Just done day 1 of 5:2 and man it was tough!! Hadn't eaten since 8.30 pm last night all the way through to 6pm this evening, surviving on herbal teas and black coffee. I woke up hungry so that didn't bode well but I survived. Just had chicken stir fry for tea which came in at 432 cals and will have a bag of salt and vinegar ringos at 65 cals once my kids are in bed. The weird thing is I feel almost just as hungry post dinner as I have all day - maybe I should have chosen something with less carbs and more protein? Does this get any easier?
