A Danish study tracking over 85,000 adults found people with BMI below 18.5 were nearly three times more likely to die early compared to those with BMI between 22.5 and 24.9. Those at the lower end of the “healthy” range faced doubled death risk with BMI between 18.5 and 19.9, while BMI 20-22.4 carried 27% higher risk. Surprisingly, people with BMI 25-35, typically labeled “overweight” or “obese,” showed no significant mortality increase. Only those with BMI 40 or higher saw substantially raised death risk at 2.1 times higher. The research suggests the safest BMI range may be 22.5-30 rather than the traditional 18.5-24.9. (Story URL)
