What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published

Summary

This pilot study tested whether older adults with extra weight could stick to either eating fewer calories or eating only within an 8-hour window for 9 months. About 90 people took part, with some getting in-person coaching and others doing it remotely. The goal was to see if these diets are doable, not to measure health benefits yet.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
calorie restriction and time-restricted eating
What this could lead to
If successful, this could show that simple dietary changes are feasible for older adults and pave the way for larger studies on healthy aging.
What could go wrong
This is a small pilot study focused on feasibility, not health outcomes. Results may not apply to all older adults, and long-term effects are unknown.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

60 years and older

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Community-dwelling men and women residing in Forsyth County, NC or surrounding counties * obesity (BMI = 30 - \< =40 kg/m2) or are overweight (BMI = 27 - \<30 kg/m2 with an indication for weight loss (e.g., hypertension, hyperlipidemia, elevated waist girth, controlled diabetes) Exclusion Criteria: * persons for whom the interventions are potentially unsafe * history of eating or nutritional disorders * those who are likely to drop out due to severe chronic illness or other reasons * who show inability to perform self-monitoring activities required by the interventions * those doing shift work because disturbances in circadian cycles may interfere with TRE * uncontrolled or previously undetected diabetes because disease management may interfere with the interventions * certain medical treatments may complicate outcome interpretation
