increase beef cattle in the United States to almost triple what it is now, and drop the price of beef (ground and regular).
Beef protein and protein in general is one of the main reasons why people have gotten so fat. Grain and carb based diets do not provide enough nutrition for the body, leading to constant hunger and overeating. The Body literally needs to eat meat. Force the entire US population to have about 35% or more of their daily caloric intake to come from protein would drop everyones weight.
Aside that protein is highly satiating (IE, eating 300 calories of steak fills you up better and faster and keeps your hunger cravings from spiking randomly better than 600+ grams of carbs), studies have shown that people who eat more protein and fats generally also eat less calories overall because of how satiating a high protein diet is.
Every society has known this. The more a society eats carbs the fatter usually and definitely dumber it is. Look at the indians for example. They don't eat beef, eat mostly veggies and carbs and all of them are retarded. High-Protein diets lead to civilization, low protein diets lead to decay.
