Does anybody else only lose weight one week a month?

I've been dieting the past three months, and have lost a stone. Weird thing is, looking back through my happy scale app, I seem to stay the same weight (maybe going up a pound, which is gone the next day, but never losing any further weight) for 3 weeks at a time. Then the day before I come on my period, I start losing weight, and lose half a stone throughout that week. I can see this trend throughout June and July, and I've been stuck at 13st 5 for the past 3 weeks (sticking to my diet religiously, and going to the gym 3 times a week). Today, exactly 3 weeks later and due on tomorrow, I've suddenly dropped 3 pounds. It's so weird!

Feel a bit better now I've noticed this trend as I've been following the BSD principles which usually causes rapid weight loss, so get very disheartened during the 3 weeks seeing no difference on the scale. Have considered various reasons why, from eating too little and damaging my metabolism, to building muscle (joined the gym around the same time).

I've dieted on and off throughout my life and have never had this before. I've always lost weight pretty consistently and fast when I've stuck to a diet (but I also gain weight at ridiculous speed when I take my eye off the ball). I'm super motivated this time, and have completely cut out sugar and junk, am exercising regularly, watching carbs etc etc but I just don't understand why I only lose weight one week a month!

I've tried to google, and when I start writing 'only lose weight...' it comes up with a suggestion for 'only lose weight one week a month' so other people obviously have this issue, but I can't find any relevant stuff on the internet relating to it.

Has anybody else experienced this?

Hey. I know this is an old post but when I typed in google my dilemma, your question was the first to pop up!!

What your writing is exactly me 🥺 I can’t figure out why this happens and I wondered if you ever found out why it happens?

It’s extremely soul destroying but I’m going to keep going

No, seem to either STS or gain one week in four (and a big gain!). I'm assuming for me it is hormone related so maybe it's hormone related for you too, only the other way round? Have just said on another thread I need to get my head around the overall trend being what matters rather than individual weeks, and not let the bizarre gain (when I'm doing exactly the same in the other weeks) demotivate me.

I’ve been searching on the internet and you are the only other people I’ve found like me, I’m exactly the same! I try so hard during the month and nothing, then a few days on my period and boom last time was about an 8lbs loss, this isn’t from bloat it’s actual loss that stays off!
i literally can’t find anything on the internet about why this would occur at all. I noticed it when I was weight tracking, it’s really obvious. It’s like my body holds on to the weight until my period, it sounds crazy doesn’t it 🤔
