I'm doing a 5 day meat and egg fast to get myself into ketosis and I got lucky because crab legs were on sale at the grocery store. I just looked it up and it says that crab is 0 carbs. The cool thing is that the crab meat is sweet, so it is kind of helping with the fact that I'm craving something sweet. Also, it helps with the overly greasy feeling that meat can give you when you get too much. I'm thinking I will make it 5 days, but I can't wait to add back in the greens!
