Protein Shake Liquid Diet. The protein shake diet isn’t a traditional diet, which requires you to give up your favorite foods and subsist on bland meals. Meat and fish may be liquidised in soup, stock, gravy or thin sauces.
If you are on a protein shake diet, adding a healthy meal or two is an excellent choice. Add adequate liquid of your choice, blend well, and strain. Make sure you consume protein, carbohydrates, and healthy fats at each meal to help with nutrient balance.
