Volume selling, volume eating go together
I am like most people in that I have a) tired of "the latest study" because it seems you can always find one that says the opposite of the last one and b) interest in studies that confirm my world view.
But that's not why I'm sharing this nugget:
Headline: Report Suggests That Your Supermarket May Affect Your Weight
Story (in part): "... participants who shop at discount supermarkets, in supermarkets in areas with poorly educated consumers, or in supermarkets far from their own neighborhood had higher body mass indices (BMI) and waist circumferences."
First of all, duh. Since the supermarket is where we get food, it's pretty fair to say that your supermarket affects your weight.
But also: The headline has it backwards! Warehouse stores sell in volume, so of course volume-eaters are more likely to patronize them.
If you've ever shopped at Costco, you've seen what I mean. I am thankful that they did not have such stores back when I was actively overeating.
