When it comes to gestational diabetes, it's not just what you eat....
...but also how you eat.
Eating more calories than the body can process either in a single sitting or throughout the day increases risk. And this can happen in women with normal BMI.
Recent studies are shifting how we think about GDM risk. It's not just about carbohydrates. Fats and proteins also contribute when intake is too high. Diets higher in processed foods also increase the risk.
👉 In some studies, higher pre-pregnancy calorie intake doubled the risk of GDM... Regardless of exercise status.
So what's actually happening?
Your body has to process every calorie you eat, regardless of the source. This processing requires insulin signaling, cellular energy production, nutrients to support metabolism, antioxidants to neutralize the byproducts of metabolism, and time to rest and digest and recover.
When intake exceeds capacity, even with healthy foods, your body starts to feel overworked and underpaid. This increases oxidative stress, and overworks Insulin producing cells. This creates strain on the systems involved in gestational diabetes, without the added sugar.
Think of it this way. Your metabolism isn't just a calculator, it's a system with a workload and a capacity. If that system is constantly "on" with no brakes it starts to become inefficient. If you tack on more work than the system can handle, it breaks down.
What is interesting with this is that we find that while exercise is helpful, it doesn't compensate for this increased demand. More on this in the next post
