The Claim
In prediabetic adults, a single session of high-intensity exercise reduces the late-phase postprandial glucose response to an oral glucose tolerance test by 13% compared to rest, whereas moderate-intensity exercise does not have a statistically significant effect.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
For people with prediabetes, doing one intense workout can lower the big sugar spike that happens after a sugary drink by about 13% compared to not exercising. A moderate workout also seems to help a little, but that change is so small it might just be by chance.
See the scientific wording
In prediabetic adults, a single bout of high-intensity exercise can significantly reduce the late-phase postprandial glucose response to an oral glucose tolerance test by 13% compared to rest, while moderate exercise shows a nonsignificant trend.
When you exercise really hard, your body releases stress hormones that make your liver and muscles release stored sugar into your blood. This makes your blood sugar go up temporarily. After you stop, those hormones wear off, and your body makes a lot of insulin to clear the extra sugar and refill your muscles' energy stores. This process makes your body better at using insulin, so after your next meal, your blood sugar stays lower.
What the research says
1 studyA hard workout clearly helped lower blood sugar after eating, but an easier workout didn't show a clear benefit.
