I commented on this blog post, but now want to comment additionally. I'll do it over here, since it is long, something I had wanted to say for awhile, and BECAUSE I WANT TO LEVERAGE WOO'S POPULARITY AND DRIVE TRAFFIC TO MY BLOG!!!! (Guess at least n=2 on that plan, judging by the other visitors there.)
First a little note about Dr. K and his battle against IF. I have read him since the beginning, and even though it wasn't 5 years ago, he has always warned people about IF. He says that people who are leptin resistant shouldnt IF. He is the only person in the whole paleo cesspool who ever gave any kind of explanation for this, and then later Stephanie Ruper did a post where she outlined some of the problems with women doing IF. Her explanations were insufficient (and she might reconsider renaming her blog to Paleo for young women).
MY blogpost about it is here, of course with confounding factors. My take-home clif-note version for my own situation is that I used to do IF and it worked, and then after menopause, along with a typical calorie-reduction plan recommended by [redacted]people, IF was a disaster.
This came up a few times on Paleohacks, with first a tepid response, and then a full-scale, jihhadist, lemming-like, mass-downvoting extravaganza by all the Wolf-pack and their extremely disrespectful zealot brofriend WOD-podners. ("Oh, we can't let her get away with posting that HERE, now that the top dog in the Wolf-pack even put IF in the TITLE OF HIS BLOG!!")
Maybe Dr. K's explanation is wrong, too, but he was the only one at the time honoring the anecdote. And, despite his posing, his revisionism, and his insane current marketing plan, I have never seen him waver on the IF prescription. And that is, "NEVER NEVER NEVER until leptin sensitive." BTW, you do not have to purchase any supplements or webinars to get the information about Kruse's leptin reset.
At good time to add, I guess, that Dr. Rosedale also has a plan for making one leptin sensitive again. And, despite what many tater-eatin' carbbists say, you do not have to eat any expensive supplements in order to do it. In his book, he clearly explains uses of the supplements, and how to do it on a budget. None are essential. I got his book for free at the library.
