Fat but Fit? Study Debunks Health Myth
20 Mar
Summary
- Obese adults face higher heart, liver, and kidney disease risks.
- Excess body fat may cause disease regardless of metabolic health.
- UK study followed over 150,000 Britons for 12.6 years.

A comprehensive study involving over 150,000 participants in the UK has challenged the popular concept of being 'fat but fit'. Researchers from Imperial College London found that obese individuals, even those without high blood pressure, diabetes, or abnormal cholesterol, face substantially increased risks for heart, liver, and kidney diseases.
The study, which tracked participants for a median of 12.6 years, indicated that excess body fat itself is a significant driver of these health problems. Men classified as obese but metabolically healthy were 46% more prone to heart disease and over twice as likely to develop fatty liver disease compared to healthy-weight men. Women in the same category showed similar elevated risks.
When metabolic abnormalities were present alongside obesity, the health risks escalated dramatically for both men and women. The findings underscore that obesity is not a benign condition and emphasize the critical need for early intervention to mitigate long-term cardiometabolic outcomes. Current UK statistics show nearly two-thirds of adults are overweight, with over a quarter being obese.
