Obesity treatment could help to reduce the risk of heart attacks in the UK.
Recent research has revealed that total heart attack rates in London have fallen by 74 per cent over the last two decades.
Published in the European Heart Journal, the study attributed this decline largely to better control over hypertension and cholesterol, along with a decline in smoking.
However, the researchers from University College London Medical School noted that this decline could have been around 11 per cent greater if more had been done to lower the prevalence of obesity.
Senior research associate Sarah Hardoon commented: "Although these favourable trends seem to have outweighed the negative contribution of rising Body Mass Indexes (BMIs) over recent decades, continued increases in BMIs may reduce further and even reverse the decline in the incidence of heart attacks in the future.
"Therefore the rising BMI in the UK and in other countries needs urgent attention."
