ClinConnect Summary

The Daily Eating Patterns for Total Health Study is a clinical trial aimed at understanding how the timing of meals can affect long-term weight loss, particularly in people with obesity. The researchers want to see if eating most calories in the morning or evening makes a difference in how much weight participants lose over a year. They will also look at how these eating patterns affect sleep, appetite, and overall eating habits.

To participate, individuals need to have a body mass index (BMI) between 27 and 45. Participants will follow a reduced-calorie, low-fat diet, try to be physically active for at least 200 minutes a week, and receive support through a behavioral program. It's important to note that certain health conditions or medications that affect eating or sleep might prevent someone from joining the study. Participants will be recruited from a wide age range, and everyone will have the chance to contribute to valuable research on weight management.
