Almost 80% of American adults are either obese or overweight.

Nov 8, 2026

Previously: Almost 80% of American adults are either obese or overweight. [Distorted]: The CDC's most recent measured data, from August 2021 to August 2023, show 72.4% of US adults are overweight or obese, and 40.3% are obese. The direction is right and the number is very high, but 72% is closer to seven in ten than to almost 80%. This verdict would be wrong if a newer national measured survey shows about 78 to 80% of adults are overweight or obese.

Now: Almost 80% of American adults are either obese or overweight. [Distorted]: Measured NHANES data for adults 20 and older in August 2021-August 2023 report 40.3% with obesity and 32.1% overweight without obesity: 72.4% combined. Severe obesity is already included in obesity and must not be added again. The health problem is substantial, but this source does not establish an almost-80% current estimate.
