Have you ever encountered someone who calls themself ‘fat but fit’? It’s not uncommon to meet people who are clearly overweight, yet not perturbed by their situation because they consider themselves to be fit and healthy. However, a large study conducted in America has found that women who are overweight or obese but otherwise healthy are still at an increased risk of cardiovascular disease (CVD). For the study, researchers from the German Institute of Human Nutrition Potsdam-Rehbruecke tracked the health of some 90,257 women in the US over a 30-year period. They found that women who were overweight or obese, but had none of the typical cardiovascular risk factors, such as high blood pressure, excess cholesterol and diabetes, were 20% and 39% more likely to develop cardiovascular disease than their normal weight and metabolically healthy peers. Speaking about the findings of the study, Prof Matthias Schulze, who led it, said: "Our large cohort study confirms that metabolically healthy obesity is not a harmless condition, and even women who remain free of metabolic diseases for decades face an increased risk of cardiovascular events.” The study also found women who were of normal weight, but metabolically unhealthy, were over two-times more likely to develop cardiovascular disease than their peers of the same weight who were metabolically healthy. Jeremy Pearson, associate medical director at the British Heart Foundation, added: "This large scale study confirms that obesity, even if unaccompanied by other warning signs, increases risk of cardiovascular disease in women."
People who are overweight or obese, despite appearing medically healthy, are still at increased risk of heart disease, experts warn. The notion that people can be ‘fat but fit’ is being challenged by research published in the European Heart Journal. According to the researchers from Imperial College London and the University of Cambridge, who studied health data relating to more than half a million people in 10 European countries, weight is still a heart disease risk factor even if someone has normal blood pressure, cholesterol and blood sugar levels. The study found that people who appeared healthy, with healthy blood pressure, cholesterol and blood sugar readings, were still 28% more likely to develop heart disease than individuals with health bodyweights. Even more at risk were people who were overweight or obese and had high blood pressure, cholesterol and blood sugar levels. Dr Ioanna Tzoulaki, from Imperial's School of Public Health, said: "I think there is no longer this concept of healthy obese. "If anything, our study shows that people with excess weight who might be classed as 'healthy' haven't yet developed an unhealthy metabolic profile. "That comes later in the timeline, then they have an event, such as a heart attack”. So the advice if you want to maintain a healthy heart is to watch your weight, even if you think you are fit.
