During the past several years, a misconception—the so called “obesity paradox”—has been creeping into the medical literature. This paradox is a medical hypothesis which holds that obesity (and even high cholesterol), counter intuitively, may be protective and associated with greater survival in certain groups of people, such as very elderly individuals or those with certain chronic diseases. It further postulates that normal to low body mass index or normal values of cholesterol may be detrimental and associated with higher mortality in asymptomatic people.

But is there any truth to this hypothesis? As we note below, the answer to this question is, no!

    A large international study that included Harvard researchers links a high body mass index (BMI)-a calculation used to determine if a person is overweight-to a risk of early death, and contradicts the idea that it’s possible to be fat and fit. Researchers pooled the data from 239 studies of more than 10 million people in 32 countries. They excluded people who had smoked, had a chronic condition, or died within five years of follow-up, leaving about four million people. Of those, researchers analyzed people’s BMIs (Body Mass Indices). A healthy BMI (non-obese) is considered to be in the range from 18.5 to 24.9. Researchers observed that study participants with a BMI of 20 to 24.9 were the least likely to die during the study period; people with a BMI above that were significantly more likely to die during the study period, especially men with high BMIs. The findings, published Aug. 20, 2016, in The Lancet, don’t prove that high BMIs cause early death, but they do suggest being overweight matters.

The bottom line: Extra fat puts you at risk for developing diabetes, heart disease, and cancer, so make weight control a priority, and avoid making phony excuses for being fat!
