CTRE Trial Summary

This trial will study how meal timing relative to our natural body clock affects our health & weight. They hope to find if an intervention can help improve cardiometabolic health & weight.

Who is the study for?
This trial is for healthy adults who are overweight or obese with a BMI of at least 27. Participants should not have cardiovascular diseases, uncontrolled hypertension, diabetes, or a history of significant drug/alcohol use. They must be non-smokers without irregular work hours in the past year and no major travel recently.Check my eligibility
What is being tested?
The study examines if eating according to one's circadian rhythm can improve heart health and aid weight loss. Overweight individuals will follow a specific meal schedule for 46 days while researchers track changes in their cardiometabolic health both at home and in the lab.See study design
What are the potential side effects?
Since this intervention involves dietary timing rather than medication, side effects may include hunger outside of eating windows, potential headaches or irritability due to changes in meal patterns, but no medicinal side effects are expected.

Why did patients apply to this trial?

I gained a lot of weight during COVID and I think a big part of it was that my sleep schedule was very off due to my work situation and I was staying up until 4am or sometimes later. So I was eating late and I know everything was really off.
