How to tell if you’re really overweight – and it’s NOT by checking your BMI

More than half of the world will be overweight or obese by 2035, a damning report warned today.

This amounts to 4 billion people, according to the projections of the World Obesity Federation’s 2023 atlas.

It used BMI for its assessments, a figure calculated by dividing a person’s weight in kilograms by their height in meters squared. In line with WHO guidelines, a BMI over 25 is overweight and over 30 is obese.

But some experts claim the measurement should be scrapped, and replaced with the waist-to-hip ratio.

The simplistic method doesn’t take into account muscle or fat distribution, meaning a rugby player and a couch potato of the same height and weight would be given the same score.

It categorizes people as underweight (under 18.5), healthy weight (18.5 to 24.9), overweight (25 to 29.9) or obese (30 or more).

Looking at the hip-to-waist ratio offers doctors a better way of measuring obesity, advocates say.

It can help work out if someone is carrying excess weight around their stomach.

This ratio is calculated by dividing your waist measurement by that of your hips.

The value of the score is different in men and women.

In women, if you end up with a figure that is 0.8 or below, it is considered to be low risk.

For women, a low-risk score is 0.8 or below, while the moderate risk is 0.81 to 0.85 and 0.85 or higher.

In men, it is 0.95 or below, 0.96 to 1, or 1 or higher.

Studies have shown this extra weight around the belly can increase the risk of type 2 diabetes and heart disease.

Researchers in 2018 from the Mayo Clinic based in Minnesota, US, and St Anne’s University hospital in the Czech Republic, compared BMI to waist-to-hip measurements.

The researchers found those with a normal weight but with more fat around their stomach had an 87 percent increase in risk of problems, in comparison to those who didn’t store their weight around their belly.

The results also suggested participants were 52 percent more likely to have an increased risk of diabetes and high cholesterol if they had weight in their middle.

A study presented at the European Association for the Study of Diabetes in Stockholm, also argues for scrapping BMI in favor of waist to hips ratio.

Researchers measured how likely a person was to die early based on their BMI, waist-hip ratio, or fat mass index (FMI), which accounts for the amount of fat someone is carrying compared to their height.

Results showed having a higher waist-hip ratio increased the risk of death linearly.
