Like it was said before, beef can be healthy. Chicken and turkey tend to be leaner, but they are lower in protein. If cholesterol may be an issue, see how much fiber you are getting in your diet, and eat more fiber.
I, too am a student, and I work full-time+ Here's my general plan (I drink water with all meals, except for breakfast, when I have fat-free milk): For meal 1 (breakfast), I have a cup of oats, with fat-free milk, and a scoop of protein powder, with some type of fresh fruit, usually bananas. For meal two (3 hrs. after meal 1), I have a piece of whatever meat I am eating that day, along with about a cup of veggies, and a fruit. For meal 3, I have some more of the same type of meat, with some type of healthy fats (uncoated/unsalted nuts, olive oil, etc.), and about a 1/2 cup of veggies. For meal 4, I have some more meat, with some fruit, and less veggies. For meal five, I have mostly meat. For meal six, I only eat meat or protein powder w/ water, and some cottage cheese-it helps to keep muscle growing while you sleep. Oh, and about 45 mins. before workouts, I have a scoop of protein powder with some fruit. After workouts, I have my PWO shake, which is made up of 1 scoop protein powder, 1/2 scoop creatine, 2 tsp of BCAAs, some maltodextrin, and this vitamin c powder that I got from Mexico. You can cook on a Sunday, and cook enough for the whole week, then put everything in tupperware, and throw it in the freezer.
