Oftentimes I will have patients with diabetes whose blood sugars are high, and they think, logically, that if they eat very few (or no) carbohydrates, that will help. Unfortunately, they are working against themselves, and here’s why:
The body has what I like to refer to as a savings account of glucose in the liver. When the cells in the body aren’t getting the glucose they need for energy (like when someone skips a meal or when their cells are resistant to insulin), they start complaining all over the body trying to get someone to fix their problem. Word gets to the liver that the cells are starving and he wants to help. The trouble is, liver is a busy guy. He’s got many, many jobs. I often joke that managing this savings account is his “side gig.” He’s not particularly good at it.
In people with diabetes, liver sometimes starts dumping glucose from his savings account into the blood when he doesn’t really need to, and also he doesn’t know when to stop. He just keeps pouring and pouring sugar into the blood and before you know it, this poor person who is trying their darnedest to avoid eating carbs in order to get their blood sugars down has a sky-high blood sugar because they haven’t eaten!
It’s the most frustrating thing in the world because it’s totally backwards to what we would naturally think.
Moral of the story: don’t skip meals, and don’t over-restrict carbohydrates! It’s just as important to eat enough as it is to not eat too much to manage blood sugars in diabetes (side note: that’s true for weight loss as well!).
Bonus sub-moral of the story: If you have something frustrating going on with your blood sugars or your weight that you can’t explain, seek out a Registered Dietitian or a Certified Diabetes Educator to help explain all the funky things that your body might be doing without your realizing it! You don’t have to be frustrated and helpless. You can be empowered to better understand your body!
