Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Calorie Restriction Only
Participants in this group will be decreasing their caloric intake to approximately 95% of their resting metabolic rate. We will provide one meal for 4 days of the week, and participants will be required to keep an accurate dietary record of all food and drink. Participants assigned to this group will be instructed to keep a fixed sleep schedule based on their own sleep/napping habits.
Calorie restriction only
Participants randomly assigned to this group will be instructed to reduce their daily energy intake to 95% of their resting metabolic rate.
Sleep & Calorie Restriction
Participants in this group will decrease their caloric intake to approximately 95% of their resting metabolic rate in addition to reducing their total time in bed by 90 minutes 5 days a week.
Sleep & calorie restriction
Participants randomly assigned to this group will be instructed to reduce their total time in bed by 90 minutes 5 days a week, in addition to restricting their dietary intake to approximately 95% of their resting metabolic rate.
