Study Details

Brief summary:

Participants will complete a one-month intervention where they are will restrict their daily food intake to an 8-hour time period, i.e., between 1200 to 2000 hours. During the remaining 16-hour intermittent fasting period (2000 to 1200 hours) participants will be allowed to drink zero calorie beverages (diet soda pop, black coffee, tea, water, etc) in order to maintain normal hydration. There will be no attempt to restrict food intake. Rather simply to restrict the time period each day when food is consumed. Participants' body mass, fat mass, and non-fat mass will be monitored non-invasively using a weigh scale and densitometry via air displacement (Bod Pod) at 0, 2 and 4 weeks following the dietary intervention. Also, participants will be interviewed following the final body composition measure to assess whether or not they continued to follow the intermittent fasting approach.
