If the epic, explosive scale of obesity, diabetes and heart disease under the modern government recommended high-carbohydrate, low-fat diet doesn't give you pause, then.... I just don't know what to say.
It makes you wonder what would happen if they recommended the opposite for a generation, what would happen. Would recommending a ketoish diet improve health outcomes? Or does the recommendation mean almost nothing and people will just eat whatever is sold by big food.
Yes, the recommendations appear to mean almost nothing. Americans didn't even reduce the amount of fat consumed since the government started recommending that they eat less fat. They just haven't increased it as much as they increased the amount of carbs consumed. https://www.washingtonpost.com/lifestyle/food/did-the-govern...
