In recent years, many rich as well as some poor countries have seen a massive rise in ‘metabolic syndrome’, the symptoms of which include insulin resistance, high blood cholesterol and an increased risk of diabetes, heart disease and stroke. The International science magazine, New Scientist reports that this syndrome is said to be linked with obesity but how exactly is it linked with the conditions of obesity is not clear.
Roger Unger and Philipp Scherer at the University of Texas Southwestern Medical Center in Dallas reviewed several recent studies related to the role of fat cells in humans and mice, to determine the effects of obesity. The two looked at the fates of people with a genetic condition and concluded that they can’t make their own fat cells. Also, genetically engineered mice were fed a diet that would make normal mice obese as they have low supplies of fat cells. They found that both had a greater propensity to develop metabolic syndrome as compared to their overweight, overfed counterparts.
The study, published in Trends in Endocrinology and Metabolism, concluded that obesity protects the body from the effects of overeating by providing a safe deposit to the dietary deluge of fat and sugar, the excess of which can prove toxic for many body tissues.
