- Imperial College London researchers led a global study involving nearly 2,000 scientists, analyzing 4,050 studies with 232 million participants to track obesity trends from 1980 to 2024.
- United States adult obesity prevalence reached 40–43% in 2024, with the rate of increase slowing, while childhood obesity has plateaued at 20–23%.
- United Kingdom adult obesity rates hit 27–30% in 2024, among the highest globally, with childhood obesity stabilizing at 10–12%.
- France may have begun to reverse its obesity trend, with adult prevalence estimated at 24–25% in 2024, down from previous growth trajectories.
- Naveed Sattar noted that English-speaking nations are performing poorly on obesity, urging the UK to learn from countries where rates have stabilized.
- Low- and middle-income countries continue to experience rising obesity rates, with accelerating trends in some regions, raising concerns about future diabetes and cardiovascular disease.
Why it matters: Public health strategies in high-income countries may be gaining traction as obesity growth slows, but rising rates in developing nations risk overwhelming health systems already strained by infectious diseases and limited resources. The divergence underscores that no single solution fits all, demanding tailored policies.
