Healthy Shake Ideas
I've already mention smoothies in the Breakfast menus, but they are also great for snacks, midday meals, or recovery drinks after high intensity activity.  The key thing with shakes/smoothies is to have them do what you want.  Really you want to watch content % of calories to protein, carbs and fats and total amount of calories.

Fruit smooties - recipe: 12 - 16oz of filtered water or non-fat milk or other low fat non-dairy milk (rice, soy, oat) 2 – 3 scoops of protein powder (ideally high quality whey protein, you can use vegetable protein powders as well). ½ - 1 cup of fresh or frozen (unsweetened) low glycemic fruit.  Add 2 teaspoons – 1 tablespoon essential fatty acid (flax oil, Dr. Udo’s blend, or flax meal) or a favorite nut or seed. You may have noticed options for amount of protein, liquid, fruit and oil; this has to do with caloric requirements of your smootie. If you do not know how many calories you want to be consuming for each "meal", use this BMR and RMR calculator to get an idea. Check estimates based on activity level. Calculator.

Veggie Juice and Spirulina - Okay, only the true health fanatic can suck this one down, but I thought I'd put it in. 6 oz veggie juice, 2oz filtered water, 1 teaspoon spirulina. Chug. Spirulina is one of the worlds most vital foods. It is the most complete source of all the amino acids your body needs, plus it's green! Try adding it to your smooties for extra health benefits.
