Wellness in a Chaotic World
Wellness in a Chaotic World explores what it means to take ownership of your own health and wellness in a world that doesn't support a healthy lifestyle. If you feel drained by the expectations of modern life or you know what it’s like to be in a downward spiral of negative self-talk when you make a less-than-healthy decision for yourself, you’re in the right place. Join your host, Sheryl Davis, for conversations with real people learning to live well in our unhealthy, stressed-out, and chaotic world.

Ep. 33 - Walking to Prevent Type 2 Diabetes: Does it Make a Difference?
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
If you’ve been told you have prediabetes, chances are you’ve heard that you should exercise more.
But what does that actually mean? Does movement have to be a full workout to make a difference? And can something as simple as a 10-minute walk after a meal really affect your blood sugar?
In this episode of Wellness in a Chaotic World, we’re looking at what the research says about walking, post-meal blood sugar, and shorter bouts of movement.
We’ll talk about why working muscles can take up more glucose, including the fascinating role of GLUT4 glucose transporters, what studies have found about walking after meals and breaking up prolonged sitting, and why you don’t necessarily need to think of movement as a 30-minute workout for it to count.
Most importantly, we’ll bring the research back to real life. Instead of looking for the perfect walking routine, you’ll be invited to consider where a little more movement might realistically fit into your own day and what you might want to experiment with.
In this episode:
- Why physical activity matters for blood sugar
- How muscle contraction helps your muscles take up glucose
- What research tells us about 10- and 15-minute walks after meals
- Why even shorter movement breaks may matter
- How to experiment with walking without turning it into another all-or-nothing health goal
