When trainer-to-the-stars Harley Pasternak shares a recipe, we're definitely making it. His 5-Factor Diet, after all, has helped both Jennifer Hudson and Jessica Simpson drop major pounds. So when Harley tweeted this simple recipe for a smoothie, the next day's breakfast was a go.

With only a handful of ingredients needed, it's deceptively simple to make and big on protein, calcium, fiber, and vitamins — the perfect way to start a morning. The smoothie itself has the perfect amount of sweetness, and the tiny addition of cinnamon gives it a spicy kick. It's almost like having apple pie in a glass — except this meal will keep you full until lunch! The added bonus of this recipe is how easy it is to build upon; add spinach, kale, or berries to the mix to really amp up the antioxidant power.
