The biggest concern of a weight watcher is to be identified as overweight or obese; while a small weight gain hardly evokes any concern. However, if a recent study is to be believed, gaining as little as 5 pounds (3 kg) can increase blood pressure even among normal weight individuals.
According to the study, presented at the American Heart Association’s High Blood Pressure Research Scientific Sessions 2014, the effect of a small weight gain on blood pressure seems to be further amplified if the fat deposition occurs around the stomach area.
The researchers used a 24-hour monitor to measure blood pressure in 16 normal weight individuals aged between 18 and 48 years at the beginning of the trial. Researchers fed them extra 400–1200 calories daily from their choice of foods such as ice cream shake, chocolate bar or energy drink to increase their body weight by about 5%. After a period of 8 weeks, another 24-hour measure of blood pressure was recorded and the results were compared to individuals who maintained the same weight.
They found that a weight gain of 5-11 pounds resulted in an increase of 4 mmHg of systolic blood pressure (from an average 114 to 118 mmHg). Those who gained abdominal visceral fat showed greater blood pressure increase. However, this small weight gain had no effect on insulin, blood sugar or cholesterol levels.
“The public awareness of the adverse health effects of obesity is increasing; however, it seems most people are not aware of the risks of a few extra pounds,” said a senior researcher Naima Covassin.
Most of the time, minimal weight gain during holidays or 1st year of college is not considered as a big issue. However, in light of these new findings, even a few extra kilos of weight gain in healthy individuals seem to impose health risks.
