Whenever you break your fast, be sure to do it slowly. Your insulin and blood sugar will be low. Your ketones will be high. Your stomach may have shrunk, and your body will be producing less digestive acid. In fact, much of your G/I tract may be taking a nap. Start with some soup or bone broth, then some vegetables, then meat and all the rest. In fact, you can simply follow the order of a multi-course meal: soup, salad, entrée with vegetables, dessert. Just spread out the first two dishes to give your system time to warm up.
