The simple answer is no! Meal replacement shakes help you manage your caloric intake throughout the day and ensure you’re getting balanced nutrition while you’re cutting back calories. In most cases, in addition to your shakes, a healthy meal will be needed to meet your body’s total requirements. We recommend replacing 1-2 meals each day with 310 Shakes, which contain 110 calories per serving of balanced, whole food nutrition. Our shakes are thoughtfully designed to be low in calories to give you the flexibility of adding in your favorite fruits and veggies to make your shake a crave-worthy meal every day.
