Most of the benefits you mention come from weight loss, and almost any intervention that can cut weight during the first years would report similar improvements.

Plenty of people lose weight, drop blood sugar and drop blood pressure by going keto. And some with a more extreme carnivore diet.

The real comparison here would be to have "2 people like you" 6 years ago and have two interventions. One going vegetarian and another going keto or carnivore, and see where there are now.
