Food-i-Sense Analytics: Using AI to Understand How Your Glucose Changes Day to Day

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Researchers will collect CGM data from adults aged 18-70 over 14 days and apply the GLIA algorithm to identify glucotypes, then explore how these patterns relate to health indicators like blood pressure and cholesterol. The study combines CGM data, AI analysis, and detailed diet and lifestyle records to generate individualized glucose-phenotype profiles. No treatment is given; instead, the aim is to improve understanding of glycemic dynamics to support precision nutrition. Participants will wear a CGM device, log meals and activity, and complete dietary records during the monitoring period.

* 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.

* 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).
