Dietary Approaches for Cardiometabolic Health

Dietary Approaches for Improving Cardiometabolic Health

This pilot study aims to recruit 30 adults with abdominal obesity, without major chronic disease, and test whether clinical dietary advice that is solely focused on the timing of eating (time restricted eating), has an effect on cardiometabolic health compared to standard dietary advice for cardiometabolic health, which is focused on content. The goal of this pilot study is to develop and hone dietary counseling approaches for time restricted eating for RD's in a clinical practice paradigm, and collect data on testing this intervention compared to standard dietary counseling approaches for cardiometabolic health.
