I agree completely, but most people could go 80% of the way just by eating 20% smaller portions of the same food they eat right now. Does it cost more to cook

I agree completely, but most people could go 80% of the way just by eating 20% smaller portions of the same food they eat right now. Does it cost more to cook smaller portions? I think even worst case scenario is it costs the same, e.g. you cook the same amount and throw 20% away (or it goes bad). What would help is if people stopped treating weight loss as some insurmountable problem.
