Low carb diets also increase metabolic stress (specifically ketosis), which is one of the suspected reasons for the additional calorie burn. Ketosis over short periods is good, but scientists differ on whether it is safe in the long-term. For diabetics (Type I or II), ketosis is not safe, as the body does not have the proper insulin response to maintain safe levels of ketosis.

Are there any studies on ketosis and diabetes? Because one of the primary drivers of insulin resistance in type 2 diabetes is being overweight. So, even if ketosis were bad, if losing weight improved your insulin sensitivity, it might still be worth it. Obviously, this shouldn't apply to type 1 diabetics, though.

I'm sorry, this needs a citation. I'm not trying to be a jerk, it's just that with a subject this controversial you can't simply assert claims like this.
