The standard Glycemic Index treats everyone the same. But your body isn't average — and your glucose management shouldn't be either. GluSteady™'s Personal Glycemic Index™ learns how your unique body responds to every food you eat.
Get Early AccessThe Glycemic Index was a breakthrough when it was introduced. It gave people a simple number to understand how foods affect blood sugar. But there's a fundamental flaw: it's based on averages from tiny test groups — and your body isn't average.
A banana has a GI of ~51 according to standard charts. But research shows your actual response could range from 25 to 125 depending on your biology. That single number? It might be dangerously wrong for you.
Based on: Averages from 5–10 test subjects, tested once, in a lab. Ignores your genetics, microbiome, sleep, stress, and activity.
Your Personal Glycemic Index™ is calculated from your real glucose data, your food logs, and your patterns. It adapts as your body changes — because your glycemic response today might differ from last month.
Based on: Your continuous glucose data, your meal history, your activity, your sleep — analyzed by AI that learns your unique physiology.
The concept of a personalized glycemic response isn't new. Researchers have long known that individual responses to the same food vary dramatically. A landmark peer-reviewed study in IUBMB Life demonstrated up to five-fold differences in glycemic response between individuals eating identical foods — and introduced the term "personal glycemic indexes" to describe this phenomenon.
In 2015, researchers at the Weizmann Institute of Science published a groundbreaking study in Cell showing that personalized dietary recommendations based on individual glucose monitoring were significantly more effective than standard dietary guidelines. The science is clear: your glycemic response is as unique as your fingerprint.
GluSteady™'s Personal Glycemic Index™ technology builds on this research. Our patent-pending AI analyzes your continuous glucose monitor data alongside your food logs, activity, sleep, and other contextual factors to calculate a personalized glycemic score for every food you eat. Not a population average. Your number.
Research consistently shows that population-averaged glycemic index values can be misleading for individuals.
GluSteady™ doesn't guess. It learns from your real data to build a glycemic profile that's uniquely yours.
Link your continuous glucose monitor (CGM) or manually log your blood sugar readings. GluSteady™ works with all major CGM platforms including Dexcom, Libre, and Medtronic. The more data, the smarter your Personal Glycemic Index™ becomes.
Use our AI-powered food scanner or search our comprehensive database. GluSteady™ tracks not just what you eat, but when you eat, what you ate before, and the context surrounding each meal — all factors that influence your personal glycemic response.
Our patent-pending AI engine correlates your glucose responses with your food intake, activity, sleep, and time-of-day patterns. Within days, GluSteady™ begins calculating your Personal Glycemic Index™ for the foods you eat most often.
Once your Personal Glycemic Index™ profile is established, GluSteady™ can predict how new foods will affect you — before you eat them. See a projected glucose curve, get smarter substitution suggestions, and build meals optimized for your body.
Whether you're managing diabetes, preventing it, or optimizing your metabolic health — knowing your Personal Glycemic Index™ changes the game.
Stop relying on generic GI charts. Know exactly which foods spike your blood sugar and which ones keep you steady. Your Personal Glycemic Index™ is based on your real data, not someone else's.
GluSteady™'s AI uses your Personal Glycemic Index™ to show you a projected glucose curve before you eat. Make informed choices, swap ingredients, and avoid surprises.
Your Personal Glycemic Index™ isn't static. As your health improves, your responses change. Track how your PGI scores shift over weeks and months — tangible proof that your efforts are working.
Your gut microbiome, genetics, insulin sensitivity, sleep patterns, and stress levels all influence your glycemic response. Your Personal Glycemic Index™ accounts for all of it.
Type 1 Diabetes: Make more accurate insulin dosing decisions with a Personal Glycemic Index™ that reflects how your body actually responds to specific foods — not how a test group did decades ago.
Type 2 Diabetes: Discover which foods genuinely work for your body. Many people with Type 2 diabetes follow standard low-GI diets and still experience unexpected spikes. Your Personal Glycemic Index™ eliminates the mystery.
Prediabetes & Prevention: Catch problems before they escalate. Your Personal Glycemic Index™ can reveal hidden sensitivities to foods that standard charts rate as "safe" — giving you the insight to change course early.
Gestational Diabetes: Pregnancy changes everything, including your glycemic responses. A Personal Glycemic Index™ built from your current data helps you manage blood sugar through each trimester.
Metabolic Health Optimization: Even without diabetes, understanding your Personal Glycemic Index™ helps optimize energy, focus, weight management, and long-term metabolic health. Know your body. Eat smarter.
A Personal Glycemic Index (PGI) measures how your specific body responds to individual foods. Unlike the standard Glycemic Index — which averages responses across a small group of test subjects — your Personal Glycemic Index™ is calculated from your own glucose data, reflecting your unique biology, gut microbiome, insulin sensitivity, and metabolic patterns. GluSteady™'s patent-pending Personal Glycemic Index™ technology uses AI to build and refine your PGI automatically from your CGM and food log data.
The standard Glycemic Index assigns a single number to each food based on average responses from a small test group. Your Personal Glycemic Index™ is different — it's calculated from YOUR actual glucose data and reflects YOUR unique response. Research shows that two people can have wildly different glycemic responses to the exact same food, making generic GI charts unreliable for individual decision-making.
GluSteady™'s patent-pending AI engine analyzes your continuous glucose monitor data alongside your food logs, activity data, sleep patterns, and time-of-day information. It correlates your glucose responses with specific foods and contexts to build a comprehensive Personal Glycemic Index™ profile. The more data you provide, the more accurate and predictive your PGI becomes.
While a continuous glucose monitor provides the most accurate and detailed data for building your Personal Glycemic Index™, GluSteady™ also works with manual blood glucose readings. CGM data captures your complete glucose curve after eating, while finger-stick readings provide point-in-time snapshots. Both contribute to your PGI profile.
Peer-reviewed research has identified several factors that cause individual glycemic responses to vary dramatically: gut microbiome composition, genetics, insulin sensitivity, sleep quality, stress levels, physical activity, time of day, and even what you ate at your previous meal. This is why a Personal Glycemic Index™ — based on your own data — is so much more valuable than a generic GI number.
Absolutely. The scientific foundation for personalized glycemic responses is well-established. Key research includes the 2010 Whelan study in IUBMB Life that demonstrated personal glycemic indexes vary up to five-fold between individuals, and the landmark 2015 Weizmann Institute study in Cell involving 800+ participants that proved personalized nutrition based on individual glucose data significantly outperforms standard dietary guidelines.
GluSteady™ begins building your Personal Glycemic Index™ from day one. Within the first week of consistent logging, you'll see PGI scores for your most frequently eaten foods. By week four, your profile is robust enough for predictive capabilities — meaning GluSteady™ can estimate your glycemic response to foods you haven't tried yet.
