iDiet HealthWhat is Shadow Glucose? Photograph a meal, estimate its glucose swing
Snap a photo and understand a meal's likely glucose-response trend first — without wearing a sensor continuously.
Photograph one meal and AI estimates that meal's likely post-meal glucose-response trend, with no continuous sensor needed, as a reference for food choices — it does not measure glucose and does not replace a glucose meter or a physician's diagnosis.
What is Shadow Glucose?
直答Shadow Glucose is iDiet's meal glucose-response estimation feature. You photograph a meal, and based on its contents the system estimates the glucose-response trend it may cause — a reference for choosing and adjusting your food, with no need to wear a sensor continuously.
How do you use Shadow Glucose?
What's in the free trial?
直答Free for 3 days, 12 analysis credits, up to 1 per meal; refer a friend who completes sign-up and starts their trial, and get 1 more day (12 more).
How accurate is Shadow Glucose?
直答Shadow Glucose provides estimates and trend references, not measured values. After you complete 10-day CGM metabolic modeling, the system calibrates to your personal metabolic fingerprint, so estimates fit you more closely. Even then, it does not replace a glucose meter or measured CGM data.
What's the difference between Shadow Glucose and CGM?
| SystemSHADOW · CGM | Shadow GlucoseAI estimate | 10-Day CGM Metabolic ModelingMeasured |
|---|---|---|
| Data type | AI estimate (reference) | Measured continuous-glucose data |
| Wear a sensor? | No — just take a photo | Yes — about 10 days |
| What it's for | A quick everyday meal reference | Building your personal metabolic fingerprint |
| Best for | Long-term, low-effort meal tracking | Getting a precise read on your real responses first |
| How they relate | After modeling, Shadow Glucose fits you more closely | Model once, benefit long-term |
Can Shadow Glucose replace my physician?
直答No. Shadow Glucose is a dietary reference tool; it does not provide medical diagnosis or treatment advice. If you have any health concerns, please consult a physician or dietitian.
