Ladies- changes in your period???

So I'm on the pill, and therefore very regular. I'm not due for another 3 weeks. On Monday, I started eating Tim's way. On Wed, my period started. And its not following the same flow pattern as I usually do. Did this happen to anyone else?

Thanks!

I don't think 2 days of eating the slow carb diet would be enough to trigger your period. Leptin, a hormone produced by fat cells, is thought to trigger the onset of menstruation. According to the book, the cheat day binge can temporarily increase leptin by 40%, and triggered menstruation again for one reader whose had stopped as a result of not eating enough fat. From personal experience, mine came right on time after eating slow-carb for about a week.

Wow, I'm so glad to read this post. For the females following this regime, Tim didn't give us any warning about what might happen to our monthly cycles. I have been on the regime since late December 2010 and previously had very regular 28-day cycles. The first month, my period started 3 days early and was more heavy than normal. The second month, it arrived another 3 days early. At this point, I am now experiencing a 22 day cycle instead of my previous 28. Other symptoms during my cycle have not been elevated; no increased moodiness or irritability.

I have heard this might be due to all the extra eggs the diet calls for?

I realize there was no way Tim could have tested for this?!? I am very curious to hear about other women's experiences on the regime.

Okay, I've had just the opposite from everyone who has posted so far. I am usually like clock work when it comes to starting. I've been on the 4 hour program for 3 weeks now, and my period is now 5 days late. I have the bloating, the backache, and the weight gain as I always due right before starting but that's it...

    Me too this month. I have been on SCD for about 5 weeks and last month my period came on time as usual. This month it came 5 days late. I have always had perfect 28 day cycles. First time for me and I am 37 years old. I am hoping "fat loss" caused it :-)

    wow, that's why I'm reading... same thing exactly! @_@

  • Leogurl commented Jun 18th 2012:

    I just got over the same problem but my period finally showed up exactly 1 week late. Some member suggested I take potassium but I've been taking potassium for awhile so I decided to start eating a little fruit everyday in conjunction with my slow carb meals. I'm not suggesting you do the same but I lost 6lbs last week so fruit hasn't been a problem for me. Good luck.

Who knows with me, since I am beginning menopause, but I can tell you that in the 9 months before doing SCD, I'd had only 2 periods. Thought I was done, or close to done. 7 weeks into SCD, I'd had 3 periods already; they were short and light, but still it was odd. I figured it was because I was FINALLY getting enough iron --- I've always been borderline anemic. I'm eating tons of spinach, eggs, etc on SCD that gives me a lot of iron, so I figured my body was thinking "Well, I guess we don't have to horde all the iron now and can release some." Simplistic, I know, but it makes sense to me.

After a couple of weeks on SCD, my period came 7 days early. I'm not on the pill though I'm pretty regular every 26-28 days.

So this was a strange occurance for me. I can only put it down to diet...

I had an IUD inserted in December. My period is going nuts right now, but I don't know if it's a hormonal thing cause by the diet, or a mechanical one caused by the IUD.

  • serv84 commented Feb 17th 2011:
    Not the diet. I got an IUD in Sept09 and I had exactly 6 mos of the WORST periods, heavy beyond belief, cramps like contractions, and my face broke out into cystic acne that left my formerly beautiful skin a red, scarred battlefield. Hang in there!

I was on the pill and the same thing happened to me when I did the introductory phase of south beach diet. (Almost the same as Slow Carb.) It went back to normal after that one time and when I asked my doc she was not worried.

Same thing has just happened to me. I'm suppose to be getting it next Thursday and it started today. I'm happy to hear I'm not the only one with this happening.

I found this on a website:

Diet

A change in diet could explain an irregular menstrual period. When your diet drastically changes, for better or worse, your body will react by preserving energy. One way it can preserve energy is by ceasing menstruation. Once your diet balances out and you are eating healthful meals, your menstrual cycle should even out. Consuming too few calories can lead to menstrual irregularity and sometimes you will stop menstruating altogether. Eating disorders like anorexia and bulimia wreak havoc on all of your body systems.

I've been on this diet for 5 weeks now, the first period was late by about a week. Since then, the past 2 weeks in a row, I get a short, small "period" for 1 day--on my cheat day...then it goes away...maybe the fat is forcing a menstruation? it goes away before I'm back to the non-cheat day though?!

