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 This study
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
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 Results may not be published yet.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
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study uses a wearable glucose sensor and artificial intelligence to understand how healthy adults process sugar. Researchers will track blood sugar patterns for 14 days and link them to diet, activity, and health measures. The goal is to develop personalized nutrition tools that could help prevent type 2 diabetes and other metabolic issues.

What this could mean

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

Active substance
continuous glucose monitor (wearable sensor)
What this could lead to
If successful, this could lead to personalized dietary recommendations based on individual blood sugar patterns, helping to prevent type 2 diabetes and other metabolic diseases.
What could go wrong
This is an observational study that does not test a treatment. The AI algorithm may not accurately predict health outcomes, and results may not apply to everyone.

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

Who can take part

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

Who is studied

The study population consists of community-dwelling adults aged 18-70 years, recruited from the general population through public advertisements, university campus postings, pharmacies, and primary care centers. Participants represent a broad, non-clinical community sample without diagnosed diabetes or severe metabolic disease. Recruitment is open to individuals living independently and able to maintain their usual daily routines. The population reflects a heterogeneous mix of sociodemographic backgrounds to ensure variability in dietary habits, lifestyle patterns, and glucose-response profiles.

Ages

18 to 70 years

Sex

You do not need to have the condition being studied to take part.

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

Inclusion Criteria: * Adults aged 18 to 70 years. * Willing and able to undergo 14 days of continuous glucose monitoring (CGM) using a wearable sensor. * Able to maintain stable dietary habits during the monitoring period. * Able and willing to complete dietary records, including two structured 3-day food logs. * Able and willing to photograph all meals during the 14-day monitoring period following instructions provided. * Able to keep a record of physical activity as instructed. * No previous diagnosis of diabetes or other serious metabolic disorders. * Sufficient commitment and availability to attend all study visits (screening, baseline evaluation, final evaluation). * Capable of providing written informed consent. Exclusion Criteria: * Diagnosed diabetes mellitus or other serious metabolic disorders. * History of severe gastrointestinal, cardiovascular, or other medical conditions that may interfere with stable diet or physical activity during the study. * Pregnant or breastfeeding women. * Inability or unwillingness to comply with continuous glucose monitoring (CGM) procedures for 14 days. * Participants with skin conditions or allergies that prevent safe use of a CGM sensor. * Current participation in another clinical trial that could affect study results. * Use of medications that significantly alter glucose metabolism or interfere with CGM accuracy. * Inability to attend all scheduled study visits or complete required records (diet logs, photos, questionnaires). * Any condition judged by the investigators to make the participant unsuitable for the study or unable to provide informed consent.
