I am no coach, but even if not on a diet and sick, just liquids to let the body heal is good. I don't think this is different. Lots of water, warm lemon water, ginger tea, (use only appropriate sweeteners) AND HOMEMADE CHICKEN STOCK, best cure all! You can puree steamed veggies into it. Vanilla chai pack hot, chocolate shake, for protein. I also like the yogurt berry drink pack. But seriously, real chicken stock.
