Seven Common Mistakes When Following a Low-Carb Diet for Diabetes

A low-carb diet can be an effective tool for managing type 2 diabetes. However, navigating it successfully requires awareness to avoid these common pitfalls.

1. Not Tailoring Your Carb Intake

There is no one-size-fits-all recommendation for the number of carbs on a low-carb diet. Patti Urbanski, RD, CDCES—a clinical dietitian and diabetes educator—notes that most Americans get about 45% of their daily calories from carbohydrates. For this reason, eating fewer than 26% of your calories from carbs qualifies as a low-carbohydrate approach.

Consider someone with a 2,000-calorie intake: consuming less than 130 grams (g) of carbohydrates per day would fall into the low-carb category. However, very-low-carb diets—including the ketogenic diet—typically restrict total carbs to as little as 20–50 g daily.

When determining your carb target, consider individual factors like blood sugar control, medications, other health conditions, food preferences, budget, and personal goals. Lori Zanini, RD, CDCES—a registered dietitian in private practice—emphasizes that finding the right balance is highly personalized.

2. Not Consulting Your Healthcare Team

Your diabetes care team can provide crucial guidance on adjusting your carb intake safely based on your specific needs and medications.

If you’re prescribed insulin, insulin-stimulating drugs, blood pressure meds, or SGLT2 inhibitors (like Invokana, Farxiga, Jardiance), it’s especially important to consult them before making significant dietary changes. These medications can be affected by low-carb eating habits; for instance, those using SGLT2 inhibitors should avoid drastically cutting carbs without medical supervision.

Furthermore, your healthcare provider may need to adjust your medication dosages if you’re significantly reducing carb intake. Regular check-ins help manage potential side effects like hypoglycemia or electrolyte imbalances.

3. Not Monitoring Blood Sugar Levels

A continuous glucose monitor (CGM) offers real-time data every five minutes, helping individuals adjust portion sizes and medication effectively.

4. Focusing Solely on Carb Quantity Without Considering Quality

Zanini advises that a low-carb diet shouldn’t just be about limiting carbs but also prioritizing high-quality carbohydrates—whole grains, fruits, vegetables—in place of refined ones like white bread or sugary snacks.

5. Consuming Carbs in One Big Meal Instead of Spreading Them Out

Distributing carbohydrate intake evenly throughout the day can help maintain stable blood sugar levels and prevent energy crashes.

6. Neglecting Fiber Intake

Fiber is a crucial nutrient for diabetes management, aiding with satiety, blood sugar stability, and overall digestive health.

7. Inadequate Hydration Risks Dehydration

Low-carb diets can increase the risk of dehydration due to shifts in electrolyte balance as carb stores deplete.
