Clinical Trial Summary

Participants will be randomly assigned to either the time restricted feeding group with a daily eating period of 8 hours or the control group with a daily eating period of greater than or equal to 12 hours. There are 2 in-person study visits to have blood, urine and vital signs collected and 8 remote or phone visits with a psychologist or dietician to assist with the eating schedule. The study will take last 3 1/2 months.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Advanced Glycation End Products (AGE) as assessed by plasma	Estimated mean levels within the intervention and the control groups of the study. Effect size will be estimated via 95% confidence intervals within and between groups.	Visit 1 and Visit 2 approximately 12 weeks
Primary	Change in sRAGE(soluble receptor for AGE) levels	Estimated mean levels within the intervention and the control groups of the study. Effect size will estimated via 95% confidence intervals within and between groups. .The intervention and control groups of AGE and sRAGE levels will be used to determined AGE by sRAGE ratio	Visit 1 and Visit 2, approximately 12 weeks
Primary	Assess feasibility and adherence to time period of eating recommendations in both study groups.	Proportion of days that time period of eating was followed.	Visit 1 and Visit 2, approximately 12 weeks
Secondary	Change in Fasting insulin-like growth factor-1 (IGF-1) levels	Estimated mean levels within the intervention and the control groups of the study. Effect size will be estimated via 95% confidence intervals within and between groups.	Visit and Visit 2, approximately 12 weeks
Secondary	Change in Fasting insulin levels	Estimated mean levels within the intervention and the control groups of the study. Effect size will be estimated via 95% confidence intervals within and between groups.	Visit 1 and Visit 2, approximately 12 weeks
Secondary	Difference in Glasgow Prognostic Scoring System	The Glasgow Prognostic Score (GPS) reflects systemic inflammatory process. Difference within groups and between groups of the cumulative inflammation-based cancer-prognostic marker. GPS is a three-tiered score [0: normal C-reactive protein (CRP) and albumin; 1: one abnormal result; 2: increased CRP and low albumin]. Higher score means worse outcome.	Visit 1 and Visit 2, approximately 12 weeks
Secondary	Change in 24 hour urinary AGE levels	Estimated mean levels within the intervention and the control groups of the study. Effect size will be estimated by the 95% confidence intervals within and between groups.	Visit 1 and Visit 2, approximately 12 weeks
Secondary	Adherence to virtual visit with psychologist or dietician	Number of participants in the intervention and control group that completed virtual visits with the psychologist.	Visit 1 and Visit 2, approximately 12 weeks
Secondary	Adherence to time period of eating recommendation in both study groups: self reporting during virtual visits and through food photography / annotated entries.	Proportion of days that time period of eating was followed.	Visit 1 and Visit 2, approximately 12 weeks
Secondary	Time restricted feeding affected sleep patterns	Change in sleep pattern between intervention and control groups as assessed using American Academy of Sleep Medicine 2 week sleep diaries.	Visit 1 and Visit 2, approximately 12 weeks
Secondary	Peripheral blood mononuclear cell (PMBC) analysis	Peripheral blood mononuclear cells will be analyzed for RAGE expression and compared within and between intervention and control groups.	Visit 1 and Visit 2, approximately 12 weeks
Secondary	Continuous Glucose Monitor (CGM) derived metrics	Mean glucose, standard deviation (SD) of mean glucose values, co-efficient of variation (CV %) of sensor glucose levels, glucose management indicator (GMI%) from CGM data. Estimated mean levels within the intervention and the control groups of the study. Effect size will be estimated by the 95% confidence intervals within and between groups.	Visit 1 and Visit 2, approximately 12 weeks
