Despite the popularity of green smoothie cleanses, I would not recommend using this recipe to replace your meals. So the short answer is no! Smoothies are a great way to get a variety of fruits and veggies in one sitting, but you do need to actually eat them as well to get the full health benefits so that's why I never recommend doing any sort of smoothie "detox" or "cleanse". Your body does a great job of naturally detoxing on its own (read more on that here). Deprivation is never healthy. Make good food choices, and you can reach your health goals without resorting to unhealthy solutions.