Same here. 3 days into it, my period arrived early (Wednesday instead of Saturday). 5 days later... I'm still bleeding. I even had to use tampons.

My period before this was usually 1-2 long and so light I didn't need anything to protect my clothes.

However, I also changed from Yasmine to Melian this month, so I'm not going to blame it entirely to the new diet. I'm giving it 2-3 more cycles before deciding if it's got anything to do with it.

I've only had the opposite happen. When I was doing the Atkins diet and exercising for 45 minutes every day, my period stopped altogether, which is really bad (it can permanently thin your bones). It's caused by caloric deprivation and/or fat deprivation. That's why doctors have to sometimes prescribe “the pill” to vegetarians to initiate menstruation. So unless you were starving yourself and then binged for 2 days--which I doubt if you were following the slow-carb diet--then I wouldn't worry about it too much. In fact, I'd say it's probably a good thing. A few things I found while researching this for you:

  • Only 10 to 15% of women have cycles that are exactly 28 days
  • The menstrual cycle is triggered by the hormones Luteinizing hormone (LH) and follicle-stimulating hormone
  • Your diet does effect these hormones (In a study with adult male rhesus monkeys, 1 day of fasting leads to a profound suppression of LH secretion that was rapidly reversed with refeeding).

yup. on the pill. yup my period showed up a whopping week early and has lasted extra long while being super light. i didn't think it was related to the diet but after reading this now I guess it is... good to hear that it should return to normal next month? it is, however, making weight loss excessively difficult. i don't appear to have lost anything in my 3 weeks on the diet, but it's hard to tell since 2 of those have been period related!

  • jaimidaw commented May 24th 2011:

    I'm not on the pill and just started this diet and am on day 9, But after my 5th day, I got my period early, It didn't last super long, But I thought that was strange.... Must be the diet...

Same thing happened to me! After 3 weeks on the diet, my period came one full week early. And I'm on the pill, so that's quite unusual for me. My period has also lasted *6 days* and has been very heavy -- not typical either. It didn't even occur to me this may have been due to the diet (I thought maybe it was the pill).

Another interesting note -- I lost almost 9 pounds in the first 3 weeks, and since my period (which started a week ago)… nothing! Here's hoping this is a short-lived plateau.

Anyway, great to see all of your responses… really appreciating this makeshift support thread right about now. Good luck to you and your periods!

This is my 18th day on the diet, and I just started my period. It came right on time (I'm not on the pill), but my PMS symptoms were abnormally bad.

Two days ago I was a crying, emotional mess. One day ago I had cramps that made me double over in pain. But today the period started & I'm feeling ok. It's amazing to see how much our diet affects every other aspect of our bodies!

Mine has lasted longer and cravings about a week prior have made me break the diet every day. The weird thing is, it is easier to stay on diet once I start and I have lost the most weight during those weeks. Granted, only 2 months for examples but I thought it strange. Anyone else lose more weight during period?

  • Skittles11 commented Mar 28th 2012:

    I'm on the pill, and my experience with that and the diet was that it came on time but was lighter than normal. Im not complaining :) I also didn't gain much water weight while on it either. It lasted for 5 days and was definitely not my usual 7 day heavy period.

I hadn't even thought about how this diet might affect my periods...for the better, I hope! Usually I have very heavy and painful ones for 7-9 days, and my cycles can go from anywhere between 28-32 days (I'm not on any birth control). Thanks everybody for sharing your experiences--I'm due next week, so we'll see what happens! :s

I was up half the night googling what might be wrong with me! I'm two weeks into the SCD... my cycle came right on time but was extremely heavy. Being on the pill, this is way out of the norm. Yesterday was my binge day so I guess that's what caused it. Breathing a little easier now.

I’m so glad I found this site! I started the SCD about two months ago and my period has been all over the place (on time and fine the first month, spotting, then short and super light, then 4 days of spotting and this month no period). I’m on the pill and this is really abnormal for me. I seriously thought I might be going crazy thinking something was majorly wrong! I read the same thing about incorporating fruit and sweet potatos back into my diet, so am going to see how that goes this month.
