The Claim

Interrupting prolonged sitting with 2-minute standing bouts every 20 minutes has no significant effect on postprandial glucose or insulin responses compared to uninterrupted sitting in inactive middle-aged men.

Source: Intermittent walking, but not standing, improves postprandial insulin and glucose relative to sustained sitting: A randomised cross-over study in inactive middle-aged men.

In plain English

In inactive middle-aged men, taking 2-minute standing breaks every 20 minutes during prolonged sitting does not change blood glucose or insulin levels after eating compared to sitting continuously.

See the scientific wording

Interrupting prolonged sitting with 2-minute standing bouts every 20 minutes has no significant effect on postprandial glucose or insulin responses compared to uninterrupted sitting in inactive middle-aged men.

Why this might work

When a person stands but does not move, the leg muscles do not contract enough to trigger the cellular machinery that pulls sugar from the blood. Without muscle contraction, the transporters that move sugar into muscle cells stay inactive, so blood sugar and insulin levels remain high after eating. Walking activates these transporters, but standing alone does not.

    This study found that just standing up for 2 minutes every 20 minutes while sitting doesn't help lower blood sugar or insulin after eating in inactive middle-aged men — it's no better than staying seated the whole time.
