    Why would IF mess up your hormones?

    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.

    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...

    There's another thread on the go that sounds suspiciously similar to this one.

    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 @TavistockToad

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

    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.

    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.

    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.

    Based on my experience, the first time I practiced IF during Lent 2009, I lost 17 lbs. in 40 days not counting calories. What I learned from that experience is how hard it is to eat the calories one can eat in a normal eating pattern unless you're practicing gluttony. And, if you are practicing gluttony, you're not going to achieve weight loss no matter what eating schedule protocol you follow.

    There are some credible studies, in my opinion about IF that don't involve rats. I've shared at least one in the past, one that involved men who regular lifted weights for strength training. I read the study carefully and thought it was convincing pro-IF. Of course, there are studies that support the opposite. It's the nature of research and will always be.

    Bottom line, it's rather easy to eat less with a restricted feeding window, unless you're a glutton.

    What have you found in relation to women's hormones?

    I need to know too.

    To add, I am not a glutton. What do you mean by glutton? that is a derogatory term.
