This is the most sensible attitude I've seen people express that has led to meaningful weight loss, maintenance and as far as we can see across large timespans, lifestyle change.

It's incredibly hard to gain weight by eating whole or minimally processed foods. The destruction and recombination of foods (and their food matrix) into ultra processed foods is one of the driving causes behind people eating more because the artificial textures and softness is one of the main drivers of over-eating, especially of high calorie foods.

I'd wager that people could replicate the same satiety induced weight loss (to a slower, but safer extent) through minimising ultra processed foods than GLP drugs.

It reduces your supermarket shop to about 10% of the store. Almost anything packed and transported is out of the question, as are entire rows of capitalism-driven junk food.
