How to improve blood sugar control with exercise

ZOE Science & Nutrition

Blood sugar is one of the rare nutrition topics where everyone agrees: We should avoid big peaks and dips and aim for a steady curve.

Spikes cause inflammation, accelerate aging, and lead to type 2 diabetes. Crashes make us feel moody and tired, and crave foods we don’t need.

We can control our blood sugar through what and how we eat. But something else affects our blood sugar — physical activity.

Exercise has a profound effect on your blood sugar response. Together with your food choices, being physically active helps you keep your blood sugar level even.

In this episode of ZOE Science & Nutrition, Jonathan speaks with Javier Gonzalez and Sarah Berry to find out how exercise affects our blood sugar response — even when we’re fasting — and how much exercise we need to do to benefit.

• Javier Gonzalez is an associate professor of human physiology at the University of Bath whose research focuses on the interaction between diet and exercise.
• Sarah Berry is one of the world's leading experts on human nutrition. She has personally run over 20 randomized clinical trials looking at how humans respond to different fats.
