When I started 5:2ing I told no one including OH. But one fast day he made me lunch at which point I told him all about it, science and all but he was really critical of it all.
Many years ago he used to be a serious weight trainer, entering competitions, so (like most men!) he thinks he knows it all

. That evening I eventually found the Horizon programme online and we both watched it. Well, he didn't believe a word I said but was totally convinced by Dr Moseley!!
He immediately announced that he would be 5:2ing with me. Great I thought but he is a pain. On fast days he relies on me to tell in what he can eat, he constantly talks about food and keeps telling me he is starving!!! Its all about him

. It is good really because he is the type of person who when he decides to do something will stick to it which will keep me going.
My work colleague is highly critical of dieting including fasting when we chatted about it before I started but she often misses lunches as she not hungry - mmm, isn't that fasting! She will eventually notice my weight loss and be quite jealous then I'll tell her what I've been doing.
