Walking with Insulin On Board: What You Need to Know
What happens if you go for a walk with rapid-acting insulin still active? Today we’re talking strategy, so you can stay safe, avoid hypos, and still get the benefits. Today, We’re Covering: What “insulin on board” actually means When to...
The episode, word for word
I'm Neil Greathouse, T1D since 1992, coach, podcast guy, and someone who once tried to log their steps using a flip phone pedometer.
Welcome to Your Best T1D Year, the podcast where we take one habit each month and make life with type 1 diabetes feel like something you can actually win at.
You deserve a version of T1D that feels doable, not all-consuming. Let's take one small step in that direction. I'll keep this short. Because long podcasts give me trust issues, and also, I get distracted easily.
Alright, time for one of the coolest facts about walking and blood sugar:
There's actually a study that calculated this: About 3,400 extra steps in the 12 hours before a meal was equal to one unit of rapid-acting insulin in terms of glucose-lowering effect.
That's wild. That means your muscles can do the same job as insulin, just by getting you moving.
Now, don't go canceling your insulin... this isn't that kind of podcast. But it shows us that walking is not just a "nice-to-have" habit, it changes how our body uses insulin.
Even small increases in steps have real results. Going from 5,000 to 7,000 steps daily? That shift alone was associated with better insulin sensitivity, fewer post-meal spikes, and less insulin needed.
And let's be honest, we've all had those days where we're sitting at 220, waiting for a correction dose to do something... and instead of sitting there like George Costanza saying,
"These pretzels are making me thirsty," maybe we throw on some shoes and do a few laps.
Movement gets blood flowing, insulin circulating, and your body responding.
So today, try stacking a short walk with your insulin. Before or after a meal, doesn't matter. Just try it.
