What does lunch do to you?

Now112mg/dL

Islet is a fifteen-day glucose sensor and a coach in your phone. Wear it on your arm, eat the way you already do, and find out which meals keep you steady and which ones drop you at 3 pm.

Same lunch. Eat it in a different order.

Fibre and protein first slow how fast the rice reaches your blood. Nothing on the plate changes, only the order. Drag the courses and watch your afternoon.

Illustrative member responses on one shared scale (70–200 mg/dL). Large person-to-person differences in response to the same food are well documented (Zeevi et al., Cell, 2015).

Walk ten minutes after dinner. Watch the spike shrink.

Working muscles pull glucose out of your blood without waiting for insulin. A short walk soon after eating is one of the cheapest changes there is, and Islet shows you it working on your own dinner.

Fifteen days, folded into one day you'll recognise.

Each sensor ends with a report. Every day is laid over the others, so the noise falls away and your patterns remain: the steady mornings, the one meal that always runs high.
