TREMBO Trial Summary

This trial will study the effect of time-restricted eating and calorie restriction on body weight, gut bacteria, and bone health in overweight/obese older women.

Who is the study for?
This trial is for postmenopausal women who are overweight or obese, with a BMI of 25-39 kg/m2 and eat over a span of at least 14 hours daily. They must be able to visit the site in New Brunswick, NJ without travel reimbursement. Women taking certain bone medications, those with recent significant weight loss or extreme diets, smokers, and those with various health conditions including uncontrolled hypertension cannot participate.Check my eligibility
What is being tested?
The TREMBO study is testing if eating within a set time frame each day plus cutting calories helps older women lose weight better than just cutting calories alone. It also looks at how this might affect the good bacteria in their guts and their bone health.See study design
What are the potential side effects?
Potential side effects from participating may include feelings of hunger due to calorie restriction and changes in energy levels or mood related to new eating patterns.

2Treatment groups
Experimental Treatment
Active Control
Group I: Time restricted eating and calorie restrictionExperimental Treatment2 Interventions
Subjects will be asked to adhere to a calorie-restricted diet and will be counseled by a dietitian for diet and lifestyle behavior education. In addition, they will be asked to only consume calories during a 9-hour window (15:9).
Group II: Calorie restriction aloneActive Control1 Intervention
Subjects will be asked to adhere to a calorie-restricted diet and will be counseled by a dietitian for diet and lifestyle behavior education. They will be advised to continue to consume foods throughout the day and into the evening.

Other Research
Time-restricted eating (TRE) is a weight loss strategy that involves limiting food intake to specific hours of the day, which can improve metabolic health by aligning eating patterns with the body's circadian rhythms. This approach can enhance insulin sensitivity, reduce appetite, and promote fat loss. Additionally, TRE may positively influence the gut microbiota by fostering a more balanced microbial environment, which can further support metabolic health. For weight loss patients, these mechanisms are crucial as they not only aid in reducing body weight but also improve overall metabolic function and potentially bone health, making TRE a holistic approach to weight management.
