'Fat but fit' doesn't diminish risk for heart attack, stroke

'Fat but fit' doesn't diminish risk for heart attack, stroke

The study, conducted by scientists at the University of Birmingham, shows that metabolically healthy obese people still have 50 percent more chance to suffer heart disease than those of normal weight.

He explains: "Obesity can affect the heart through known risk factors such as diabetes, high blood pressure and high blood fat levels as well as inflammation".

The new study, from the University of Birmingham, involved 3.5 million people, approximately 61,000 of whom developed coronary heart disease. It looks at the medical records of 3.5 million people in the United Kingdom between 1995 and 2015 to assess the legitimacy of the "fat but fit" theory.

Using records from 1995 to 2015, the researchers identified patients with a body mass index (BMI) of 30 or more but nevertheless appeared healthy, which was defined as exhibiting no symptoms of diabetes, heart disease, high blood pressure or high cholesterol.

The term "fat but fit" refers to the alluring theory that if people are obese but all their other metabolic factors such as blood pressure and blood sugar are within recommended limits then the extra weight will not be harmful. They noted that compared to a normal weight person without metabolic abnormalities, an obese individual with three metabolic abnormalities had a 2.6 times increased risk of coronary heart disease, a 58 percent increased risk of cerebrovascular disease, including strokes, a 3.8 times increased risk of heart failure as well as a 2.2 times increased risk of PVD. They had a 7 per cent increased risk of cerebrovascular disease - problems affecting the blood supply to the brain - which can cause a stroke, and double the risk of heart failure.

Overweight people who fall into the obese category have an increased risk of stroke and nearly double the risk of heart failure, the research found.

Commenting on the findings of the research, lead author of the study Dr Rishi Caleyachetty said that the study suggests that health professions need to change their approach when it comes to handling obesity cases. They analyzed the risk of developing coronary heart disease, cerebrovascular disease -which could be a stroke or a transient ischemic attack-, heart failure or peripheral vascular disease.

The idea of people being fat but fit is nothing more than a myth, health experts have discovered.

A new study has found that "metabolically healthy" obese people are still at higher risk of cardiovascular disease.

There is a point that weightlifters could be healthy and yet have a BMI that suggested they were obese.

While there was an overall lower risk of peripheral vascular disease, "healthy" obese people who never smoked still had an increased risk.

While Tam Fry, chairman of the National Obesity Forum, said: 'Can you be fat and fit?

'These people have the ability to store large amounts of fat around their bodies yet remain fit. Ask any group of rugby forwards who shift their bulk up and down a 100m field for 80 minutes and you'll get a "yes". And so the debate rages on'.

A summary of their study was discussed at the European Congress on Obesity.
