I have just returned from our road trip. My wife and I departed from our diet for 9 days. She gained only about 5 pounds and I gained 10. I'm not sure how much is water. The key lesson that I have learned from this is that when I officially leave the diet, I should ease off of it rather than going cold-turkey back to my old lifestyle. Also, I am hoping that this break has reset my body's resistance to low-carbing so that I will realize the initial rapid weight loss often associated with the first few months of low-carbing. Only the next few weeks will tell.
