What percentage of the population is on GLP-1 drugs right now?

Well "According to KFF polling from May 2024, 6% of all adults report that they currently are taking a GLP-1 drug, and 12% report that they've ever taken a GLP-1 drug".

Is 6% enough to affect crop prices? Presumably some ag economist can weigh in. Note it would only be a reduction per person, not a full 6% reduction in consumption.
