yes, thus their point. It's probably not the sweetener or sugar in the coffee, it's that folks who add sweetener are also more likely to have a lifestyle that gives them type 2.

Or a separate effect where people whose doctors tell them they’re a diabetes risk tend to make a token switch to artificial sweeteners, but don’t take other, more effective steps.

Hopefully their doctors would also have told them that using artificial sweeteners doesn't help protect against insulin resistance.
