A new study has found that many overweight people, who otherwise seem healthy, have an unhealthy rise in blood pressure and several other metabolic risk factors over a period of 20 years.
According to the researchers, most ‘healthy obesity’ transforms into ‘unhealthy obesity’ with the passing time.
Detailing about the study’s findings, lead author Joshua A. Bell, from University College London, said, “These results were not overly surprising as we already know that healthy obese adults have a higher risk for developing cardiovascular disease (CVD) and type 2 diabetes than healthy normal-weight adults.”
Many previous studies showed that about a third of healthy obese people transformed into unhealthy obesity over time, Bell said. For the new study, the researchers tracked people for a period of at least 10 years longer than several previous studies. The new study showed that this tendency started getting stronger with time as about half of the participants making this transition after 20 years.
In the study, the researchers used data from an ongoing research work that involved more than 2,500 civil servants from the UK, with the health metrics gathered every five years.
The researchers said that the healthy obesity is often just a phase.
The study’s findings have been reported in the Journal of the American College of Cardiology.
