I think that my appetite was re-set by a lengthy period of 5:2 eating. I now tend to just eat an evening meal on the vast majority of days. I am simply normally not hungry at all during the day, but I will adapt in order to fit in with whatever is happenning socially. I find though, that if I eat at lunch time I don't want to eat anything later in the day.
Fortunately, even when it is a" feasty" type of meal which I'm eating, I can no longer cope with the volume of food which I might have had in the past, but I'm finding that this way of eating is not resulting in additional weight loss. Now that I'd like to return to losing weight, I think that I will have to combine this approach with calorie counting to ensure that I keep to 4-500 calories twice a week.
