Calculators & Tools
Practical tools for transparent everyday decisions.
All calculators provide guidance, not a diagnosis. Discuss laboratory values with your healthcare team; individual factors can differ.
Nutrition calculator
Build a meal and see calories, carbohydrates, sugars, fibre and more at a glance.
HbA1c calculator
Convert HbA1c into estimated average glucose (eAG) and IFCC units (mmol/mol).
Formula eAG: 28.7 × HbA1c − 46.7 (ADAG study) · IFCC: (HbA1c − 2.15) × 10.929
Glucose converter
Quickly convert glucose units used by international sources and devices.
HOMA-IR
Estimates insulin resistance from fasting glucose and fasting insulin.
Formula: (glucose × insulin) ÷ 405 · both values measured fasting
BMI calculator
BMI alone is limited; adding waist circumference gives more context.
Calorie needs
Basal and daily energy needs using Mifflin–St Jeor, plus a modest deficit.
Macro calculator
Distributes daily calories transparently across protein, moderate fat and the remaining carbohydrates.
Fibre check
Your daily target (14 g per 1,000 kcal) and today’s progress.
For comparison: 1 apple ≈ 2.4 g · 100 g lentils ≈ 8 g · 1 slice of wholegrain bread ≈ 4 g
Food comparison
Enter two products per 100 g and compare their likely glucose impact.
Supplement check
Record what you take and prepare questions about the specific products, timing and possible interactions. This is a limited checklist, not a treatment planner.
This tool is a planning aid and knowledge collection — not advice, a recommendation or treatment. Supplements never replace prescribed medicine. Do not stop or start anything without speaking to your doctor or pharmacist, especially when using diabetes medicine.
Some supplements can interfere with each other. This check shows which items should be separated.
What is known about effects on blood glucose and metabolism? A plain assessment, including where research is limited.
TIR & GMI calculator
Review CGM metrics from an AGP report. The result describes data and does not make treatment decisions.
GMI is an estimate calculated from mean sensor glucose. HbA1c and GMI can differ.
Remission check
Explains the formal minimum criteria in the international consensus definition. It is not a diagnosis or a promise of cure.
Remission requires laboratory and medical confirmation. It is not a cure and ongoing follow-up remains necessary.
Meal response log
Document a measured n=1 response. The tool does not predict a glucose peak.
Weight & waist progress
Compare your starting point with the current value. The trend matters more than a single measurement.
CGM curve comparison
Compare two measured glucose series descriptively. Different durations and sensor conditions limit interpretation.
