The Claim

Low- to moderate-intensity physical activity performed immediately after breakfast reduces postprandial interstitial glucose exposure (mean and area under the curve) and glucose variability (coefficient of variation) in healthy adults aged 18–65 with normal BMI, compared to no activity or activity performed before or 30 minutes after the meal.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Walking or light exercise right after eating breakfast lowers blood sugar levels after the meal and makes those levels more stable in healthy adults aged 18–65 with normal body weight, compared to not exercising or exercising at other times around the meal.

See the scientific wording

Low- to moderate-intensity physical activity performed immediately after breakfast significantly reduces postprandial interstitial glucose exposure (mean and area under the curve) and glucose variability (coefficient of variation) in healthy adults aged 18–65 with normal BMI, compared to no activity or activity performed before or 30 minutes after the meal, suggesting that timing of activity relative to meals is a critical factor in acute glycemic control.

Why this might work

When muscles move after eating, they pull glucose out of the fluid around them without needing insulin, which lowers blood sugar levels and keeps them steady.

  1. Study: Immediate post-breakfast physical activity improves interstitial postprandial glycemia: a comparison of different activity-meal timings

    Walking or doing light exercises right after eating breakfast helps lower and stabilize blood sugar levels better than waiting 30 minutes or exercising before eating. The study shows it works even with simple movements like standing or squats.
