Trial Summary

What is the purpose of this trial?

This is a randomized, parallel two-arm clinical trial design to study the efficacy of time-restricted feeding on metabolic risk in postmenopausal women, who may be particularly vulnerable to disruption of circadian eating rhythms and the associated metabolic dysfunction. It is hypothesized that time-restricted feeding will improve insulin sensitivity, glucose tolerance, body weight, and other metabolic parameters in metabolically-unhealthy postmenopausal women.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, if you are on hormone therapy or ADHD medications, you would not be eligible to participate.

What data supports the effectiveness of the treatment Time-Restricted Eating for Metabolic Syndrome in Postmenopausal Women?

Research shows that time-restricted eating (TRE) can help improve weight, blood pressure, and cholesterol levels in people with metabolic syndrome. Studies have found that TRE can enhance cardiometabolic health, even when combined with standard medical treatments like statins and blood pressure medications.12345

Is time-restricted eating safe for humans?

Time-restricted eating (TRE) has been studied in humans and is generally considered safe, with research showing it can improve weight, blood pressure, and other health markers in people with metabolic syndrome and obesity.12678

How is the treatment Time-Restricted Eating different from other treatments for metabolic syndrome?

Time-Restricted Eating (TRE) is unique because it focuses on limiting the time window for eating each day, rather than changing what or how much you eat. This approach can improve metabolic health by aligning eating patterns with the body's natural circadian rhythms, potentially enhancing the effects of standard medications like statins and blood pressure drugs.12346

Interventions

  • Time-Restricted Feeding (Behavioral Intervention)
Trial OverviewThe study is testing if eating within a set time frame each day (time-restricted feeding) can improve health markers like blood sugar control and body weight in metabolically-unhealthy postmenopausal women. Participants will be randomly assigned to one of two groups to compare the effects.
Participant Groups
2Treatment groups
Experimental Treatment
Active Control
Group I: Time-Restricted Feeding (TRF) GroupExperimental Treatment1 Intervention
Participants in this group will have baseline and post-study data collected, including food timing, activity/sleep data, and metabolic parameters (OGTT, body composition, anthropometric measurements, lipid panel, inflammatory markers). Subjects in this group will be educated about the health benefits of time-restricted feeding (TRF). Then each subject in the TRF group will self-select a 10-h window during which she will consume all daily calories for 16 weeks.
Group II: ControlActive Control1 Intervention
Participants in this group will have baseline and post-study data collected, including food timing, activity/sleep data, and metabolic parameters (OGTT, body composition, anthropometric measurements, lipid panel, inflammatory markers). There will be no intervention.

Findings from Research

In a study involving 19 participants with metabolic syndrome, a 12-week time-restricted eating (TRE) intervention improved cardiometabolic health, suggesting it can be an effective lifestyle change alongside standard medical treatments.
The majority of participants were already on medications like statins and antihypertensives, indicating that TRE may work synergistically with pharmacotherapy to enhance health outcomes in patients with metabolic syndrome.

The TREMNIOS pilot clinical trial aims to assess the feasibility of a 10-hour time-restricted eating (TRE) intervention over 12 weeks in Polish adults with metabolic syndrome, focusing on its effects on various health biomarkers and daily behavior rhythms.
This study will utilize validated monitoring tools and aims to establish a foundation for a larger randomized controlled trial to evaluate the efficacy of TRE in improving cardiometabolic health in individuals with metabolic syndrome.

Time-restricted eating (TRE) shows promise in improving cardiometabolic health in individuals with metabolic syndrome (MetS) by aligning eating patterns with circadian rhythms, potentially mitigating risks associated with obesity, diabetes, and cardiovascular disease.
Pilot studies have indicated that TRE can lead to significant improvements in body weight, abdominal obesity, and blood pressure without requiring changes in diet quality or physical activity, highlighting its potential as a simple intervention for MetS.

Time restricted eating as a weight loss intervention in adults with obesity.Przulj, D., Ladmore, D., Smith, KM., et al.[2021]
In a study of 36 women with overweight or obesity, those following an 8-week time-restricted eating (TRE) plan experienced greater weight loss and reductions in body fat compared to a non-TRE group, despite both groups following a caloric restriction diet.
The weight loss observed in the TRE group was not linked to changes in resting metabolic rate or improvements in mood or eating disorder symptoms, suggesting that TRE can be effective for weight loss without affecting these behavioral factors.
