Our flat-belly smoothie has become all the rage for good reason! The Greek yogurt in the recipe provides calcium and protein, both of which can aid in weight loss, and it also contains several ingredients — like blueberries — which have been shown to help diminish belly fat. If that's not enough, you also get the sweetness of pineapple, which contains an enzyme that helps ease digestion and banish bloat. You won't be able to taste the kale, which is full of fiber to prevent constipation, as well as calorie-free water to help clean you out. And of course, it doesn't hurt that it's so refreshing, filling, and delicious.
