Your conclusion presupposes we buy into the "keto diet is healthy" proposition.
However, there is a preponderance of real data that fats have been demonized by the sugar industry in the past, and HGI foods (high-carb, generally) are a bigger issue.
Yeah, this reads like popular health guidance left over from the 1980's. Back then we though that "fat makes you fat" and shifted to sweeteners to make food taste good. Later, we found out that was all due to the sugar industry.
Indeed, lots of anti-fat researched was sponsored by sugary drink companies.
But the jury is still against too much saturated fat, since the lymphatic system doesn't handle it in the healthiest of ways. So limiting saturated fats is still the WHO recommendation.
I was responding to the other poster saying that the rules were entirely opened up by the exceptions. Other than meat, it's a freak ingredient like avocado or maybe some nuts that has that much fat.
Excess sugar and simple starches tend to get absorbed more completely than excess fat, I'm not sure added fat is the biggest issue.
