Batch cooking is where it’s at, y’all. Make a couple of big multi-serving recipes of good stuff the weekend before the first day and fridge it or freeze it in portioned servings. Choose something that you’re already somewhat familiar with and strip all the carbs out of it. That doesn’t mean just no bread or rice or pasta, btw. Fruits and veggies can cross into dangerous numbers as well, as do pulses, oatmeal and legumes. Use an app like MyFitnessPal or Fat Secret to tally up all the calories and carbs and determine proper serving sizes. A lot of folks aim for a top limit of 50 grams of carbs a day. I go way lower than that (less than 20 grams a day) to combat insulin resistance, but whatever you choose, choose something. Picking your carb celing is a good anchor point to help you get a grip on the process.
My first week on the BSD I ate chicken salad — baked chicken breasts, full-fat mayo, a squeeze of lemon juice, a small green onion, fresh parsley, fresh thyme, salt, pepper — on a bed of greens for every lunch. I just scared up a big batch of it on the first day and weighed out 4 oz onto arugula or romaine lettuce until it was gone. The week after I switched it up to tuna and egg salad with roasted red pepper (just half of one because they tend to be sugary), garlic and cumin mayo. Again, something I’d been making for years.
For dinners your easiest bets are soups, broth based, not tomato (also sugary), omelettes and srambles, fish fillets that can be baked in the oven wrapped in foil with assorted veggies, or even smoked fish that doesn’t need cooking at all. Some of my favorite soup options are cauliflower and blue cheese, zucchini with masses of cooking greens like broccoli rabe, chickory, escarole, endive, chard, turnip or mustard greens, and the easiest of them all: miso soup so full of multiple kinds of sprouts (broccoli, alfalfa, pea, sunflower) that you have to eat it with a fork before you can sip the miso-delicious chicken broth.
You do not, I emphasize, do not have to go miles outside of your comfort zone. You just have to replace some of the old ingredients with other ones. Look them up ahead of time to avoid any nasty surprises because innocuous seeming veggies can deliver a shocking carb hit. Onions are hugely high in sugar, for example. It’s not about complexity of cooking. It’s about knowing what you’re eating and how much of it so you stay within your 800-calorie and self-determined carb limit.
