Most of my problems aren't about portion control, they're about being completely out-of-control. Bingeing, picking, feeling lonely or depressed and eating the fridge, that kind of thing. My portion sizes for my meals are fine, but I struggle to control my other eating.
If I keep crisps in the house, for instance, I will sit eat them until they're gone. If I buy cakes for a treat, I might eat all of them so no-one else gets one - or even worse, go back out and buy some more to replace them. I don't only eat at mealtimes, and I don't only eat when I'm hungry.
A typical morning's binge for me might be five packets of crisps, a couple of chocolate bars, a couple of pastries or cakes, several rounds of toast, half a packet of biscuits. When I'm struggling and bingeing, I can easily spend £10 a day on food just to shovel in and hide the evidence from. When you can pack that away, portion control isn't going to do you any good at all. Even when I'm not bingeing, if I buy a multipack of crisps for dd, chances are I will sit and eat them all myself and then hide the packets so no-one knows I've eaten them.
What I'm trying to do is address the reasons why I eat that way, and do something about them. Work out what my triggers for a binge are, and avoid them, try and let myself believe that it's safe to keep food in the house and not scoff it all so that it's not there to worry me any more.
I only eat that way when I'm on my own, so when we sit down for a meal I can quite easily control my portion sizes and be satisfied with what I've got (although I do like my food, and if it's in front of me I'll eat it, no matter how large a portion it is). When I'm alone I can be completely out of control - and hide all evidence of it. I think I have the root causes of my eating problem sussed - but so far I haven't fully worked out how to overcome them. I'm starting to get somewhere with it now though, and hopefully these threads mark the start of a whole new relationship with food.
Standard diets don't work for me because they don't address any of my "ishoos" - all the portion control and willpower in the world isn't going to beat my weight problem. I can lose weight on diets, but I've realised that until I address the root causes of my eating problem it won't go away - which is why when I've lost weight on standard diets before, it all comes back and brings reinforcements with it.
