The main difference between being sick is the energy to prepare for low carb, I think. It is a lot easier not to prepare foods from scratch and just open a can of soup. Not to mention these foods are comforting. My best advice is to always have foods that are palatable at any time (broth, favorite veggies, already cooked chicken) on hand when you're sick. Cracking an egg into broth makes an easy egg drop soup and ups the protein as well. Anyway, I wish all those sickness sufferers luck. It is hard for me as well. And if you do fall off, don't kick yourself, just jump right back on!
