What Is the Keto Diet?
The ketogenic diet, or keto, is a high-fat, moderate-protein, and very low-carb eating plan. The primary goal is to switch the body’s main energy source from glucose to ketones — a process known as ketosis. This metabolic state may help reduce blood sugar levels, which is especially beneficial for those with insulin resistance or type 2 diabetes.
How Keto May Help Diabetics
Research shows that a low-carb, high-fat diet can improve insulin sensitivity and lead to better blood glucose control. A 2022 study published by the National Institutes of Health (NIH) found that people with type 2 diabetes following a keto diet experienced significant reductions in A1C levels and fasting glucose.
Some potential benefits of keto for diabetics include:
- Lower blood sugar and insulin levels
- Improved HbA1c over time
- Reduced dependency on diabetes medications
- Weight loss, which can further aid glucose control

Potential Risks of Keto for Diabetics
While keto has promising benefits, it may not be suitable for everyone — especially people with type 1 diabetes or those prone to diabetic ketoacidosis (DKA). Rapid changes in blood glucose can also affect medications, so it's important to consult your doctor before starting keto.
Common side effects include:
- Keto flu: fatigue, dizziness, nausea
- Digestive changes
- Electrolyte imbalances
Always monitor your blood sugar closely and work with a healthcare provider to adjust medications if needed. For easy and safe snack ideas, check out these keto snacks that won’t kick you out of ketosis.
