The main thesis behind Why Women Need Fat (out this month from William Lassek, MD and Steven Gaulin, PhD of the University of Pittsburgh) is super fascinating and builds nicely on the Fat Trap business we were talking about yesterday: Your body fights weight loss tooth and nail because evolution has found fat to be quite handy in a survival of the species sort of way. So I went ahead and blogged about all of that on Never Say Diet.
But, full disclosure: I haven’t read the book yet. I’m still waiting to get a copy into my hot little hands, so I had to restrict my analysis to the unfortunate, red flag-waving subtitle (How “Healthy” Food Makes Us Gain Weight and the Surprising Solution to Losing It Forever — oh boy!) and, more encouragingly, the way Dr. Gaulin describes their research in this Salon.com interview.
So I’ll be back with a more in-depth post about the book itself once I, you know, read it. Ahem. Yes, tireless and thorough reporting is what you can expect around here.
In the meantime, let me clarify that I’m not blaming Gaulin or Lassek for the subtitle. My guess is that was the publisher’s doing, as part of their “now this is how you sell a book about evolutionary biology!” strategy. They’re probably not altogether wrong either. But it does put the researchers between a bit of a rock and a hard place because they are simultaneously trying to explain why we’re probably all supposed to be a bit fatter than the Beauty Trap (and the diet industry) allows — and yet also, that we’d all weigh less than we currently do if our diet wasn’t so heavy in highly processed omega-6 fatty acids or “bad fats.” (There’s another red flag.)
Depressingly, I guess that sounds about right: Continue reading
