I actually think that would be CLA and not the bad industrial trans fats, although the cheese and junk beef aren't particularly healthy in their own right.
You raise a good point about the Atkins fallacy. If you're insulin resistance and fat cutting out the carbs is a really good move, but it isn't the grand panacea, only a holistic approach is. So they stop eating carbs and they start losing weight, that's great but as the mantra goes, "you don't lose weight to get healthy, you get healthy to lose weight" and these people don't do healthy things. In fact a lot of the time they end up consuming tons of omega 6 and destroying their ratios, becoming deficient in certain nutrients because they don't make use of the entire animal or put any real thought to the types of food they eat, and like you mentioned they even load up on the trans fats sometimes.
That's why I like Mark. He has a superior health philosophy and isn't some monomaniacal, one-track-minded charlatan. He knows his stuff and he can back it all up.
That and he's man-pretty
