According to a US study: even a little bit of extra weight can raise the risk of heart failure that calculated the heart hazards of being pudgy but not obese. It comes obesity makes a person much more apt to get heart failure, a deadly condition which the heart is unable to pump enough blood throughout the body.
But researchers tracked the health of 21,094 male doctors for two decades found that even those who were only modestly overweight had a higher risk & it grew along with the amount of extra weight.
In men who are 5 feet 10 inches tall, for every seven pounds (3.2 kg) of excess body weight, their risk of heart failure rose on average by 11% over the next 20 years.
The average age of the men at the outset of the so called Physicians' Health Study was 53. Overall, the risk of heart failure increased by 180% in men who met the definition of obesity according to their body mass index (BMI of 30 and higher), and by 49 percent in men who met the definition of overweight (a BMI of 25 to 30).
Heart failure known as congestive heart failure, contributes to 300,000 deaths each year. The lean and active group had the lowest risk and the obese and inactive group had the highest risk. As far as vigorous physical activity is concerned, even if somebody said they exercised one to three times per month which is a very low level of exercise they had an 18% reduction in the risk of heart failure after accounting for all other established risk factors.
The benefit of exercise in cutting heart failure risk was seen in lean, overweight and obese men, the researchers found. But regardless of the level of activity, higher body mass index also meant higher heart failure risk.
