NutriBlasts can be used as a meal replacement if you put the right ingredients in it. Be sure to include all 3 macronutrients like carbohydrates (vegetables and fruits), healthy fats (nuts, seeds, oil), and protein (nut butter, seeds, nuts, protein powder). Make sure it has enough calories to fit your needs. I would suggest that in addition to your Blasts you make one meal a whole food meal that you can chew. It may be worthwhile to meet with a local nutritionist/dietitian so that he/she can help you create recipes that are suitable for a meal replacement and suit your needs.
