Meat industry. They're pushing "big sugar lied to you" (true), "(saturated) fat good for you!", which is contrary to most evidence we have.
Only because sugar is bad for you does not mean fat is good for you. Evidence is rather on the side of complex carbs, high fiber, moderate protein, moderate unsaturated fat and low saturated fat intake.
Yes, fat is 'good for you'. Without consuming it, you die.
But I would say that in general, 'x is good/bad for you' is a harmful oversimplification. Sugar is also not 'bad for you'. It's not that simple. Glucose is important and sometimes extremely beneficial to consume (in any form).
As for saturated fat: it's complicated. Correlation != causation. For transfats we have a pretty good idea via which causal mechanism problems arise. For saturated fat we only have correlations. Given how hard nutritional research is and especially how hard it is to draw conclusions from it, I would say it's better to refrain from feigning confidence on substances where the jury really is still out.
> Frankly, the number of carbs and fiber you need throughout your life is 0
Sincerely, what are you talking about? It's been well-known a diet high in fiber lowers your risk of cardiovascular and metabolic diseases.
Also, no carb diets are largely bullshit. There's plenty of complex carbs with many nutrients. The problem is while "no carb" might be somewhat effective, it's not sustainable for the vast majority of people. That, to me, makes it very close to worthless.
Sure, but this is worthless information. Many processes of your body will be enhanced by carbohydrates and fiber. Not having fiber in your diet will greatly increase your risk of heart attack, stroke, various GI cancers, and diabetes.
For most of humanity, humans ate 100+ grams of fiber a day and had a diet almost entirely composed of carbohydrates. Access to farmed meats is a very new phenomenon. I think this is the part people are missing - they believe paleolithic humans ate mostly meat. They didn't. They ate mostly carbs. Also, the meats they did have had very little saturated fats because they were game meat, not farm meat.
A burger isn't really the same thing as a wild antelope.
