Adherence
Interrupting prolonged sitting with frequent, low-volume activity breaks (3 minutes of low-to-moderate activity every 30 minutes) significantly lowers fasting glucose and daily glycemic variability in adults with obesity, but does not improve overall glucose tolerance.
If you have obesity and sit for long periods, try breaking your sitting every 30 minutes with just 3 minutes of light activity (like walking or squats). This simple habit can lower your fasting blood sugar and reduce glucose spikes throughout the day. However, do not expect this alone to fix your overall glucose tolerance; you likely need more volume or intensity of activity for broader metabolic improvements.
Under free-living conditions, FABS lowered fasting glucose and glucose variability. Larger volumes of activity breaks from sitting may be required to promote greater health benefits.
Why this rating
Randomized controlled trial with objective continuous glucose monitoring in a specific population (obesity), though sample size is small (n=16).
