If adults with type 2 diabetes lose 5% or more of their weight in 3 months using a low-carb app, they see better blood sugar control than those who lose less weight.

If adults with type 2 diabetes eat fewer carbs—dropping from about a third to less than a fifth of their daily calories for three months—they might see their average blood sugar drop by a full point, and the more they cut carbs, the better their blood sugar control tends to get.

People with type 2 diabetes who used the online low-carb program saw their blood sugar drop by about 0.6% and lost around 6 pounds on average.

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.

If you're overweight and have type 2 diabetes, eating fewer carbs and more protein for 6 weeks can slightly lower your blood sugar better than the usual diabetes diet—even if you lose the same amount of weight—because your blood sugar stays more stable throughout the day.

If you have type 2 diabetes and use a low-carb diet app for 3 months, there's a good chance—about half the people in the claim—that your blood sugar could get as low as someone without diabetes.
