Fasting, particularly the type known as intermittent fasting, has been popular in many health communities for awhile. Many people learn about it through Mark Sisson, Leangains, or Eat Stop Eat. Some people do it for weight loss, other people do it for its other potential benefits such as boosting cellular cleanup known as autophagy.
I read an advanced copy of Why Women Need Fat when I was moving and because things were so hectic, I didn't have time to review it before it was released. I haven't heard that much about it though, except for this interesting interview with one of the authors in Salon. It's co-authored by Dr. William D. Lassek and anthropologist Steven Gaulin.
I was going to just do one big post on this subject, but the amount of information out there is so extravagant that perhaps I'll do several. I suspect this topic doesn't get much air because well, most bloggers don't want to relate personal anecdotes. And really, there are no really good solutions to this issue.
I said I'd go to bed, but then I read something interesting. Lately there has been some discussion in the comments here about what level of body fat is healthy for women. Is it healthy for women to be as lean as men should be (below 18% body fat)? Some authors say yes. After all, don't women in third world refugee camps have babies all the time?
