NCT ID NCT07560579

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

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.

Summary

This study looks at whether reducing exposure to everyday chemicals called endocrine disruptors (found in plastics, cosmetics, and food) can help people with overweight or obesity lose weight. About 226 participants will either follow a program to lower chemical exposure or use a standard weight loss app. Researchers will measure weight changes and chemical levels in urine and blood to see which approach works better.

What this could mean

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

Active substance
Educational curriculum on reducing EDC exposure and a weight loss application
What this could lead to
If successful, this could show that reducing everyday chemical exposures helps people lose weight, pointing toward new weight management strategies.
What could go wrong
This is an early-stage study with no blinding, and results may not apply to everyone. The interventions are behavioral, so outcomes depend heavily on participant adherence.
