Do you have a link for IF messing up hormones so we can get some context and vet your source?7

Why would IF mess up your hormones?3
-
I keep seeing this pop up. Does anyone have concrete sources/research on this? I don't do IF but I am very curious if there is any truth to it affecting hormones in women.3

You do realize that everyone intermittently fasts, right? If you were to skip breakfast, which is one of the more common things to do, you would likely only be adding 4 or so hours to what you do normally.6

This is nonsense. Everyone "fasts." Some people just fast longer than others.8

Why on earth would someone "woo" someone for asking a question and trying to get more information?
@sanda4930 I did a search, and yes, there is a bunch of stuff out on the internet about IF and hormones. I just did a quick read through, and of the information I saw, there was some research out there about hormonal changes during IF, but, and that's a Sir-Mix-A-Lot sized but, many of the hormone claims I saw were kind of tangentially related. It was a lot of "we know xyz hormones show changes based on this actual research, and we know these other hormones have a connection to the xyz hormone changes, so we are saying these other hormones are showing changes as well." I didn't see a lot of research showing an actual researched correlation.
I wouldn't worry too much about the hormone aspect unless you have a medical history of issues with hormone changes, in which case you should be talking to your doctor. Even if you are observing some changes when you start IF, there are a lot of different protocols out there you can try, it's not a one size fits all.18 -
I've done intermittent fasting for 6 months through the program Faster Way to Fat Loss and have not had any issues at all. My biggest advice is to make sure you get good quality food during the time you do eat, and hitting your macros in the right proportion.5

I'm sure I once saw a link on here saying that women are better off doing 10/14 but I can't find it anywhere...1 -

I thought the same and am relatively certain I saw it on Lyle McDonald's site at one point but I've combed the site to look for it but can't find it.

I believe it was also the OP. But I've seen it mentioned several times by many different people.
I do remember Lyle McDonald mentioning something in his women's book about fasting leading to some issues in women but he did mention there was limited research @KickboxFanatic and @TavistockToad3 -

It was a couple of years ago I first heard it... I'll have a Google...2 -

Martin Berkhan talked about it as part of leangains but I believe that was based on his work with women, more so than actual research.1 -

I would guess that people are trying to express that they don't believe IF has an impact on hormones, but that's just a guess. Since you can see the who hit woo, you could PM them and ask.
OP, this:TavistockToad wrote: »
suggests that the science is not yet transferred to people. Unless you have some additional information that we could look at more closely, I wouldn't worry about it at this point. If you have medical conditions that may be influenced by IF, then I suggest seeing your doctor and asking for a referral to a Registered Dietician to ensure you are meeting your medical needs along with your nutritional needs.5 -

Thanks @psuLemon I will check it out.
I think at the end of the day if you are fasting as a female and you notice your cycles or stress levels being affected, I would reconsider or experiment with decreasing the fasting window. I am sure there are many variables and there is no strict guideline, just as I would imagine how leanness and bodyfat% will affect women's hormones at different levels.2 -

I don’t fast (except for religious reasons, so not daily), so I have no real horse in this race, but I did stumble across this article the other day that may be helpful

Check out the section under Intermittent Fasting May Affect Men and Women Differently. Not sure if this information is correct but they included links to their source of data.0 -
I saw from your other post, OP, that you want to lose without counting calories. Can I suggest that you not use IF as your method of creating a deficit unless you're maintaining at your current weight? I've had success with IF and counting calories, and I have definitely gained weight while doing IF when not paying attention. A shortened eating window won't work if you're still eating too much. The magic is in the calorie deficit, you've got to figure out a good way for you to create it.5
