We know that fat is complicated, and there are many ways that we approach measuring it. While BMI has become the standard, it’s utility is lessened by recent data showing that people who were overweight (BMI 25- 30) or had grade 1 obesity (BMI 30-35) had lower mortality than those with normal weight (BMI 18.5-25). Higher mortality kicked in at BMI levels above 35. This present report offers a reasonable explanation of this seeming paradox, by showing that waist-hip ratio had a much stronger correlation with mortality. (As an aside, some of us might wonder where our waist is; they used the upper point of the hip bone for the waist measurement, and the “greatest circumference of the buttocks” as the hip measurement).
