Rutgers Evolutionary Anthropologist Erin Vogel thinks new research published in Biology Letters, a Journal of the Royal Society, examining how endangered Indonesian orangutans - considered a close relative to humans - survive during times of extreme food scarcity might help scientists better understand eating disorders and obesity in humans.All they are doing in describing Calories in vs. Calories out.
"There is such a large obesity epidemic today and yet we don't really understand the basis of the obesity condition or how these high-protein or low-protein diets work," said Vogel, whose research, Bornean orangutans on the brink of protein bankruptcy, represents the first time scientists have looked at how these long-haired, orange-colored apes - that depend on low-protein fruit to survive - endure protein cycling, or period bouts of protein deprivation. "I think studying the diets of some of our closest living relatives, the great apes; may help us understand issues with our own modern day diets," she said.
According to Vogel, an assistant professor of anthropology in Department of Anthropology and Center for Human Evolutionary Studies, in the School of Arts and Sciences, the research shows that it is only during high periods of high caloric and protein intake that orangutans put on fat, a scientific fact that is sometimes ignored by those who believe that high protein, low carbohydrate diets are the best way to lose weight. She said it is only when caloric intake is restricted that orangutans use these fat reserves for energy and eventually dip into their protein (muscle) reserves - a condition that is seen with eating disorders like anorexia.
No more, no less.
