Yes?

A lizard whose bite makes its prey eat less is crazy but it exists.

A lizard whose bite makes its prey eat more is also crazy, but maybe it exists?

The first lizard is literal, the second lizard is a stand-in for whatever mystery force I am postulating the existence of.

When you look at the historic literature on diet and nutrition from the first half of the century it's like looking into another universe. People are obsessed with getting people to eat more to prevent malnutrition even when food is freely available. Something changed.

The food changed substantially. Lot's of other stuff changed too, but we're talking about the transition from malnutrition to obesity over a few generations and the make up of what we ingest strongly impacts that.

Mass production and consumerism of food created perverse incentives that resulted in drastic changes to diets - different macronutrient profiles, new ingredients (emulsifiers, artificial sweeteners), and new manufacturing byproducts (residual solvents, pfas, plastic). You can still opt-out of mass produced food and move to the bush to live a subsistence life, and you'll still be ingesting plastic and pfas.

Part of the reason this is so hard to grapple with is that (in the USA) almost no one alive was an adult before the food industry industrialized. I'm 40 and my parents and grandparents rode the initial waves of processed garbage.

I feel it’s still not clear if you understand that ozempic causes weight loss because it causes reduced eating or if you believe ozempic causing less eating is incidental to the weight loss
