BMI string test: Dr Zoe reveals how to determine your risk of a serious Covid infection
BMI is a comparison of your weight and height and reveals if you’re a healthy weight. The NHS website offers a BMI calculator. Living with excess weight puts people at greater risk of serious illness or death from COVID-19
According to figures published by the government last July, nearly 8 percent of critically ill patients with COVID-19 in intensive care units have been morbidly obese, compared with 2.9 percent of the general population.
So knowing your BMI is incredibly important. But for those who want a “quick guide” and don’t have a measuring tape or scales to hand, Dr Zoe Williams revealed the string test.
Appearing on ITV’s This Morning, she explained: “Make sure it’s a long piece of string, stand on it, do a rough measure of your height.
“Pick up [the string] from the tip of your toe, fold it in half, and see if it will wrap around the widest part of your tummy.
