In an article published in the Daily Mail, Dr. Michael Mosley, a British doctor, and journalist, explained in detail what he criticizes the body mass index (BMI), and a fortiori what he criticizes studies based on this index.
Although it gives an indication of the build of an individual, the BMI would be a “bad indicator” as to overweight and obesity, because it presents several flaws.
“You can, for example, be muscular with a high BMI. The muscle weighs a lot, […] which distorts the calculation. Fat weighs less. And for this reason, you can be quite light, with a low BMI, while having too much body fat, especially gut fat.”, Detailed Dr. Mosley.
To find out whether or not you are overweight and therefore threatened by cardiovascular and metabolic problems, the British doctor advises simply to bring a piece of string.
“Start by cutting a piece of string so that it is as big as you are”, Indicates the doctor. “Then fold this piece of string in half and try to wrap it around your waist.”, He adds.
If it is impossible to make ends meet, then it means that you are too overweight in your stomach., which is harmful to health.
“The accumulation of visceral fat is normally the result of a number of different factors, including excessive consumption of sugary and starchy foods, excessive consumption of alcohol (especially beer), lack of physical exercise, stress, poor sleep and, of course, genetics” Says Dr. Mosley, adding that some people are more prone to gaining stomach weight than others.
“The good news is that studies have shown that visceral fat responds well to weight loss diets and exercise”, Tempered Dr Mosley.
