Although I highly suggest patients avoid eating at fast food restaurant chains, there is bound to be a time when you are stuck in the drive-thru line at McDonald's. Whether your spouse sent you on a run to pick up dinner after a long day at work or you are road-tripping it, I want to make sure you are well equipped for whatever circumstances you find yourself in. So I have reviewed all of the most popular fast-food chain's menu items to find the most protein-packed, low carb options for you.
