Circadian Time Restricted Eating for Cardiometabolic Health and Weight Loss
This study is looking into how the timing of your meals, specifically a personalized schedule called Circadian Based Time Restricted Eating, affects your heart health (cardiometabolic health) and weight. Researchers want to see if eating at certain times based on your body's natural clock can improve these areas. You might be able to join if you are between 18 and 40 years old, are overweight or obese (BMI of 27 or higher), and are generally healthy. The study will measure changes in your blood pressure and heart rate over 46 days to see if the intervention is successful. The current status of the study is unclear.
- Study design
- This is an interventional study with a planned enrollment of 10 participants. It is a 46-day prospective cohort study.
- What's involved
- You would participate in a 46-day study that includes both field and in-laboratory data collection. You would follow a personalized eating schedule.
- Compensation
- Not stated in the trial record.
- Follow-up
- Changes in blood pressure and heart rate are measured at 46 days.

What this trial measures
- Dim-Light Melatonin Onset7.5 hours
Saliva samples will be collected during baseline week and will be assayed for melatonin using standardized assays. Dim-light melatonin onset will be calculated using the linear interpolated point in time in which each participant's melatonin crosses and remains elevated above a 4pg/mL threshold.
- Changes in Blood Pressure46 days
Changes in resting blood pressure will be measured every \~30 minutes via ambulatory blood pressure machines for up to 48-hours during weeks 0, 1, 5, 10, and 16. Blood pressure patterns during the day and night will be assessed, as well as a contrast of day and night time blood pressure levels. Examined using planned comparison dependent t-tests between the baseline and the five-week visit. These data will be used to calculate mean differences and standard deviations between the control and experimental group for future experiments.
- Changes in Heart Rate46 days
Heart rate will be measured every \~30 minutes via a blood pressure cuff. Examined using planned comparison dependent t-tests between the baseline and the five-week visit. These data will be used to calculate mean differences and standard deviations between the control and experimental group for future experiments.
- Changes in Hemoglobin A1c46 days
Changes in Hemoglobin A1c (HbA1c) will be measured during weeks 1, 5, and 16. Examined using planned comparison dependent t-tests between the baseline and the five-week visit. These data will be used to calculate mean differences and standard deviations between the control and experimental group for future experiments.
- Changes in Total Cholesterol46 days
Changes in total cholesterol will be measured during weeks 1, 5, and 16. Examined using planned comparison dependent t-tests between the baseline and the five-week visit. These data will be used to calculate mean differences and standard deviations between the control and experimental group for future experiments.
- Changes in LDL and HDL cholesterol46 days
Changes in HDL and LDL cholesterol will be measured during weeks 1, 5, and 16. Examined using planned comparison dependent t-tests between the baseline and the five-week visit. These data will be used to calculate mean differences and standard deviations between the control and experimental group for future experiments.
- Changes in Triglycerides46 days
Changes in triglycerides will be measured during weeks 1, 5, and 16. Examined using planned comparison dependent t-tests between the baseline and the five-week visit. These data will be used to calculate mean differences and standard deviations between the control and experimental group for future experiments.
- Changes in Glucose46 days
Changes in glucose will be measured during weeks 1, 5, and 16. Examined using planned comparison dependent t-tests between the baseline and the five-week visit. These data will be used to calculate mean differences and standard deviations between the control and experimental group for future experiments.
