I've noticed that when I eat foods high in protein, they seem to "sit" with me longer and it takes longer for me to get hungry again, which is great on a low-calorie diet. I gravitate to protein like grilled chicken, baked fish, and peanuts. I also weightlift about four times a week.
I calorie-count, so I thought about experimenting for a few days and eating about 90% protein, maybe take a multi-vitamin daily. The extra protein will be great for my muscle repair, and it should keep my hunger at bay better than some things I eat (like bread, pasta, or vegetables). The problem is, I have to eat out sometimes, as I work far from home, and it's going to be hard to find pure protein to eat, especially when you need to know the calorie count.
If anyone has any suggestions for places to get high-protein meals out and about, let me know.
