Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to see if reducing the number of hours during which one eats each day will help reduce levels of LDL cholesterol and improve other markers of metabolic and cardiovascular health (i.e. blood sugar levels and blood pressure). The study also aims to assess changes in exercise capacity and trimethylamine N-oxide (TMAO) levels in response to Time Restricted Eating (TRE) and Intensive Cardiac Rehabilitation (ICR) versus ICR alone. TMAO is a metabolite, or a substance, produced during digestion and metabolism. Preliminary data illustrates a correlation between high levels of TMAO and higher risk of cardiovascular disease and mortality. We will also be looking at participants' long-term cardiovascular health status after they complete the ICR program.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

ICR (Intensive Cardiac Rehabilitation)

20 patients will be randomly assigned to the standard of care group, which will receive the standard health and nutritional wellness guidelines that are required of UCSD's 9-week ICR program, referred to as the "ICR" group.

Group Type PLACEBO_COMPARATOR

ICR (Intensive Cardiac Rehabilitation)

Intervention Type BEHAVIORAL

Participants in this arm will not have to adopt a 10-hour eating window while taking part in UCSD's 9-week ICR program.

ICR x TRE (Intensive Cardiac Rehabilitation x Time-Restricted Eating)

20 patients will be randomly assigned to the Time-Restricted Eating (TRE) group which will be asked to limit the number of hours they eat in a day to 10 hours in addition to receiving the standard of care health and nutritional wellness guidelines that are required of UCSD's 9-week ICR program, referred to as the "ICR x TRE" group.

Group Type EXPERIMENTAL

ICR x TRE (Intensive Cardiac Rehabilitation x Time-Restricted Eating)

Intervention Type BEHAVIORAL

Participants in this arm will adhere to a daily, consistent 10-hour eating window while undergoing UCSD's 9-week ICR program to see if there is an improvement on cardiometabolic parameters.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

19. History of HIV/AIDS.
20. Currently enrolled in a weight-loss or weight-management program. This does not include UC San Diego's Cardiac Rehabilitation Programs.
21. On a special or prescribed diet for other reasons (e.g. Celiac disease).
22. Currently taking any medication that is meant for, or has a known effect on, appetite.
23. Any history of surgical intervention for weight management.
24. Uncontrolled psychiatric disorder (including history of hospitalization for psychiatric illness).
25. Baseline eating window \<14 hours per day as documented on mCC app.
26. Failure to use the smartphone app for documentation (defined as \<2 meals/day for ≥3 days during baseline).
