The secret to losing weight and building muscle? According to Nike trainer Marie Purvis, one thing is key: "Thirty grams of protein within 30 minutes of waking up." Easier said than done, but if you make this smoothie recipe from actress Jennifer Aniston, you're one breakfast down to weight-loss success. Jen loves this recipe because it resembles a milkshake but doesn't skimp out on the nutrients. With over 30 grams of protein and 10 grams of fiber, it'll leave you feeling full and energized straight into lunch!
