How To Understand The Effect of Genetics On BMI

The Truth About Mothers And Their Daughters’ Resemblance On BMI Charts

By Andrew Wilson


Is it true that mothers and their daughters’ resemblance on BMI is a sure thing? It’s easy to assume that a daughter might take after her mother’s eating habits and have a similar BMI as her mother, for many reasons. But they might not be the reasons you’d think. But first, let’s make it clear what BMI is.

BMI or body mass index is nothing more than the measure of a person’s weight in relation to her height. A person’s weight in kilograms is divided by a person’s height in meters, squared (which is simply a person’s height times itself—if I’m 1.5 meters tall, I would take 1.5 times 1.5). The resulting number is her BMI. A normal BMI is anything from 18.5 to 24.5, and 25 to 29.9 is considered overweight, with anything above that considered obese. A BMI below 18.5 is considered underweight. BMI is a good general measurement for most people, although very muscular people usually measure as overweight or obese because BMI doesn’t distinguish between muscle weight and fat weight.
So, back to mothers and their daughters’ resemblance on BMI, does it guarantee that a daughter will be overweight if her mother has a high BMI? Will a normal weight mother raise a normal weight daughter? Will the daughter be underweight if the mother is too skinny? While nothing is certain 100% of the time, there are some factors that push those answers more toward a yes than a no.
