yes its a very good lean meat will help build muscle and keep you full. i assume you are also working out rugularly with a cardio and weight training schedule?
adding some is fine, moderation is key. if someone looks at your plate and cant decipher what kind of meat is under all that then there's a chance that there's too much on it
i do about 3-4 chicken breast a week, put some cajun seasoning on them and grill 'em up
