That's what I said. No other problem with obesity has caused people to stop being obese. There is no reason to believe that Covid messaging will do that. Worse than that, the people who don't like the government telling them they should get vaccinated also don't like the government telling them they should eat healthier or exercise and will do the opposite on purpose, making the problem worse. The people who aren't in that group who are at risk already got vaccinated.
If we know that obesity is the biggest risk factor for Covid severity, it seems irresponsible not to adjust our messaging to make that crystal clear to everyone.
Everybody who can benefit from it already knows. We're discussing policy decisions. Policies that increase vaccination rates work. Policies that message obesity reduction don't work.
