Moderate-to-low-intensity exercise snacks, including walking; subgroup analyses examined frequency, sedentary-behavior interruptions, and bout duration.

Exercise Snacks and Glucose: Systematic Review
This systematic review and meta-analysis examined moderate-to-low-intensity exercise snacks in sedentary adults. Across 15 studies, they improved several glucose and lipid measures, but not fasting insulin or HDL cholesterol.

Intervention
Main findings
Across 15 randomized controlled trials, moderate-to-low-intensity exercise snacks significantly improved fasting plasma glucose, total cholesterol, triglycerides, and LDL cholesterol. Effects on fasting insulin and HDL cholesterol were not statistically significant. Walking, more than five daily bouts, and shorter interventions were associated with greater improvements in selected outcomes.
What this may mean in practice
Snacksmate's reading of the evidence — not a quotation from the original paper.
This review suggests that moderate-to-low-intensity exercise snacks can improve several glucose and lipid measures in sedentary adults, although benefits were not seen consistently across all outcomes and the most effective protocol remains uncertain.
