I’ve been doing alternate day fasting for about two months. I find it very easy. In several ways it’s easier than eating every day:
- save time
- save money
- less constrained on eating days
- a little more hungry than usual on fasting days (up to a point hunger is pleasant — when the Shangri-La Diet wiped out all my hunger, I didn’t like it)
- sense of accomplishment when I wake up after a fasting day (I did it)
- food tastes better
Maybe my friends are unusually tolerant but I have yet to encounter a serious negative. Yesterday, a fasting day, I happily watched a friend eat dinner. I had two bites out of curiosity. I saw nothing to suggest it made her uncomfortable I wasn’t eating.
However, a different friend has told me that alternate day fasting made her sick. She did it for about three months, felt worse and worse, and finally stopped. She believes it works less well for women than for men. I suspect a heavy exercise routine (she ran a lot) made alternate day fasting more difficult. But there is also the best-selling book The FastDiet. It has two authors, a man (Michael Mosely, a doctor) and a woman (Mimi Spencer, a journalist). The book contains a remarkably short and remarkably unenthusiastic description of Spencer’s experience with intermittent fasting. Maybe it didn’t agree with her, either.
