Ketones are good for you. No, they're bad.
With one exception, I don't think that there's any diabetes disagreement that is more serious than this one about ketones. The exception is whether a low-carbohydrate diet is something that you should follow, particularly if you want to lose weight.
Is a low-carb diet good or bad for you? Actually, some of the reason that we differ on the answer to that diet question is because we can't agree on ketones.
We do know what ketones are. Ketones are acids...
