What was studied. Researchers pooled seven randomised crossover trials in adults, mostly overweight. On different days, the same people either sat for long periods, or broke up sitting with short bouts of standing or light walking, for example two to five minutes every 20 to 30 minutes.
What they found. Compared with sitting, both standing and light walking breaks lowered blood sugar after meals, and walking showed the larger effect. The effect on insulin and blood pressure was studied in fewer trials.
What it means. Moving a little, often, may help your body handle the sugar from a meal. This fits the simple advice to avoid sitting for hours without a break.
Limits. Each trial lasted a single day, the groups were small, and most participants were overweight, so the results may not apply to everyone. The review does not show lasting benefit and is not a treatment.
