Smoothies can be an adequate meal replacement. However, in order to ensure that it is a healthy replacement, you must go beyond just blending up some fruit and vegetables. As Time reports: “a well-rounded smoothie usually has 1 to 2 tablespoons of fat, 1 cup of fruit, a handful or 2 of greens and 1 cup of protein.”
TIP: To make your smoothies into a full meal, add protein powder and/or some sort of nut butter, such as almond butter.
