It's so delicious, and so simple to make, that you can have it as breakfast, a snack, a meal replacement, or even dessert! For Zero Belly Diet, David Zinczenko, co-author of Eat This, Not That!, designed the ultimate program for making your gut disappear. Each day, you’ll enjoy—and we do mean enjoy—a blended smoothie designed to complement the natural weight loss and lean muscle gain you’ll see from the Zero Belly program. Studies show that high-protein, low-fat smoothies are highly effective at rushing nutrients to your muscles—which is why Dave recommends you have your drink immediately after exercise—and that blended fruit drinks, which include all the fiber, will actually keep you fuller longer than fruit juices. Above, watch a video to get the recipe for his favorite smoothie, the Strawberry Banana.
