What the progress view measures

What's measured

• Check-in days — how many of the last seven days had at least one check.
• Follow-through — when a check suggested a short after-meal action, how often you marked it done.

These appear in your weekly recap as plain sentences — no composite score, no bands, no percentages. Checking less as you get more confident is how Prediabetes Pal is meant to work, so the recap states facts that cannot "decline." The recap is refreshed once a week, early Monday, from the seven days before. (Prediabetes Pal also computes an internal behavioral index to measure the product itself; it is never shown to you and never predicts anything about your health.)

The research this is grounded in

Prediabetes Pal doesn't invent behavior science — it points at published research and asks you to build the habit yourself. None of the following describes Prediabetes Pal's own users or promises what will happen to your own numbers; each is a citation for why checking in and following through are the behaviors worth building.

• CDC DPP — a large randomized trial (NEJM, 2002) found a 58% reduction in progression to type 2 diabetes among participants who made sustained diet and activity changes, compared with placebo.
• Jenkins et al., 2008 (American Journal of Clinical Nutrition) — a dietary intervention study associated with meaningful average A1C change over 24 weeks among its participants.
• Imai et al., 2023(Nutrients) — vegetable- or protein-first meal sequencing was associated with a 29% reduction in post-meal glucose spikes among study participants, the basis for Prediabetes Pal's sequencing tip.

An honest limit

Individual results vary, and Prediabetes Pal has no way to know yours. The weekly recap tracks behavior you can see and control — checking in, and following through. Only a blood test ordered by a clinician measures your actual A1C. Please talk with your clinician about your own numbers and any changes to your care.
