The Glucose Field Guide
A daily field guide to blood sugar

Your breakfast is doing something. I wear the monitor that shows what.

Every weekday I eat one ordinary food with a glucose monitor on my arm, then show you the chart. Smoothies, oatmeal, pizza, wine. No food is off limits, and nothing gets a free pass.

The same dinner, eaten two ways. Illustrative glucose response.
How this started

A phone call from my doctor, and a very ordinary plate of pasta

A routine blood test showed my blood sugar drifting the wrong way. Not diabetes, but heading in that direction. With my family history, that got my attention.

So I stuck a glucose monitor on the back of my arm and started with my weeknight dinner: pasta, garlic bread, a side salad.

First I ate it the way most people do, bread and pasta first. Then I ate the same dinner again, salad first, carbs last, with ten slow squats in the kitchen afterwards. My kids thought I had lost it.

Same plate. Same food. A completely different line on the monitor.

Carbs first, then sit
+72
points
58%
smaller rise
Salad first, then squats
+30
points

A 2015 study in Diabetes Care found that eating vegetables and protein before carbs lowered post meal glucose by around 35%. A 2025 study from Zhejiang University found ten squats after eating cut the rise by a further 21%.
