The thing is, if you speak to obesity specialist MDs, they really do come at this in a different way. They have a much more nuanced view of how underlying metabolism / biology interact with CICO.

I know personally because I used to believe a puritan CICO, but had a "viewquake" moment speaking with them and had to change a lot about what I believe!

Importantly they try to focus exclusively on practical solutions for the population: what will actually work in the world. They detach themselves from a lot of the moralizing we see.
