The Claim
Light-intensity walking (3.2 km/h) and moderate-intensity walking (5.8–6.4 km/h) for 2 minutes every 20 minutes during prolonged sitting produce statistically similar reductions in postprandial glucose and insulin responses in overweight adults aged 45–65.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In overweight adults aged 45–65, taking two-minute walks at either a slow or moderate pace every 20 minutes during long periods of sitting results in equal reductions in blood glucose and insulin levels after eating.
See the scientific wording
Light-intensity walking (3.2 km/h) and moderate-intensity walking (5.8–6.4 km/h) for 2 minutes every 20 minutes during prolonged sitting produce statistically similar reductions in postprandial glucose and insulin responses in overweight adults aged 45–65, indicating that even low-effort activity may be sufficient for acute metabolic benefit.
When a person walks even slowly for short periods, their leg muscles contract. This contraction triggers signals inside the muscle cells that move glucose transporters to the cell surface, allowing glucose to enter the muscle from the blood without needing insulin. As a result, blood sugar drops, and the pancreas doesn't need to release as much insulin.

1 studyStudy: Breaking Up Prolonged Sitting Reduces Postprandial Glucose and Insulin Responses
Even a slow walk for just 2 minutes every 20 minutes while sitting can lower blood sugar and insulin after a meal as much as a brisk walk — so you don’t need to exercise hard to get these health benefits.
