The case against Intermittent Fasting

Answered on August 19, 2014

What types of people should not do IF? And in what ways (if any) can IF actually have a negative impact on health?

Toni- Yes. I would not do it yet. CFS can be a number of things, but you are dealing with imbalances, sleep, fatigue, adrenal problems, whatever, and it's all taxing on your hormones, including thyroid. These problems tend to run togeher. Get that fixed first. I don't believe the claim that IF automatically fixes hormone problems or improves them just due to IF. It may be the case for a Paleo Robustus, but if you have CFS, you have some work to do first.

I'll comment that while I do IF and like the freedom you get in your noneating window, towards the end of those 16 hours I do feel my body temperature drop.

Are you saying that those with chronic fatigue syndrome should not IF? Please clarify! Thanks.

Yeah, I always baulk a little bit at IFing for myself because of a history of eating disorders in my early teens. It's not the same, but it still gives me the same feeling, which makes me nervous. I think there is something to be said about the mental component of IF- it can be an excuse to abuse yourself if you aren't doing it for the right reasons.

My thinking was more of long-term health issues-thyroid conditions and eating disorders come to mind.

That's the best time to listen to your body. If you are sick and not eating, that is hardly what most people mean by "IF." IF is getting too much credit here! All of a sudden, missing breakfast because you got up late is this trendy, hip "IF" thing.

How does that fit in with loss of appetite type illnesses? If the body's natural response to compromised health in some situations is to fast doesn't that suggest that we don't need to be *too* fearful of it?

I believe I have undiagnosed thyroid issues (used to have all the hypothyroid symptoms), and I can assure you that IF is not good for me. I get pale and weak from it, I get constipated from it, I sleep really bad, ... Zero carb has the exact same effect, and VVLC is 10x worse (because veggie fibers actually make me hypoglycemic faster).

I've heard it can cause excessive cortisol levels in some individuals and/or if done to extremes, and that women should have longer feeding windows for some hormonal season if doing daily IF - haven't bothered to do research on either since everything is going fine and I'm a male. 59 weeks on IF, 16 off, 8 on, every day.

If you IF to lose weight, make the checklist first.

Checklist for IF, in my humble opinion-

  • Do you have thyroid or chronic fatigue symptoms, or meds for these?
  • Are you doing this out of desperation? (for obese, not meant for gym types desperate to drop the last half point in body fat!)
  • Do you have a history of yo-yo dieting?
  • Is your energy low or you wake up tired?
  • Are you doing leptin reset one month and IF the next? If so, try not to be so trendy! Next month you will be carb-loading with the elite!
  • Are you putting pressure on yourself to make this work? (Let it come to you, don't force it.)

Overall, it would be nuts to say that humans are not equipped to IF. Nature provides. But, Paleo theorists always talk about the ideal human, and Paleo drs talk about real humans now.

I try and look at these memes through that lens. These sites are a mix of advice for the ideal human (or the very robust and fit Paleo leader) and people with a lot of problems, often serious, and they are just looking for help and picking up advice they don't need at the time.

The recent swing in carbs upward is like this I think. The longer you do Paleo and refine it as a fit person, the more you figure out how to add some carbs. Wow, all of a sudden, the fit folks are all about more carbs. Always read the fine print, if there even is any!

I have a history of binge eating and there were many warnings that I shouldn't try IF. BUT, when I thought about it I realized the only time in my adult life I didn't struggle with binge impulses was when I just ate 1 meal per day for 6 months (and lost 50 pounds.) When I reached my goal weight I found I was pregnant and went back to eating "normally" and that was the beginning of my yo-yo pattern. I temporarily lost the weight several more times on 2-3 meals per day but always succumbed to binge eating at some point.

I can see that IF won't work for all binge eaters because we all have different life stories and therefore different binge triggers. But, despite all the warnings about IF I decided to try it and I LOVE it. All my binge cravings went away and they only return under extreme stress. It's very clear to me that my natural eating pattern is once per day and forcing myself to eat more often because CW says I should is self-destructive for me.

My answer to this question is, if you eat a huge breakfast and don't eat until you have true hunger pangs (meaning your stomach is complaining, not your brain) the intervals between hunger will either drift farther apart over the course of a week or so until you are in an IF pattern OR they won't. If they don't, IF isn't for you. If they do and you feel wonderful, welcome to IF!

I think IF should be seen as more of a spectrum than a yes/no. Relatively few people people need to eat every few hours, to the point of waking up at night to eat. Very few people need to eat less frequently than every 48hrs. So that is, all things considered, a very narrow window. You might fall closer to every 3-4hrs, you might fall closer to 48hrs, but for most(not all) people, there's not a bright line in there. Not only does it depend on the person, it also depends on a huge amount of variables for each person at every given time. If someone is interested in IF, there's no reason not to ease into it. By doing so, they can determine where on the spectrum they fall.

People with compromised health, and/or under the care of a doctor should either not IF or do so with consultation and very carefully. Anyone who is not near peak condition should approach changes to IF, or any other lifestyle factor, with reasonable deliberation and caution.
