“Our study, which features the largest and most globally representative sample to date, along with more rigorous statistical analysis compared to previous research, aims to shift perspectives on the relationship between fitness and body fat.”
Researchers from the US and UK compiled and analyzed information from 20 research revealed throughout 1980 to 2023, with a complete pattern measurement of 398,716 individuals. The entire research included information on physique mass index (BMI), cardiorespiratory health, and mortality threat.
The workforce discovered that the danger of an early loss of life for people with weight problems who have been match was much like that of individuals classed as match and of regular weight.
