Hi, there are no rules as for what or when you eat on your DD's, the diet is actually based on alternate day fasting so its perfectly acceptable to have nothing on your DD's, so eating later in the day is absolutely fine. I don't actually eat on my DD s as I find it easier not to, the time I was eating was getting later and later and in the end I thought why even bother, so I don't . I have milk allowance of 150 cals (skimmed milk) which I have in tea and coffee throughout the day, cal free soda and water. It doesn't speed up my weight loss or anything like that it just makes DD s easier for me, as soon as I eat the hunger pangs start, if I don't eat I don't get hunger pangs.
Ruth has lots of food on her DD s take a look at her diary x
