Fast Days Healing Days and Susie T. prove that 500 calorie, intermittent fasting FDs or DDs (Down Days) do not have to be boring, nor are they filled with deprivation. This fast day meal plan features 2 meals and dessert for under 500 calories. When springtime rolls around, it’s only natural to begin craving lighter tasting meals that don’t sit as heavily in your tummy. This FDHD Meal Plan is a perfect 5:2 Fast Day and also jives with a 500 calorie intermittent ADF style diet such as 4:3, JUDDD or EOD. Light zoodles or zucchini noodles combine with gorgeous pan roasted mushrooms, super greens and lemon for a filling and flavor-packed lunch. Dinner is more light fare that doesn’t feel like diet food: avocados, blue cheese, crisp veggies and leftover grilled chicken make a very UN-boring dinner salad. (Psssst: leftover meats are a lifesaver when living a healthy lifestyle–adding protein and flavor to salads, “pastas,” and soups in seconds–with little effort. And there’s ever room for dessert.
