Survey: Americans want weight loss drugs despite high cost

Many Americans really want to lose weight—and a new poll shows nearly half of adults would be interested in taking a prescription drug to help them do so.

At the same time, enthusiasm dims sharply if the treatment comes as an injection, if it is not covered by insurance, or if the weight is likely to return after discontinuing treatment, a new nationwide KFF poll found.

Those findings display the enthusiasm for a new generation of pricey weight loss drugs hitting the market and illustrate possible stumbling blocks, as users potentially must deal with weekly self-injections, lack of insurance coverage, and the need to continue the medications indefinitely.

For example, interest dropped to 14% when respondents were asked if they would still consider taking prescription medications if they knew they could regain weight after stopping the drugs.

One way to interpret that finding is “people want to lose a few pounds but don’t want to be on a drug for the rest of their life,” said Ashley Kirzinger, KFF’s director of survey methodology. The monthly poll reached out to 1,327 U.S. adults.

The U.S. represents a large market for drugmakers who want to sell weight loss prescriptions: An estimated 42% of the population is classified as obese, according to a controversial metric known as BMI, or body mass index. In the KFF poll, 61% said they were currently trying to lose weight, although only 4% were taking a prescription medication to do so.

That gap between the 4% taking any kind of prescription weight loss treatment and the number of Americans deemed overweight or obese is the sweet spot drugmakers are targeting for the new drugs, which include several diabetes treatments repurposed as weight loss drugs.
