I only eat animal sourced foods: meat, eggs, milk, drink water & use salt.
Breakfast these days is 6-8 oz of ground beef fried in bacon grease and/or butter with 4-5 strips worth of bacon.
Lunch will be the same except I will use a different brand of bacon for a taste variance.
Dinner is always 3 fried or scrambled eggs with 6-oz of some fried or broiled meat. Mostly beef but we do have pork chops on Sundays & we usually eat a good ribeye or new york strip once a week & the rest of the week is steaks cut from a larger chunk of london broil.
Most evenings after 8pm I will fry up 4-5 slices of bacon.
I only eat when I am hungry. I only eat what my body wants & that makes me feel good. I eat as much as I want at every meal. The numbers will vary from day to day depending on how hungry I am.
If I feel sluggish through the day (almost never happens) I will eat some pemmican & that always gives me the boost I need to make it to the next meal.
