Context: In fact , an empty stomach starts to feel like a friend in an odd sort of a way . So , anyway , the days on which you eat are called " Up Days , " and the days on which you fast or eat / drink less than 500 calories are called " Down Days . " I decided that since I did eat some solid food yesterday and last night , I \'d make this first day on the " Alternate Day Diet " a Down Day . So today , for example , I started out with 9 or 10 oz of fresh squeezed orange juice and a couple of slices of dried apple . Before Sherry and Devon came over to walk , I made myself a lemonade like the ones I drank for the fast / cleanse .
