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...
See my parallel comment... are they reporting 1/4 of a household eats 25% individually (for a 5% reduction across a family of 4). Or, does one person eating 5% less cause the other 3 to also eat 5%... if it's the latter, this potentially has health impacts across people who aren't taking the drug.
