Technically, yes. Protein bars, have additional vitamins and minerals in addition to protein so you would be able to survive off of them. However, this is not something I would suggest. Protein bars are processed, and also contain additives and preservatives in addition to nutrients. You definitely need to add fresh fruit and vegetables to your diet, as well as other sources of protein such as fish or lean meat.
