I can give you a vague menu.
For breakfast I usually eat eggs and maybe some chicken sausage. Sometimes one of those prepared mini omelettes. On a rare occasion I have low sugar oatmeal. Calories are usually 250.
For dinner I usually eat a meal of chicken, pork, fish, or some type of soup that is high in protein. Calories are usually 250-300.
I normally eat snacks of Greek yogurt , certain protein bars, maybe some pistachios, cottage cheese, or lunch meat. I average 800-900 calories a day but I try to eat more on days I’m in the gym or more active.
It is tough as I miss some vegetables and need to find more balance of working them in but I just cannot eat a lot. I get about 75 grams of protein and less than 50 grams of carbs a day currently.
