On: How long til we're all on Ozempic?

[grecy]

Sure, a mammal does not HAVE to store excess energy.

But that is entirely irrelevant when a mammal eats less energy than they consume for a while. In that instance they MUST burn some stored reserves or break the laws of physics

[immibis → grecy]

An equally plausible hypothesis is that the mammal feels lethargic and does not consume more energy than it eats.
