The relationship between the keto diet and blood sugar is one of the most studied areas in nutrition science. Reducing carbohydrates dramatically can have a profound impact on glucose regulation.
Every carbohydrate you eat is broken down into glucose. This glucose enters the bloodstream and triggers insulin release. The more carbs you eat, the larger the blood sugar spike.
By restricting carbs to 20–50g per day, the keto diet dramatically reduces the glucose load on your body. Blood sugar levels stabilise, insulin requirements drop and many people see significant improvements in their HbA1c readings.
Multiple clinical trials have shown that low-carbohydrate diets can reduce HbA1c by 1–2 percentage points in people with Type 2 diabetes — comparable to or better than some medications.
If you take insulin or diabetes medication, reducing carbs can cause blood sugar to drop too low. Always monitor closely and work with your healthcare team to adjust your medication.
