Statistics that fail independent corroboration are excluded.

Body statistics turn everyday questions about weight, fitness, and health into measurable facts, and the most recent figures are harder to ignore than ever. In the United States, measured obesity prevalence among adults is 41.9% as of 2023, yet more than 1.4 billion adults worldwide were still insufficiently active back in 2019. Layer in rising chronic disease, the accelerating markets for weight management and digital health, and treatment costs that can exceed thousands per year, and you get a picture where health trends move fast and differently across populations.
