I'd like to thank you for posting this AMA, and to wish you luck in the future!
Do you have good time periods where you eat healthier and the weight comes off? I have those, then it goes straight back on again.
From your example daily menu, it looks like you are eating the wrong things. It's easy to do and underestimate the calories in an item, I was very shocked to discover the Greggs pasties have about 500 calories in them, but they feel like you have barely eaten anything. Have tried changing what you eat, instead of dieting? So switching meal types, instead of eating less, i.e. swapping the two pasties for two eggs on two slices of toast? I'm going to follow my own advice, my diet is rubbish at the moment.
