Keto excludes high-carb foods like bread which almost never contribute to a person’s essential vitamin, mineral, and protein intake. Vegan, on the other hand, excludes plenty of foods that are common sources of essential nutrients and especially protein.
It’s obviously possible to be malnourished on any diet, but if you take a normal healthy diet and exclude keto-unfriendly items, it will almost certainly still be a healthy diet. If you did the same for vegan-unfriendly items, on the other hand, you’d almost certainly have an unhealthy diet without consciously finding suitable vegan replacements.
Accurate except for the “instead” part. Road maintenance comes from local taxes, whereas military aid comes from federal taxes.
