Very well-supported argument by the fact that obesity tends to accumulate in the well-off who can afford lots of food, while poor folks tend to be slender. So yeah, clearly lower spending on food would reduce obesity.
Cheap GLP-1's will probably finally bend this curve for lower incomes. Muscle-mass (via paid meds) will be the new marker of wealth/status for upper incomes.
