Understanding Insights

Impact score

Every meal gets an impact score from 0 to 100 that summarises how much it affected your glucose. A lower score means a flatter, more stable response. The score combines peak rise, time to return to baseline, and variability into a single number.

Glucose response metrics

Below the impact score you will find detailed metrics for each meal:

• Peak rise — The highest point your glucose reached above your pre-meal baseline.
• Time to peak — How many minutes after eating your glucose hit its highest point.
• Delta — The difference between your pre-meal glucose and your level two hours after eating.
• AUC (area under the curve) — The total glucose exposure above baseline over the post-meal window.

Time in Range

Time in Range shows the percentage of the day your glucose stayed within your target range. Bettie breaks it down into four bands — low, in range, elevated, and high — so you can see where you spend most of your time.

Similar meal comparison

When you log a meal that resembles something you have eaten before, Bettie shows a side-by-side comparison. This helps you spot how small changes — like a different side or a smaller portion — affect your glucose response.

Confidence levels and confounders

Bettie flags when an insight may be less reliable. Factors like exercise, stress, or overlapping meals can influence your glucose independently of the food you ate. When Bettie detects potential confounders it lowers the confidence level shown alongside the insight and explains why.
