BOONE, N.C. — Does ingesting a combination of caffeine and flavonoids boost a woman’s resting metabolic rate? A $89,214 grant to Appalachian State University’s Dr. David Nieman may find out.
Nieman, a professor in the Department of Health and Exercise Science, along with Drs. Jennifer McBride and Jomari Torres, will conduct a clinical trial to evaluate the effects of ingesting a caffeine-flavonoid mixture on energy expenditure and fat oxidation in healthy adult women. This research is funded by Reoxcyn Discoveries Group Inc., which awarded Nieman with the grant.
McBride is a research scientist at the North Carolina Research Campus in Kannapolis who collaborates with the Beaver College of Health Sciences’ Department of Health and Exercise Science, and Torres is the human research core medical director at the University of North Carolina at Chapel Hill Nutrition Research Institute.
Nieman said the purpose of the team’s research is to “measure the effect of ingesting four capsules containing 214 milligrams of caffeine and a variety of flavonoids (658 mg total), including green tea catechins and quercetin and bilberry anthocyanins, on an individual’s RMR and level of fat burning.”
Nieman explained the study will be accomplished by having participants stay in a specially equipped, small hotel-like room (called a metabolic chamber) for two separate days — one day consuming the caffeine-flavonoid capsules, and a second day consuming placebo capsules.
“Resting metabolic rate (RMR) or metabolism is defined as the calories an individual burns each day to keep alive during sleep and seated rest. If a person consumes 100 milligrams of caffeine or what is found in one cup of coffee, their RMR will increase about 11 calories per day,” according to Nieman.
He added, “Other molecules found in food called flavonoids can also increase RMR. For example, 100 milligrams of green tea catechins, or what is found in a small cup of brewed green tea, increases RMR by about 13 calories per day. Other flavonoids found in the skins of apples and onions (quercetin) and in berries (anthocyanins) may also increase RMR, but more research is needed.”
