In an article in the journal Archives of Internal Medicine recently, scientists found, the health of obese people depend on where the fat stored in the body. In normal people, and fat, abdominal fat is more higher risk of heart disease and diabetes compared with fat in the buttocks or thighs.
But for people with obesity, the greatest risk due to the accumulation of fat in the liver.
In one study, researchers at the University of Tübingen, Germany, studied 314 patients and divided into four groups: normal weight, overweight, obese but insulin-sensitive, and obese with insulin resistance.
Experts found that not all obese patients have the same health profile. Some have clogged arteries, which is a risk factor for heart attacks as well as insulin resistance which is a precursor to diabetes. Currently, the body loses sensitivity to the hormone that regulates blood sugar.
But about 25 percent of obese people have clean arteries and insulin resistance. From the medical side, these people are no different than the owner of normal weight.
"No one would say overweight healthy," said Lewis Landsberg, MD, of Northwestern University's Center on Obesity in Chicago. "The message is overweight is much healthier for some people than others," he was quoted Health.com
The big difference between obese patients and their colleagues are related to unhealthy accumulation of fat in the liver. Insulin-resistant obese people have more liver fat levels than almost doubled (8.8 percent) than people with normal weight (3.5 percent).
For comparison, normal weight and obese people have fatty liver levels respectively 1.9 percent and 3.8 percent.
