I'm adjusting to solid food after completing 12 weeks of Optifast liquid diet plan. I'm able to stay within my calorie range just fine, and my fats, carbs and fiber are also within range. But I seem to fall just a bit short on the protein almost every day. Is there something I can eat other than a slice of cheese (I don't really need that extra fat) to bump my protein up just a bit? I'm already using 100% whole wheat bread and pasta and brown rice. I need to know what else there is that's a good source of protein. Thanks ahead of time.
