In adults with type 2 diabetes, switching to a very-low-carbohydrate diet lowers daily carbohydrate consumption from about 220–230 grams to 65–80 grams within three months, even without tracking food intake or calories.

Eating fewer carbs might help people with type 2 diabetes who are overweight lose around 8 pounds and improve how their body uses insulin over several months.

If adults with type 2 diabetes use a low-carb diet app for 3 months, they end up eating fewer calories without trying, mostly because they eat less carbs — and they naturally replace those carbs with more protein and fat.

Eating fewer carbs might help people with type 2 diabetes who are overweight manage their blood sugar better, which could lower their chances of developing serious health problems like nerve damage, eye issues, or heart disease over time.

If an obese person with type 2 diabetes eats only 600–850 calories a day for a few months, about half of them will no longer have diabetes after a year—and about a third will still be diabetes-free two years later, especially if they lost a lot of weight early on and haven’t had diabetes for very long.

If you have type 2 diabetes and eat very few carbs (like less than a slice of bread per meal) while getting ongoing support from a doctor or coach, you might lower your blood sugar so much that you can stop taking diabetes meds—and for many people, that improvement lasts a year or even two.
