Okay to be overweight, but not obese
Ideally, people should all strive to be "normal weight," right? Obesity is proven to be very bad for your health, so, despite being less detrimental to your health, being overweight is still likely to be worse than being normal weight, right?
A new study published in the Journal of the American Medical Association has found that overweight people, in fact, have a six percent lower risk of all-cause mortality than normal weight patients. Using a meta-analysis of 97 studies covering 2.88 million people, researchers considered normal weight people to have a BMI between 18.5 and 24.99, overweight people to have a BMI between 25 and 29.99, and obese people with a BMI over 30.
The researchers offered some potential explanations: heavier patients were more likely to receive optimal medical treatment, cardioprotective metabolic effects of increased body fat and benefits of higher metabolic reserves.
