It depends on what you are consuming as calories.
During the week, I tend to eat 1-2 lbs of meat a day. I also eat several pats (maybe a half-stick) of butter. And some milk, but not much. Today I had about 1 lb of sausage, a little less than 1 lb of steak, and 6 oz of of pepperoni. Probably a little heavier day, but Mondays often are, because I eat a lot less most weekends. This weekend, I think I had about 5 eggs and one big piece of salmon, maybe a lb, probably less. That's over 2 days. I also drink a lot of coffee and water. Tomorrow I plan to have about 1 lb of steak, and 12 oz of shrimp.
I don't know how many calories that is. I don't necessarily try to eat one meal a day, but often do on the weekends, or sometimes even skip a day. I do try to eat between 10a and 4p, but sometimes have a snack before bed.
This is plenty to keep me feeling satiated. It is still probably far less than most diets, but I don't have sugar cravings and energy drops every couple hours to worry about and feed, and I'm not stuffing myself with filler foods (starches, pasta, rice) to be "full".
And I have more energy than ever, even throughout the day. Again, thanks to not depending on sugars/carbs for energy.
This isn't a perfect diet, but where I'm at right now. Ideally I would eat less sausage and cured meats. Often curing means dextrose, and possibly corn syrup and/or sugar in sausage. Got to be really careful.
