I saw a horizon programme about 2 or 3 months ago about the effect of diet on ageing, & have been following it since. It involves eating normally for 5 days a week, & then having just 500 calories for 2 days out of every week. It`s supposed to help with high cholesterol, & the doctor fearured who tried it had some good results after 2 months. I don`t know if it`s doing me any good yet, as I decided to give it about 3 months before having a blood test to find out. I`m just wondering if anyone else has tried it & had good results?
