Dr. Courtney Peterson is an internationally-recognized researcher in the field of intermittent fasting. Her research focuses on daily intermittent fasting, which is also known as time-restricted eating. Dr. Peterson conducted the first controlled feeding trial of intermittent fasting in humans and was the first to test early time-restricted eating (eTRE) in humans, a version of TRE that involves eating early in the day to be in alignment with circadian rhythms in metabolism. Her research established that eTRE can improve insulin sensitivity, glucose levels, blood pressure, and oxidative stress, even in the absence of weight loss. She also demonstrated that eTRE does not affect energy expenditure but does affect fat oxidation, metabolic flexibility, and appetite hormones, including ghrelin, leptin, and PYY. Further, her research has established that eTRE affects molecular pathways involved in longevity and autophagy. Currently, she is the PI, MPI, or site PI of seven clinical trials on time-restricted eating and serves as a co-investigator or consultant on another five clinical trials. She currently is the PI of the largest randomized controlled trial of intermittent fasting in humans—a 344-person study in adults with type 2 diabetes. As secondary interests, she also performs mathematical modeling of body composition and metabolic data. For instance, her research showed that the tri-ponderal mass index better estimates adiposity in adolescents than BMI. Her research has been featured in more than 50 media outlets, including NBC Nightly News, The New York Times, The Washington Post, Wall Street Journal, Good Morning America, the BBC, and Scientific American, and has reached a circulation of more than 104 million people around the world.
