Welcome to the group. Can I just say congratulations on only gaining 2kgs during your pregnancy, that is amazing!!!
I know exactly how you are feeling and we must share the same mind as I think like that also. I used to go to Weight Watchers meetings with my best friend and we both felt the same way as we were only 17 and 18 at the time. There was the different groups there also like a "posh" group, the "do I really have to lose anymore weight" group, the lifetime achievement group and then us. I think the next youngest would of been about 15 years older than we were and I found it soooooooooo intimidating. We both felt the same and got to a point where we'd eat really well and exercise during the week, then go for the weigh in and spend our meeting time at McDonalds instead. Kinda defeated the purpose really so we stopped going altogether.
I found I was comparing myself to other woman all the time and although I've seemed to talk myself out of that most times, I still have my days where it all seems too hard and I think to myself "it's just a dream, I'll never be a nice weight". The thing that gets me the most is I have a younger sister who can eat anything that she wants and never gains the weight but never ever judges people by their weight, she thinks all women are beautiful in their own way. She's three years younger than me and used to stand up for me when I was being teased.. go figure!! Then I have an older half sister who is obsessed with her weight and biatches when she hits 48kgs and goes on a strict diet. I spent mothers day at her house holding myself back from pounding her into the concrete with the way she was going on about her weight and how she has to lose it because it's disgusting being overweight and making comments like "I don't know how anyone can let themselves get to a state of being overweight, it's disgraceful and extremely ugly"..
Anyways, I've kinda gone off track here, sorry about that! As the other guys and girls will tell you on here.. "slow and steady wins the race!". Don't make huge changes because you won't stick to them (well at least in my experience I've never been able to!). Small changes last for life because not only does your body get used to it, so does your mind. Healthy eating, exercise and lots and lots of water really are the "magic" combination I feel and aiming to lose between .5 - 1kg a week is a healthy way to go. To help with me not comparing myself to anyone else, I placed a photo of myself on my fridge at my biggest weight, and I took a photo the other night of me now (which is on the forum). I have printed that photo and placed it on my fridge next to the other one and I can see the huge difference the almost 30kgs lost has made. It's my motivation now and with the help of these wonderful people I know I can lose the other 50 odd kilos to get me to my ultimate goal where I will be fit and healthy. I hope you can find that same inspiration and I'm sure in here, everyone will be able to help you with locating it!
Good luck with your weightloss and I look forward to following your progress.
