Anyway the reason it's so surprising is that I had a really bad month in terms of diet. I had several takeaways and went out for a few day trips. I even had pizza. I ate badly. Like, so badly I can't put it into words. I really got away with it last month but I can't do the same this month. Time to rein everything in and eat properly again. If I lose four pounds despite my best efforts I should lose a lot more when I try.
