Because they’re running counter to big agribusiness and other evil government and corporate types, it piques my interest, but most of these people seem dangerously adjacent to “carnivore diet” weirdos. I’m vegan I’m not gonna use tallow dude. Coconut oil would be fine thanks.
Anyone smarter than me know the real score?
The real score is that it's mostly bullshit. Oil and fats should only be watched due to their caloric value (also you should limit trans fats) unless you have a galbladder issue. Like... buttered movie theater popcorn has a few tablespoons of oil/fat, but each tablespoon has 100-200 calories in it, so you've basically just had an entire meal from that alone.
Processed sugars are significantly worse in the quantities in which they're regularly consumed. Really bad for insulin resistance. Really bad for metabolism overall. Bad for your teeth if you don't rinse your mouth and brush them after. Makes you gain weight faster and fucks with fats in your bloodstream. Fine to have in moderation, though, especially if not on an empty stomach.
