âThe third theme of inaccuracy [in the weight-centered health paradigm] relates to the depiction of relationships between body weight, morbidity, and mortality. Life expectancy is the primary health indicator used at the population level. The claim that life expectancy is reduced as a direct result of body weight higher than the ânormal weightâ BMI category is not supported by large epidemiological studies. The largest epidemiological study ever conducted followed 1.8 million people over a 10-year follow-up period and demonstrated an inverted U shaped relationship between BMI and life expectancy, with the highest life expectancy in people with a BMI between 26 and 28 (in the âoverweightâ BMI category) and the lowest life expectancy in those with a BMI under 18 (in the âunderweightâ BMI category). Those with a BMI between 18 and 20 (in the âhealthy weightâ BMI category) had a lower life expectancy than those with a BMI between 34 and 36 (in the âobeseâ BMI category;).â
