What's a good gauge for that? Well, a 3-oz piece of meat has approximately 21 grams of protein. So if you eat two pieces per day, you're almost done with the amount of protein you need daily! AND if you limit yourself to only one piece of meat daily, you're leaving more room on your plate for other good sources of protein like milk, yogurt, and beans (which are high in fiber and GREAT for your heart).
Tip: Try going vegetarian for one meal.
