For adults with prediabetes, exercising at a higher intensity (80% of maximum heart rate) lowers blood sugar and insulin after meals just as much or more than exercising at a lower intensity (70%), but it feels harder and is harder to keep up over time.

Exercise intensities and metabolic health: Targeting blood glucose, insulin, and C-peptide levels in adults with prediabetes in the postprandial state

Randomized Controlled Trial

Human

2024 Oct

The study found that exercising at 70% of max heart rate lowered blood sugar and insulin better than higher intensities, and didn't even test whether 80% was harder to keep up with. So it says the opposite of the claim.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

For adults with prediabetes, exercising at 70% of their maximum heart rate lowers blood sugar after a meal by about 50 mg/dL within an hour, more than exercising at lower intensities.

For adults with prediabetes, exercising at 70% of their maximum heart rate helps blood insulin levels return to fasting levels more quickly after eating, which suggests the body is using insulin more efficiently.

For adults with prediabetes, exercising on a treadmill for 30 minutes at 70% of their maximum heart rate after eating leads to a larger drop in blood sugar and insulin levels afterward than exercising at lower or higher intensities.

For adults with prediabetes, exercising at 70% of their maximum heart rate leads to a larger drop in C-peptide levels after eating than exercising at higher or lower intensities, indicating a difference in how the body handles insulin production or demand.

If you eat before working out, your blood sugar and insulin levels spike more during exercise than if you work out on an empty stomach.
