Birth control and weight gain - myth?

I definitely think birth control makes some women hungrier, but from my own experience, it doesn't cause me to gain weight or give me any issues losing it. I don't know a lot about it to be honest, but I doubt birth control has a significant impact - I don't understand how it would make your body gain weight, unless you did start to eat more because it can temporarily increase your appetite.

Just realised you're talking specifically about the implant. I only know one woman who has used it and kept it in (I know a few people that it caused constant spotting in so they had it removed as soon as they could), and she has actually slowly lost weight over the last year. Very small sample size though, of course.

Lots of women believe this but as far as I am aware no properly conducted clinical trials have ever shown it to be true.

I went on the birth control pill at 16 due to endometriosis...
And I weighed maybe 98 pounds soaking wet back then.
Within the next 6 months I gained about 10 pounds. Over the course of the next couple of years I struggled to keep my weight the same.
Then the winter after I graduated I was switched to a different pill that affected my body horribly, I was depressed, hungry, and tired all the time. Over the next 6 months I gained another 20 or so pounds.
I don't believe it was only the birth control that caused my weight gain, but I do believe that it probably aided in my weight gain.

The reality is (or the reality as based on poorly conducted studies) that there is a correlation between certain forms of BC and weight gain. However, the caveat here to look for is this; the weight gain, if due to hormonal changes, should actually stop within the first month of the 'new' hormonal balancing. And what we eat, has a hell of a lot more to do with weight gain than either hormones or BC.

If you switch (to any new medication really) watch your calories carefully and you should not see weight gain (beyond water weight, which again, would leave within that first month).

I have friends who have made the BC adding weight claim many a time, but the reality is, we all started taking BC at a time where our bodies were in big fluctuation based on puberty. I put on about 15lbs the year I went on BC (I was 13 and had some significant issues with cysts) that was however also the year that my boobs went from a A cup to a D and my hips began to fill out, so chances are, even without BC, I would've put on that 15lbs. I switched briefly to NuvoRing (sp?) in University which created some interesting bedroom issues, but no weight gain. Switched from that to taking pills consecutively in three month periods (medically advised, again because of the cysts) and gained maybe 3lbs? I also redeveloped a love for McDonalds that month, so I'm more blaming that on my own poor food choices.

So the reality, is it a factor? Sure. Is it one completely out of your control? (With the exception of a bit of water weight initially) No.

I think for me it comes down to this; if you get new BC and suddenly you're a lot hungrier than usual, but you know your TDEE is typically a certain number, continue to eat at a deficit, and magically, you will lose weight. If you're hungry so you add an extra 500 cals per day and don't notice, and your TDEE is only 400 cals higher than what you're eating, of course you're going to see weight gain over time.

Make good choices, my BC switching friends.

It really sucks being a woman sometimes hahaha!
I wanted to get the coil but the doctor won't let me. She said first of all that it would be harder since I'd never had kids - fair enough. Then she said that the coil may affect my fertility long-term so she couldn't give it to me.
The problem is, I don't want to have kids. I have never wanted to have children. I explained this and she said I may change my mind.
I don't know why doctors can't accept that some women are simply not maternal. The reason I want birth control is so I don't get pregnant. In my case, that's a permanent decision.
Thanks for your input guys, it's interesting. I think the hormonal changes may cause the weight gain.

Just to add, I do think it's unreasonable that your doctor is overruling your wishes on the presumption that you may later change your mind about children - especially given that the coil is not an extreme or permanent solution.

The most recent studies seem to suggest that correct use of IUDs doesn't have an impact on fertility. I say 'correct' because there is a risk that if you get an infection (which usually occurs within 2-3 weeks of insertion and impacts under 1 in 100 women) then this might cause damage if untreated - but that's why they now do post-insertion check-ups to prevent this.

I have three sisters, all of whom were on birth control at some point. Of the three only one didn't gain weight (at the time she was very strict with her diet, though). The other two gained a substantial amount of weight primarily because it increased their appetite. My younger sister gained over 20 lbs in a few months the first time she started taking them because of that. The weight fell right off when she stopped.

When I got the depo shot I gained like 40 lbs in just a few months, plus I turned into a crazy person. My moods were all over the place, it was scary not feeling like myself, just horrible. I did two rounds of it then stopped and went back to pills, and everything went back to normal.

From what I've heard from doctors and friends is that the increase in hormones that prevent you from being pregnant also sometimes causes you to gain/lose weight. When I first went on the pill, I lost weight. But when my insurance got messed up and went off of it for a couple months and back on it but a different brand, I gained weight. I just went off of them, and I can already tell I am losing weight again.
