You're right I seem to be referencing bad data, and the excess is probably more like 10-50 cals/day.

Whatever the figures are, what's interesting to me is the growing secular impact on an entire sector of the economy (the most stable and inelastic sector). If eating right means spending 5% less, extrapolating that across the entire sector, not just for the 16% using GLPs today, could be catastrophic

I suspect ultimately though supply will meet demand and prices may even rise for the food people are still eating
