How This Works

The estimator applies research-based glucose reduction rates per minute of walking, scaled by pace and timing. Base rates:

Slow: 0.5 * Moderate: 0.8 * Brisk: 1.2 mg/dL per minute of walking

Post-meal timing applies a x1.5 multiplier - research consistently shows that a 10-15 minute walk after eating is more effective at blunting glucose spikes than a longer walk at other times. This is because muscle contractions during the post-meal window can help transport glucose out of the bloodstream independently of insulin.

BG reduction = base_rate x timing_multiplier x duration_factor

A diminishing returns factor applies after 45 minutes - the marginal glucose-lowering effect per additional minute decreases as glycogen stores in muscles become partially replenished during the walk. The chart shows how your blood glucose is estimated to decline through your session.

Individual responses vary. If your blood glucose is below 100 mg/dL (5.6 mmol/L), take a small snack before walking to avoid hypoglycaemia.

Do not walk if your blood glucose is below 100 mg/dL (5.6 mmol/L) without first eating carbohydrates. Individual results may vary.
