I DO still hide food, but I hide it from myself... If that makes sense! If I buy cookies, I have to put them in my desk drawer rather than leave them on my desk because I know I'd eat them all. All the chocolate I brought back from Belgium went in a drawer not in the kitchen, so I was less likely to eat it in the middle of the night!
I used to hide my eating sweets when I was a kid from my mum. I used to be always sneaking out to the shops and eating the evidence before I came back. She caught me once and said, "You're only cheating yourself..." WTF??? I was a CHILD! I shouldn't have been on a diet anyway! I think having those foods "restricted" at the time probably led to further issues. Even now when my parents came to stay just this past couple of days I stuffed my face like there was no tomorrow... I think it's defiance! "Look mum, I've lost TONS of weight and I'm going to eat like a pig in front of you!" I think that's what it's about really. I'd never really twigged until now... Food for thought!
Sorry for the ramble!
