How timing of food intake affects weight loss in obesity treatment.
Official title: Effect of time-based energy intake goals on weight loss during obesity treatment.
Funded at University of Tennessee Knoxville · NIH-11009565 · Data updated 2026-11-12
This study is looking at how when you eat during the day can help you lose weight if you're working on managing obesity, and it will show you how to plan your meals to eat more earlier in the day for better results.

Who could benefit from this research
✓Could help
Ideal candidates for this research are adults aged 21 and older who are seeking to lose weight and manage obesity.
✕Less likely to help
Patients who are not overweight or obese may not receive any benefit from this research.
What this research studies
This research investigates how the timing of energy intake throughout the day can influence weight loss in individuals undergoing obesity treatment. By focusing on time-based dietary goals, the study aims to synchronize biological and behavioral circadian rhythms, potentially enhancing appetite regulation and promoting weight loss. Participants will be guided on how to distribute their caloric intake, with an emphasis on consuming more calories earlier in the day. The study will assess the long-term effects of this approach on weight loss and appetite control.
Why it matters
Potential benefit: If successful, this research could lead to more effective weight loss strategies for individuals struggling with obesity.
How similar studies have gone: Previous research has shown promising results with time-based dietary interventions, although long-term effects remain largely unexplored.
