I'm not a huge believer in low-carb diets, but, I do very much believe in choosing "good carbs". High fiber carbs are, actually, very healthy for you, and can be an important part of your weight-loss plan.
There are 3 types of carbs -- starches, sugars and fiber. It is good to avoid starches and sugars (the simple carbs, refined carbs, and starchy vegetables) However, carbs with high fiber are good for you.
I am very much a believer in the calorie cycling concept of the JUDDD diet, because of the way it "changes things up", and varies our calories on a regular basis. You can also "change things up" by varying the number of carbs you eat per day. It would make perfect "dieting sense" to choose to eat more low-carb on your UP days, as you asked. Then, on the days when you choose to include more carbs in your diet, make them high fiber carbs.
(I start most mornings, for example, with oatmeal. I often snack on oil-popped popcorn -- not the microwave popcorn with lots of hydrogenated oil/trans fats. I eat very few products with white flour -- very few crackers, bread, baked goods, pasta, very little white rice, and very few starchy vegetables -- potatoes and corn.)
As I said, I am not a big fan of low-carb diets, but, I do believe in choosing my carbs carefully.
