About

The purpose of this research study is to evaluate the effects of intermittent fasting in subjects that are eating a Mediterranean diet or a Western diet. This study is part of ongoing research in the prevention and treatment of age-related diseases at Washington University School of Medicine.

Full description

The primary objective of this study is to determine whether or not IF, independently of changes in quality of diet, reduces the level of chronic inflammation as evidenced by a decrease in high sensitivity C-reactive protein (hsCRP), as the main outcome measure.

Ages: 30 to 65 years old

Volunteers: Accepts Healthy Volunteers
