Reducing the size of abdominal fat cells – which are a risk factor for diabetes and heart disease – takes more than cutting calories// , according to new research from Wake Forest University Baptist Medical Center. Early results from a five-year study show that exercise should be added to the equation.
“The message is very clear,” said Tongjian You, Ph.D., instructor in geriatric medicine at Wake Forest Baptist and lead author. “Exercise is important to reducing the size of these cells, and may one day be part of a prescription for treating the health complications associated with abdominal fat.”
The study is reported in the August issue of the International Journal of Obesity. The results – from 45 obese, middle-age women with excess abdominal fat – are part of an ongoing study of up to 125 women. The goal is to determine what lifestyle changes are needed to reduce the size of abdominal fat cells.
It is well known that overall obesity is a risk factor for diabetes and heart disease. Not all obese people develop these diseases, of course. Obese people who have more abdominal fat (an apple shape) are at a higher risk than people who store excess fat in their hips and thighs (a pear shape).
Abdominal fat is associated with metabolic syndrome, a cluster of symptoms that increases the risk for heart disease and diabetes. The syndrome is diagnosed when someone has at least three of the following: abdominal obesity, high triglycerides, low levels of high-density liprorotein (“good”) cholesterol, high blood pressure and increased levels of sugar in the blood.
The current research studied a lesser-known risk factor for the syndrome – the size of fat cells just under the surface of the skin, known as subcutaneous fat.
“The size of these fat cells predicts type 2 diabetes, independent of whether the patient is obese,” said You.
