In healthy young adults, a 10-minute walk right after eating sugar lowers blood glucose levels over the next two hours just as much as a 30-minute walk started half an hour after eating, even though the shorter walk takes less time and feels easier.
See the scientific wording
A 10-minute walk initiated immediately after glucose ingestion reduces the 2-hour postprandial glucose area under the curve to a similar extent as a 30-minute walk initiated 30 minutes after glucose ingestion in healthy young adults.

No contradicting studies found yet
That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
When you walk right after eating sugar, your leg muscles contract and pull glucose out of your blood without needing insulin. This happens because the movement triggers signals inside muscle cells that move glucose transporters to the cell surface, letting more sugar enter the muscle and lowering blood sugar levels faster.

Mechanism
1 studyWalking right after eating sugar makes your leg muscles pull glucose out of your blood without waiting for insulin. This happens fast enough to stop blood sugar from spiking high, so even a short walk right after eating works as well as a longer walk that starts later.
When you walk right after eating sugar, your leg muscles contract and pull glucose out of your blood without needing insulin. This happens because the movement triggers signals inside muscle cells that move glucose transporters to the cell surface, letting more sugar enter the muscle and lowering blood sugar levels faster.
Skeletal muscle contraction during walking activates AMPK and calcium-dependent signaling pathways
AMPK and calcium signaling stimulate translocation of GLUT4 glucose transporters from intracellular vesicles to the sarcolemma
Increased GLUT4 density on the muscle cell membrane enhances glucose transport from blood into muscle cells
Rapid glucose uptake by skeletal muscle reduces systemic blood glucose concentration and lowers peak and cumulative postprandial glucose exposure
