People who are new to Fasting often pose the questions: “Can I really eat ‘anything I want’ on a Slow Day?” and “What should I eat on Slow Days?” To answer those questions, I have decided to add some blog posts to show some of the foods we eat on what the world calls NFDs [non-fast days] but which, in our house, we call ‘Slow Days.’ This feature will appear sporadically.
Now for the answers. Can you really eat ANYTHING you want on a Slow Day? Not really. If you eat too many calories every Slow Day, you will not lose weight. There are many questions asked on the Fast Diet Forum which attest to that. Once in a while you can splurge, as long as it isn’t everyday. For what to eat on Slow Days, Dr. Mosley recommends a Mediterranean Diet. As for how we eat, an example follows.
Dear Husband, growing up in a Catholic household, ate his mom’s tuna casserole a lot as a child. On Fridays, of course. I, growing up in a household with a father who avoided fish, never ate tuna casserole. A few years after we married, Dear Husband said, “Let’s have tuna casserole this Friday!” Since I had no idea what he meant by that, he prepared it. Out came a can of cream of mushroom soup, out came a can of tuna, out came the macaroni noodle box, and soon the meal was done.



He loved it — I thought it was awful: salty, stodgy, boring. Years later, Dear Husband suggested that we try it again — but with improvements. #1: instead of canned mushroom soup, homemade Béchamel Sauce with added wild mushrooms. #2: instead of canned tuna, fresh tuna from the fish market. #3: instead of simple-carb-refined-flour noodles, homemade or purchased whole wheat noodles. Now we were cooking!


Every year, we prepare this dish for the first Friday in Lent. Since the sauce makes enough for four servings, we bake half of the recipe with noodles and freeze the remaining sauce-tuna to prepare two weeks later, with the addition of freshly-boiled noodles.
