Recognizing obesity as an important issue, two new studies researching weight loss have come up with interesting finds.
An American study has determined that when it comes to body-fat distribution, dieting and exercising have the same effect. The researchers from Pennington Biomedical Research Center in Baton Rouge, Los Angeles, concluded this after conducting a trial on 35 overweight participants. The trial participants were divided into three groups on the basis of a diet they had to follow for six months. The first group reduced calorie intake by 25 per cent while the second group embarked on a combination of a diet and exercise plan. The third group was the control group, which maintained its weight. At the end of the trial, the researchers observed that the distribution of body fat was the same for the first two groups. The findings of the study are in direct contrast to the belief that certain exercises can reduce fat in specific areas of the body. Though the weight loss achieved is the same whether one diets or combines diet and exercise, the researchers advocate the combination as exercise offers other health benefits for overall health.
Meanwhile, American researchers have found a weight loss supplement to have adverse side effects. Researchers from Ohio State University studied the effects of the supplement conjugated linoleic acid (CLA) on mice and rats. The mice lost weight quickly but simultaneously excessive fat got collected in their livers. Such collection could lead to insulin resistance. On the other hand, rats taking CLA failed to lose the weight they had gained before taking the supplement. Instead, they lost the extra fat from their livers. To better understand the effect CLA has on humans, the researchers are now looking at clinical trials that observe the effects of CLA on women with diabetes.
