Te Role of Continuous Glucose Monitoring in AI- Driven Personalization

How AI Enables Personalized PPGR Management

Machine Learning Models for Glucose Prediction

Modern AI systems employ contained searning algorithms - such as gradient boosting machines, randon forests, and deep neural networks - to prospeat an individual 's glucose response after a meal. These models are trained on historical data including meal composition, pre-meal glucose leveil, sleep duration, stress markers, and recent fyzical activity.

Integration of Multi- Omics and Gut Microbiome Data

AI goes beyond diet and activity logs by incorporating multi-omics data such as genomics, metabolics, and gut microbiome composition.
