I enjoy an occasional steak but if the goal is to improve diet of masses, it’s not the food I’d put at the center.
As to the calories, yes calories count, but the fact that it is calorie dense doesn't necessarily mean you should avoid it so much as be aware if you are mixing sources and having excessive meals. I know a lot of people on carnivore diets for inflammatory and diabetic control and the total calorie intake is less of an issue in those cases. Even with a pound of steak and a dozen eggs a day, weight loss is still happening for overweight diabetics on carnivore diets.
Just meat is very sating and impossible for most people to overeat in practice... at least from my own experience and exposure. The relative mono diet also helps with this.
