Anons, concerning the American diet being a nat sec threat.
I eat 0.5 kg or 1.1 pounds of ground beef per day, with enough water.
If you eat as much as you need, you keep a perfect weigh, and you don't need to shit, because you absorb everything you ate (unless it was spoiled, improperly prepared or too much).
Fat and protein with enough water is what you need for optimal health, eat a fresh fish occasionally as well.
