The idea that it is possible to be overweight or obese but not at increased risk of heart disease, also known as the "obesity paradox," has been challenged by a study of nearly 300,000 people.
Published in the European Heart Journal on Friday, research showed that the risk of heart attacks, strokes and high blood pressure increases as weight increases beyond a body mbad index (BMI) of 22.
BMI is used to determine if you are in a healthy weight range for your height.
The risk of cardiovascular disease (CVD) increased more steadily the more fat a person carries around the waist, according to the research, although it is generally believed that excess weight increases a person's risk. Cardiovascular diseases as well as other diseases like cancer.
Studies have also been conducted suggesting that, especially in the elderly, overweight or even obesity may have no effect on deaths from CVD or other causes, and may even be protective, especially if people maintain a level reasonable aptitude.
This is known as the "obesity paradox".
But a large study conducted by a team of researchers at the University of Glasgow provided evidence against this theory.
"Any public misconception of a possible protective effect of fat on the heart and the risks of stroke should be questioned," said lead author Dr. Stamatina Iliodromiti, clinical professor of obstetrics and gynecology.
It was possible, however, that the story may be different for people with preexisting conditions, such as cancer patients, noted Dr. Iliodromiti.
Researchers badyzed the health of 296,535 adults of European descent recruited for the Biobank study of the United Kingdom between 2006 and 2010.  The badysis of the monitoring data collected in 2015 found that people with a BMI between 22- 23 had the lowest risk of cardiovascular disease (CVD).
As the BMI increased above 22, the risk of CVD increased by 13% for eve 5.2 kg / m2 increase in women and 4.3 kg / m2 in men.
Similar increases in the risk of CVD were observed when the researchers observed the waist-hip and waist-height relationship and body fat percentage. 19659003] "By maintaining a healthy BMI of around 22-23 kg / m2, healthy people can minimize the risk of developing or dying from heart disease," said Dr. Illiodromiti.
The National Heart Foundation said that carrying excess body fat around the middle of the body is more of a health risk than in the hips and thighs.
