Strengthening Circadian Signals for Improving Cardiometabolic Outcomes in Adults

Q: How many individuals have elected to participate in this experiment?

Indeed, the data hosted on clinicaltrials.gov conveys that this medical study is actively recruiting patients. It was initially posted in May of 2018 and most recently revised on November 15th 2022; with a goal to enroll 100 people from 1 site.

Q: Is there still availability for participants in this investigation?

That is correct. According to the information on clinicaltrials.gov, this medical trial has been active since May 16th 2018 and its last update was November 15th 2022. The experiment seeks out 100 participants from 1 designated site.

Q: Are adults aged 18 and above eligible to become participants in this research?

According to the protocol laid out in this trial's eligibility criteria, potential participants must be aged between 35 and 54.

Q: Am I eligible to sign up for this medical experiment?

The current study seeks to recruit 100 individuals aged 35-54 who have improved cardiometabolic outcomes. To be eligible, participants must also abide by a regular eating schedule with two meals daily and <a href="https://www.withpower.com/clinical-trials/sleep">sleep</a> patterns that include an overnight fast of 13 hours or less over three days and no more than nine hours in bed. Furthermore, the average self-reported duration of slumber should exceed 6.5 hours while habitual mid sleep time is best between 2am - 5am.

Experimental Treatment

Placebo Group

Group I: MelatoninExperimental Treatment2 Interventions

This arm will continue to eat at their habitual meal times, and maintain their average habitual caloric and macronutrient intake. No extended overnight fasting will be imposed. This arm will include a 1mg melatonin supplementation given daily during the intervention.

Group II: Meal timing + PlaceboExperimental Treatment2 Interventions

This arm will consist of imposing a minimum overnight fasting period of 12 hours and a maximum of 16 hours (with exception of water and other non-caloric beverages), beginning 3 hours before their habitual bed time. This arm will also include a melatonin placebo (lactose) supplementation given daily during the intervention.

Group III: Meal timing + MelatoninExperimental Treatment2 Interventions

This arm will consist of imposing a minimum overnight fasting period of 12 hours and a maximum of 16 hours (with exception of water and other non-caloric beverages), beginning 3 hours before their habitual bed time. This arm will also include a 1mg melatonin supplementation given daily during the intervention.

Group IV: PlaceboPlacebo Group2 Interventions

This arm will continue to eat at their habitual meal times, and maintain their average habitual caloric and macronutrient intake. No extended overnight fasting will be imposed. This arm will also include a melatonin placebo (lactose) supplementation given daily during the intervention
