What made you try out carnivore keto diet for diabetic ?
When did you begin, How long have you tried?
Are you consistent in every meal or just 1 meal a week?

Congratulations, your brainwash is successful. Enjoy your keto meals. Remember to keep your health insurance in good terms.

Since you are genuinely curious, and responded courteously.

Obviously most who follow keto will argue their way of life.
Just as a religious person would argue their god is the best.
There is always the other side of the argument. Go listen to it.

Ask experience heart surgeons if they do keto meals.
Carnivorous diets are not new, they have been around.
Name change, a few ingredients change, essentialy the same.

Atkin was one the former version names.
Dr Atkin died suddenly and mysteriously.
Then paleo now keto because it cause ketosis.

People find it to be effective at first but over time....
... how many heart specialists would keto or paleo long term.

I learn no matter how right is the facts, people often choose what they feel is nice or convenient. The psychological term is cognitive disonance. Besides who am I to say how others should live their life. If they want heart attack or cancer or diabetes, it is their choice. Enjoy yourself and have a nice day.
