During the study, the researchers observed more than 42,000 people for 10 years, while monitoring their BMI and a new indicator – the percentage of weight that was located below the chest, and above the hips: the so-called “WHtR” (waist-to-hip-ratio).
Scientists concluded that
- People with a normal BMI, who had a high WHtR were 22% more likely to become overly obese, acquiring a number of diseases that are peculiar to people with excess weight.
- People with an identical BMI who had a low WHtR maintained both physical fitness and health.
An even more significant fact is that in people who belong to the group with a high BMI, which under the old scale would be considered overweight or obese, the percentage of diseases, associated with weight, also correlated with weight distribution on the body.
Let’s formulate it in a simple way: the weight and not its ratio to the height is not that important. It is important how much of this weight has settled on the abdomen and waist.
Scientists explain it the following way
First,muscles are heavier than fat, so even an overweight person can have a lower BMI, than a well-pumped athlete. Naturally, this does not tell us anything about the health condition and can not serve as a ground for conclusions.
Second,if a generally healthy person begins gaining weight, he grows stout evenly (arms, legs and torso fatten together.
In a number of diseases or abnormalities, weight begins to accumulate in the abdomen, while the arms, feet and face remain thin. BMI does not change much, yet it is a reason to be worried.
SO, HOW TO CHECK IF YOUR BODY IS OK
The formula is simple:
- Divide the waist circumference into the circumference of the widest part of your body.
- If the value you get is below 0.85, everything is OK.
