Same pizza. Same amount. Very different glucose curve. 🍕
I’m running this experiment because in my first pregnancies I struggled with blood sugar and delivered bigger babies (9 lb 10 oz + 9 lb 12 oz). By baby five, I started applying simple blood sugar strategies — and had a smaller, smoother pregnancy outcome.
Now I’m 21 weeks with baby seven, wearing a CGM again because I want data — not guesses.
Blue line: pizza + crazy bread + cheese bread.
📈 ~55–60 mg/dL rise. Higher peak. Longer hang time.
Red line: fiber supplement → then the exact same meal.
📉 ~15–17 mg/dL rise. Flatter curve. Smaller peak.
Pregnancy naturally increases insulin resistance, which makes this even more fascinating. My body is supposed to be more resistant right now — yet the curve changed dramatically just by altering the order.
Will this look the same for you? No.
Your response depends on insulin sensitivity, muscle mass, sleep, stress, and pregnancy status.
But physiology doesn’t care about trends.
Fiber slows gastric emptying, reduces glucose absorption speed, and lowers the insulin demand for the same carbs.
Same food. Different hormonal response.
If you appreciate real-life physiology experiments (especially with pizza), like, save, and share with someone who thinks fiber is just hype. 🍕
