Intervention

Exercise snack interventions; specific activity protocols were not described in the abstract.

Main findings

Across nine included studies, exercise snacks were associated with a statistically significant increase in lean mass. Effects on body fat and body mass were not statistically significant, and the review found no convincing evidence that exercise snacks reduce body fat.

What this may mean in practice

Snacksmate's reading of the evidence — not a quotation from the original paper.

Current evidence suggests exercise snacks can increase lean mass in adults, but it is insufficient to determine whether they reduce body fat or change overall body mass.
