From John Hann
I can personally vouch for the efficacy of the 5:2 diet, in which you strictly limit calorie intake two days a week (17 November, p 46). After two operations for cancer at the beginning of this year, plus a warning over kidney function, I adopted this regime.
After just over two months I was told I would not need to be prescribed statins, and my blood test results were much improved. This was very reassuring to an 80-year-old.
