A Danish study of over 85,000 adults shows that individuals with a BMI below 18.5 have nearly three times the risk of early death compared to those with a BMI of 22.5-24.9.
The research challenges traditional views, suggesting that being slightly overweight may not increase mortality risk.
A U-shaped curve indicates higher mortality risks for both underweight and severely obese individuals.
The study calls for a reevaluation of BMI as a health measure, noting it overlooks factors like fat distribution and health conditions.
Critics highlight that BMI cutoffs may misclassify healthy individuals from diverse backgrounds.
