According to the Gallup National Health and Well-Being Index, America’s adult obesity rate has fallen to 37% in 2025, down from 39.9% in 2022 — a small but significant drop after decades of stagnation. Over the same period, the number of people taking injectable anti-obesity drugs more than doubled, from 5.8% to 12.4%. Coincidence? Perhaps. But correlation has rarely looked this convincing.
