There are specific nutritional requirements we must eat each day in addition to fiber - protein, fat, carbs, vitamins, minerals, and phytonutrients. Planning an all NutriBlast diet would take some careful planning and should be reviewed by a Dietitian. We encourage one Blast a day. Some drink it as a meal replacement and others add it to their regular meals or as a snack. This depends on your daily caloric needs and they ingredients used in your recipe.
