It is weird - all the time I keep working out, for the past 2 1/2 months, I noticed that my weight 'never' reduces at normal times, and as if an accumulated effect, the weight goes down suddenly at TOM by as much as 5 - 7 lbs! And then again, I have to wait till next TOM for the next set of weight loss although I work out consistently during the inbetween weeks. What could be the reason for this? Anybody think of any reason?

I don't know, but I noticed the same thing, so if somebody knows, it would be awesome to find out what's up!

Actually, this past month, I went back to WW from CC and I've been losing pretty steadily every week, so I wonder if I won't get my period-whooshes or what this month.

This topic has come up before, and while most women posting notice a cycle-based pattern, there seem to be a variety of common, and not-so common atterns.

Some research indicates that metabolism imcreases during tom (but for many women, so do cravings, hunger, and water retention).

I tend to gain 5-7 lbs of water weight a few days before and a few days into tom. If I don't give in to pms/tom hunger and cravings, I will lose really well the week after tom, and fairly well the week after. During pms/hunger (7-10 days), my hunger goes haywire. I feel half-starved no matter how much or how little I eat, even when eating low-carb (which normally curbs my hunger fairly well). Low-carb helps some during the hunger phase of my cycle, but not as much as during other phases of my cycle.

It is a weird phenomenon. I lose consistently through the month, but I'll lose 4 pounds in a matter of days during TOM.

I personally think (for me) it's due to an increase metabolism combined with the absence of other period symptoms. I don't bloat, nor do I have an increase in hunger/cravings.

Same here ladies! For years and years...

My hunger is out of control the week or so before TOM, then after it gets here, I see a small loss, then within days after its gone I lose anywhere from 5-7 pounds. Its frustrating because if I didn't eat so much/horribly the week before TOM I'll see a really big loss... but most of the time, basically all the time, I pretty much binge the whole week prior, sometimes even 2 weeks. Sometimes I PMS from ovulation until TOM. And like kaplods said, it really doesn't matter what diet I follow, I do low carb as well to control cravings, and it helps the rest of the month, but TOM it barely puts a dent in my eating/cravings. I find "ways around it" and will over at other foods, though I do prefer carbs and sweets.

I wish there was a way to stop it though. I know it slows my weight loss and as I get to lower weights it basically stops it. At heavier weights, I seem to be able to handle the extra calories without too much effect, but I remember last time getting into the 150s and even 140s, those 5-7 days of over eating really set me back, and I'd spend the rest of the month losing the pound or two I'd gain at TOM.

I've never thought of it being about metabolism but just water retention. I always notice increases in weight in the week leading up to TOM or maybe more and then i get the whoosh thing.

Anyway its all good if your weight keeps going down month after month isn't it.


Just got this from herehttp://www.betterhealth.vic.gov.au/b...luid_retention which is a government health website.

and this which suggests that metabolism slows not speeds up during menustration so then its got to be all about water retention in the end. http://www.ncbi.nlm.nih.gov/pubmed/7124662
