Oh, and actually plant-centric diets are a better way to achieve satiety than fat. Fats are so calorie dense that it’s way too easy to overconsume before feeling full. Since diets heavy in whole-plant foods are naturally high in fiber and low in overall calories, it’s easier for a person to eat as much as they want and still keep their weight under control. This is why vegans and vegetarians tend to average the lowest bodyweights among dietary groups.

You’re just spouting half-baked influencer nonsense. Sugar is not a demon, carbohydrates are literally the primary fuel that we run on, and virtually every cell in our body uses them. It’s the improper consumption of carbohydrates outside of their natural, intact, whole-food context; as well as within the context of an overall diet that tends to be high in heavily processed foods, extremely low fiber, low antioxidant and other phytonutrient content, way too high in animal products which come packaged with too much saturated fats, especially cured meats, and in lifestyles with other significant risk factors like sedentary, smoking, and excessive alcohol consumption.

Fat has its place, but its role is mainly an emergency store for periods of starvation. Our bodies use these fuels differently too. For example if you look at textbooks on fitness training, they might talk about the myth of “the fat burning zone.” Think of our body’s energy consumption like a set of dimmer switches. The body does not switch between one or the other like a binary, it’s more that it will use differing ratios of all energy sources based partly on activity level. If you’re doing low impact activity like walking or, even just existing, the body will tend to prefer burning a ratio of calories from fat. If you move to higher impact activities, your body will start burning a much higher ratio of calories from carbohydrates. Although going back to that point about the fat burning zone myth, it must be stressed that it is a myth - you’ll burn a lot more fat with higher impact exercise despite the body using more carbs because the overall volume of calories burned is way higher than with low impact, especially if you do something like HIIT.

There is good reason that even relatively conservative fitness organizations like NASM say right in their textbooks - carbs are equally, if not a more important nutrient than protein.

And yeah, the communication about fats in the 80s and 90s was poor. But that doesn’t mean one macro is magically innocent and the other is evil. In the big picture, experts were recommending Mediterranean style diets all the way back then. Industry did not listen. Sure some products were reduced fat - mostly the unpopular ones. And yes they raised sugar levels. But overall, both refined sugar levels, and fat levels have increased in processed food levels over time - especially saturated fats, and when it was legal, trans fats.

But yeah, palm and coconut oils are awful. They’re being put in too many things, and it won’t surprize me if we’re going to start seeing a dip in vegan health outcomes because of that.
