Indeed - I was very active, I worked as a gardener, garden designer, did a couple of days in a tree nursery as a propagator and also had my own wholesale herb nursery. Then ten years ago we moved and not only did I live in a flat for a while as we waited to buy a house, I also acquired arthritis in my hips, then gradually elsewhere. My weight ballooned as I found it hard to realise that what I had been eating before was thousands more calories a day than what a suddenly inactive person should be eating. It has taken me years to work out how much I can eat, and how to get enough nutrients into that very small amount, and how to make myself feel full on it. It also made me realise how little I knew about diet. And that if like me you are almost incapable of moving during cold winter months, 2000 calories per day is about 500 too many.
