Walk after meals
Ten to fifteen minutes after the largest meal of the day. Muscle takes up sugar without insulin being needed for it.
Order of magnitude
Ten to fifteen minutes of walking, started within half an hour of the meal.
Buffey 2022: seven acute one-day trials. Walking breaks cut postprandial glucose (d −0.72) and insulin (d −0.83) versus sitting. A chronic HOMA-IR or fasting-glucose size is missing (G-D7).
Effects in detail
Each row is a directed edge from our database, with range, latency, evidence grade and the condition under which it applies at all.
| Marker | Effect | Latency | Mode of action | Outcome | Evidence | Condition | Sources |
|---|---|---|---|---|---|---|---|
| Fasting glucose | helps. Lowers 8–18 % Buffey 2022 Cohen’s d −0.72 versus sitting, on the post-meal glucose peak, not next-morning fasting glucose. Derived, not a mg/dL pool. | 0–1 weeks | postprandial | no | Evidence grade B | applies regardless of the starting value | |
| Fasting insulin | helps. Lowers 10–25 % Buffey 2022 d −0.83 for postprandial insulin versus sitting, four acute trials. No fasting-insulin row. | 0–1 weeks | postprandial | no | Evidence grade B | applies regardless of the starting value |
What this measure costs
Counteracting effects of the same measure.
No counteracting effect is on file for this measure. That does not mean there is none, only that we found no defensible edge.
Moves without implying progress
Informational or no established effect: the marker moves or was checked, and that is not progress.
| Marker | Effect | Latency | Mode of action | Outcome | Evidence | Condition | Sources |
|---|---|---|---|---|---|---|---|
| Systolic blood pressure | checked, nothing happens. No established effect The seven acute crossover trials of interrupting sitting found no effect on systolic blood pressure from either standing breaks or light walking. Acute evidence only, and null even acutely. | not specified | postprandial | unclear | Evidence grade C | applies regardless of the starting value | |
| HbA1c | checked, nothing happens. No established effect The pooled evidence for interrupting sitting is seven acute one-day crossover trials showing lower postprandial glucose and insulin; no trial has followed the habit long enough to measure HbA1c. A no-effect row by absence of evidence rather than by demonstrated null. | not specified | postprandial | unclear | Evidence grade C | applies regardless of the starting value | |
| HOMA-IR | checked, nothing happens. No established effect Seven acute crossover trials: light-intensity walking breaks lowered postprandial glucose (Cohen's d -0.72, 95 % CI -1.03 to -0.41) and insulin (d -0.83, -1.18 to -0.48). acts_on is postprandial and the chronic row is deliberately none: the meta-analysis authors state that longitudinal free-living studies do not yet exist (gaps.md G-D7). | not specified | postprandial | unclear | Evidence grade C | applies regardless of the starting value |
