What I eat, and I will admit I have strayed from this eating regiment due to some very challenging events in my recent life, although I am now on a strict eating schedule, is primarily chuck roast. Sometimes as a roast, sometimes cubed and prepared and sometimes ground with salt and garlic powder. In other words I make my own hamburger. I know what's in it. No snouts or eye balls.
I also prepare chicken in various ways and pork. (very little pork) Some fish.
I can't cut out 100% carbs. I use onions in my meals, they have carbs.
I use vegetables in my meals. Cauliflower, cabbage, asparagus, brussels sprouts. I make my own tomato red sauce.
Some nuts and berries. All of these items have carbohydrates but as I understand it, very few. A little research helps.
I do, however eat one meal a day. Primarily meat. I never thought I could do it. I read that your body sustains itself
quite well on the meat and fat from the meat. I realized this first hand and yes, I do get hungry towards the end of 22 or 24 hours, but that hunger is quite manageable.
The important thing is finding out what has large amount of carbohydrates and avoid that product altogether.
Primarily processed food!
When I really want to loose weight from some I have gained, which is actually 6 or 7 pounds, I stay with a strictly carnivore diet. I find it hard to do that after a few weeks and I start adding the red sauce or cabbage or other low carb foods. For a while.
