Doing calf raises (calf-muscle contractions while seated or standing) after a meal can meaningfully cut the glucose spike that follows — one of the easiest ways to move after eating, doable almost anywhere.

The claim is specific and testable, and it holds up well. A study published in iScience (Hamilton et al. 2022) found that sustained soleus (calf muscle) contractions, done while seated, cut the postprandial glucose spike by 52% and the insulin response by 60% compared to sitting still, an effect achieved by engaging barely 1% of body mass. This fits a broader post-meal-movement literature (short walks, stretching) that blunts the glucose rise, also captured in the corpus's post-meal-walk claim. The advantage of calf raises over walking is that they can be done seated, with no need for space or dedicated time, a genuinely practical point. The limit: the studies are small (a few dozen participants) and measure an acute effect on a single meal, not a demonstrated long-term health benefit, but the mechanism and the measurement are solid.
