You are doing an awful lot of mental gymnastics in search of a boogeyman that does not exist.

How mammals ingest, process, store and burn energy has been well understood for a very long time.

You know why some domestic dogs and cats are overweight? Is it ADHD or microplastics? Of course not, it’s because they’ve been eating more energy thaN they have been burning for a while.

Ozempic only stops you wanting to eat more, which perfectly proves the point. The boogeyman you are searching for is eating more energy than you burn.
