A study at Washington University School of Medicine in St Louis has suggested that obesity may not always cause someone to have metabolic changes.
It found that there was a subset of obese people who do not have metabolic abnormalities, which are common among those who are carrying excess weight and puts them at a higher risk of suffering a stroke or developing diabetes.
Published in the Journal of Clinical Investigation, the study also found that these obese people who didn't have these metabolic problems when the study began did not develop them even after they gained more weight.
The study involved 20 obese participants who were asked to gain about 15 pounds over a number of months to determine how the extra weight would affect their metabolic functions.
"This research demonstrates that some obese people are protected from the adverse metabolic effects of moderate weight gain, whereas others are predisposed to develop these problems," said senior investigator Dr Samuel Klein, the Danforth professor of Medicine and Nutritional Science and director of Washington University's Center for Human Nutrition.
