Why Exercise Matters for Blood Sugar
Exercise is arguably the most potent non-pharmacological intervention for blood sugar control. A single bout of moderate exercise can reduce blood glucose by 20–40% through insulin-independent glucose uptake by contracting muscles.
Walking: The Underrated Powerhouse
Post-meal walking is one of the simplest and most effective strategies. Just 2–5 minutes of light walking after eating significantly blunts postprandial glucose spikes.
HIIT: Maximum Efficiency
High-intensity interval training can improve insulin sensitivity by up to 58% in as little as two weeks. Canadian research from McMaster University has been instrumental in demonstrating these benefits.
Putting It Together
The optimal exercise prescription combines aerobic activity (150+ minutes/week), resistance training (2+ sessions/week), and reduced sedentary time. The best exercise is the one you'll actually do consistently.
