I have struggled for the last 11 years with my weight.
At 16 I was 9st 6lb and a size 10 (at 5ft 2.5). I got pregnant, and after I had my son, I weighed around 11st 7. I had actually lost 2 stone when pregnant, and only put that 2 stone back on by full term (hyperemesis for 22 weeks). But I put over 2 stone on after I had him.
My weight crept up, and then down for a few years. 7 years to be precise. I am not 100% sure of my biggest weight as I refused to weigh myself, but it must have been somewhere between 15-16 stone and a size 18-20. When DS1 was 7, I split up with his father. Then began the misery diet. I quickly (over 8 months) dropped a lot of weight, probably around 4 stone, and went back to 11st 7. I was a 14, and finally happy with my weight. I had curves, and felt great. I would have liked to lose more, but didn't really put any effort in.
When I say the misery diet, what I mean is that I was so fucking lonely, and down, I couldn't eat. I'm not a comfort eater. I'm a comfort starver
. What was the point in cooking meals for myself anyway? My DS1 had to stay at my mothers a lot due to my shift work, so many days I didn't eat a proper meal. I would still eat shite, take aways and mcdonalds. But the weight dropped regardless.
Then I met DP. I swear to god he is a feeder. He really is. He was 10st when we met, and soooooooooo skinny it was unreal. He did need to gain weight. But he has just tipped the scales at 15 stone!! 
When he moved in with me (April 2010) he put 4 stone on in 6 months. Not good at all. He was doing a lot of the cooking. And he had the my! money to go food shopping, so he was buying us all kinds of treats.
For a while I managed to keep the weight off, but then it slowly increased again. By the time I was pregnant this time last year I was 14st 4lb. I didn't gain a single pound during my pregnancy. 2 weeks after I had him in November, I weighed myself. Still 14st 4lb. At my 6 week check I was still 14st 4. So then at around 15 weeks PN, I was back in clinic (on going issues with episiotomoy) and was weighed. I was 16 fucking stone. In 9 weeks I'd put over 1 1/2 stone on.
That was a kick in the arse. I ummed and ahhed over what to do, how to lose it. I realised I actually felt unfit for the first time in my life. Despite being fat, I've always been able to run about and keep up with everyone. But I don't feel that way any more.
Anyway, I joined slimming world 11 days ago. I've lost 10.5lb already.
And I'm finding it easy! For what it is worth I've never done any proper diet, never done SW or WW or anything. So fingers crossed, this will continue!
DP is doing it with me and I think he has lost 7lb in the same time. He has also stopped snoring, and sweating at night! Bonus! Oh and both of our skin has cleared up from spots!
