Hi Muppeteer. When you say that your mum has always been 'anti fat' , am I correct in assuming then that your mum has a figure to die for ? Lucky her if she has but she is doing little for your self esteem by dishing out crushing comments. Have you told her how upset it makes you when she passes comment in this manner ? Perhaps she feels that her comments are designed to give you a kick up the backside and will motivate you to lose any excess weight , not realising that instead of benefiting you , her comments are quite soul destroying. My dad really crushed me a while back when he said to me "I used to have such high hopes for you but it seems that all you're good for these days is churning out babies." It was apparently meant to give me the kick up the backside I needed to pick up my studies again. I did (not for my dad's sake , for my own) but I was devastated by that comment and felt so worthless. So much so that I blurted out my anger and distaste at that comment months later , much to my dad's horror. He hadn't realised how much he had hurt me and was genuinely upset at having hurt me so much. Perhaps your mother doesn't realise how much her comments hurt you and that far from assisting your weight loss , it is making you comfort eat.
Are you trying to go solo in losing weight ? Perhaps you would benefit from joining a slimming club in your area where you could get proper nutritional advice and regular weigh ins. It takes a long time to put on a lot of weight so obviously it takes time to take it off again. Just go at your own pace and work towards realistic goals. It's better to work towards smaller goals rather than thinking in terms of stones you want to shift. Aim for a few pounds at a time and see how you go. Exercise is important too. If the gym is not for you , then go out for walks. Nice and easy to start with and then you can gradually increase your speed until you feel able to go jogging and/or running.
