My Metabolic Twin — Your Personalised Glucose AI

My Metabolic Twin is your personal glucose forecaster inside JourneyForHealth — an AI that learns your body and helps you plan meals and days that keep you in range. This page walks through what you see, how the twin learns, and how to use it day to day. It is an educational decision-support aid, not a diagnosis or a medical device.

What you see

Open My Twin and you land on a simple dashboard built around you. At the top is your current glucose state and today's predicted pattern. Below it, a meal preview lets you enter or pick a meal and instantly see the glucose response the twin expects for you — a rough curve showing how high you are likely to go and how long it takes to settle. Alongside are your personal highlights: the foods that tend to spike you, the ones your body handles well, and the timing and habits that help.

How it learns

Your twin gets smarter the more you feed it. It combines your glucose data (from a connected CGM or your manual entries), the meals you log, your movement, and your sleep. Each time a real reading comes in after a meal, the twin compares it to what it predicted and adjusts — so the forecasts become tuned to you rather than to population averages. This mirrors well-established personalised-nutrition science showing that individual glucose responses are highly variable and best predicted from a person's own data.

You do not need to do anything special for it to learn — logging meals and keeping your glucose data flowing is enough. The more consistent your logging in the first couple of weeks, the faster your twin becomes accurate.

How to use it day to day

1. Preview before you eat. Check a meal in the twin, and if the predicted spike looks high, try a swap, a smaller portion, or eating protein and fibre first.
2. Plan your timing. See how the same meal behaves at breakfast versus dinner and choose the better slot.
3. Test movement. Add a short post-meal walk in the preview and watch the predicted curve flatten, then do it for real.
4. Review your patterns weekly. Use the highlights to build a shortlist of go-to meals your body tolerates well.
5. Bring it to your care team. Share what you are learning so any clinician-supervised changes are grounded in your data.

Your personal insights

Over time the twin surfaces the handful of things that matter most for you: your top spike triggers, your best-tolerated staples, and the daily habits — sleep, movement, meal timing — that keep you steady. These insights update as your body and routine change, so the guidance stays current rather than static.

Privacy and control

Your twin is built from your own data, and you stay in control of it. You can review what you have logged, correct entries, and share reports with your care team when you choose. The twin is there to inform your decisions, not to make them for you.

What it is not

My Metabolic Twin is a screening and decision-support aid, not a diagnosis and not an FDA-cleared medical device. Predictions are estimates that improve with data but are not guarantees. This is a screening aid, not a diagnosis — confirm findings with a clinician. Never change medication, including insulin or GLP-1 medicines, without your clinician's supervision.

Frequently Asked Questions

How long before my twin is accurate?

Most people see useful, personalised forecasts within a week or two of consistent logging, and accuracy keeps improving after that.

Do I need a CGM?

A CGM gives the best results, but the twin also works with regular manual readings. The key is steady data.

Can the twin tell me to change my medication?

No. It offers insights to discuss with your clinician; medication decisions are always clinician-led.
