's related to fat loss.
