I think that Brightonrosie is absolutely right. I did post myself about something I had read that had given me a light bulb moment last week... about the importance of controlling sugar in our diet. I have started to do this and this week I've lost nearly 1 lb (0.9!). This week I'm afraid is going to be difficult because TOTM is coming so I feel like a balloon, but I'm sure that as soon as the *ahem* technological problem will be resolved, I'll keep on losing. I have also noticed a better regularity *there* since I started eating less sugars, which obviously helps weight loss, as it means that the digestive system is working properly.
of course I don't give up sugar completely: every evening I have a dessert and I also have chocolate porridge and 120ml of orange juice in the morning, and on Sundays and Wednesdays and alternated Saturdays (my days off work, when I have a brunch rather than a breakfast and lunch) I'll have also at breakfast 2 slices of Irish soda bread (lower in sugar) with reduced sugar jam on them. But I have basically cut sugar from anything else, except of course fruit and vegetables.
I'll see how it goes in the next couple of weeks. I have found a Greek natural yoghurt with no added sugar which I'm having every day as well at breakfast. I finely cut a small banana into it and after a few stirs and a few minutes resting it's not too bad to eat

The good thing is that it's only 1pp per 100g and it keeps me full for longer than having breakfast with only my usual porridge, egg, banana and orange juice.
