Ironic, given that a higher-fat diet results in the consumption of more grain overall, used in fattening-up the cattle to be eaten.
The Food Pyramid results in the consumption of less grain overall.
That’s because a lot of people eat their red meat with a bun, french fries, ketchup, dessert, and a coke, eating 200+g of carbs in a single meal (vs the 40-50g of carbs max in a day, net of fiber).
I buy grass fed beef. It's more expensive but I only eat about 6 ounces at a time.
