You crave salt and fat because your body needs a little bit of these things to survive, but finding salt and fat out in nature is really really hard, so those cavemen that liked the taste of salty or fatty foods enough to make the extra effort to find those foods were more likely to survive to be your ancestors and you inherited that behaviour. That’s why you like McDonald’s, it’s full of the salt and fat that is hard to obtain if your diet consists of mostly roots and mushrooms and leaves.
McDonalds is bad for you because it’s unnaturally full of salt and fat. Far, far more than your body needs and far more than your cavemen ancestors would have eaten naturally. Especially if you eat McDonald’s often. Too much of anything turns that thing into a poison.
McDonald’s has only been around a generation or two. That’s not enough time for the people who crave McDonalds and eat too much of it to die off, leaving mostly people who don’t crave McDonalds to remain.
Don’t forget the big one, carbs. Carbohydrates are fairly hard to find in nature, even if you have a carnivorous diet and you get plenty of fat and proteins, you will desperately crave carbohydrates which are easier for the body to convert to energy than just fat by itself, and most animals were pretty lean so you would be very lucky to even get a lot of fat in your diet to begin with. If you just eat lean meat you will die.
Fruit, starchy tubers, honey and other natural sugars were prized sources of energy, this is why we love sweets so much and why a package of oily french fries feels like heaven, you are responding to natural imperatives that still think you’re at risk of starving.
