I never claimed that I was losing fat - just that my weight was reducing by a kilo a day. I had to up my carbs and slow it down after only a few days as I was not safe to drive.

My metabolism is not raised by exercise, as my thyroid is kaput. I take the tablets each day and that is all the thyroxin I get.

The dietician at the clinic I attend was addamant that all I needed to do to start to lose weight was to eat fewer calories, and week on week reduced what I was supposed to eat until I could not cope. It was, of course, my fault that her diet didn't work and I did not lose any weight.

All my life I have been considered overweight, I was fat even as a baby as I was fed undiluted sugary dill water to keep me quiet in the night, as we shared a house with family. It set me on course for a lifetime of bad advice on how to eat.

These days I am just happy to be able to control my weight.
