New study finds that eating whole grains increases metabolism and calorie loss

BOSTON (Feb. 8, 2017)—A new study suggests that substituting whole grains for refined grains in the diet increases calorie loss by reducing calories retained during digestion and speeding up metabolism. This research is published in tandem with a study on the effect of whole grains on gut microbiota. Both studies are published today in the American Journal of Clinical Nutrition.

Epidemiology studies have suggested health benefits of whole grains and high dietary fiber intake, including for glycemic control and insulin sensitivity. There has been controversy, however, about whether whole grains and fiber are beneficial for weight regulation, partially because there hasn’t been data from controlled metabolic studies. This new study provided food to participants for eight weeks and may help explain how whole grain consumption is beneficial for weight management.

“Many previous studies have suggested benefits of whole grains and dietary fiber on chronic disease risk. This study helps to quantify how whole grains and fiber work to benefit weight management, and lend credibility to previously reported associations between increased whole grains and fiber consumption, lower body weight and better health,” says Phil J. Karl, PhD, first author of the study, alumnus of the Friedman School of Nutrition Science and Policy at Tufts, former research assistant in the Energy Metabolism Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University in Boston, and current nutrition scientist at the U.S. Army Research Institute of Environmental Medicine in Natick, MA.
