I've recently read a number of articles on the benefits of intermittent fasting (specifically, 24 h periods of fasting rather than Ramadan-style daily cycles of eating/fasting).
In animal models and in some limited human trials, alternate day fasting seems to have an effect on type 2 diabetes, cardiovascular disease, cholesterol levels, oxidative stress and cancer. Most interestingly to me, it appears to be a better alternative to calorie restriction for weight loss/fat reduction. I'd rather not eat for a day than constantly be holding back. (if you search Google Scholar for "intermittent fasting" you get lots of interesting results.)
I've started trying out once-a-week fasting, but I'm hoping to increase it to twice a week (more doesn't look feasible with my exercise/work schedule).
Has anyone tried it? Everyone I've told has been flabbergasted at the idea of me not eating for any extended period of time.
