I'm confused by the language...

Within six months of starting a GLP-1 medication, households reduce grocery spending by an average of 5.3%.

A household doesn't take Ozempic, a person does. Are they implying that if everybody in the household takes Ozempic, as a group they see a 5% reduction? Or, any one person in the household causes a 5% reduction for the group? The average household in the US is 2.5 people...

How can they measure individual grocery spending habits? People buy groceries for their whole household.

If the dataset includes household size you could limit the analysis to that subset. Alternatively you could focus on households with lower average basket sizes and hypothesise that those households have fewer adults. Obviously those measure aren't going to be anywhere near perfect but might be informative.
