alt Hacker NewsWorth noting that ruminants have less variance between "good diets" and "bad diets" for the animals than other animal protein sources. IE: you're better off with a grain fed steak than an unnaturally fed non-ruminant animal.
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.
Yeah, I agree, I'm not really a calorie counter. (I tend to get irritated by the "a calorie is a calorie" folk because nutrient quality is the most important thing). It's occasionally worth paying attention to calories with some foods though, like bacon or whatnot because it's very easy to eat a small volume but a lot of calories.
