You're describing "starvation mode" and it's a crock of shit unless you are actually starving down to an unhealthy BMI. There is something called "adaptive thermogenesis" where your body will try to compensate for weightloss by trying to get you to eat more (hunger) and move less. This is what can be helped with a refeed (and why I do ADF, since it has built-in refeeds).
However, this effect normalizes over time as the body adapts to the new lower weight.
Otherwise, you stall because you use fewer calories when you weigh less, not because of "hormones". The adaptive thermogenesis is a real thing but the effect is much smaller than people seem to think. It is not enough to overcome a decent deficit; it's just one of those things that makes dieting suck a little more.
If you aren't losing weight, you are eating too much. Period.
