I'd say I have a 'normal' relationship with food and always have.
I weigh 9 stone and have done since the 1980s with no conscious control of intake. Since the menopause I find I want less to eat. I chuckle at the posters who talk about 'competitive undereating' when they describe quantities similar to, or greater than, I would eat, want to eat and maintain my weight on.
I don't think about food much and am surprised when people try to engage me in discussions about it, or describe some dish or recipe. I'm just not interested. Obviously I have to choose in the supermarket, but tend to just pick a few things I fancy, put them in the fridge and eat them in date order. I eat when I'm hungry, which roughly co-incides with breakfast, lunch and dinner. If I'm not hungry I don't mind missing a meal. OTOH, I eat what I feel like and don't deny myself anything. My body tends to tell me what it needs - I sometimes get a huge desire for red meat, and have been rejected for blood donation due to anaemia around then.
I do like fruit and veg and easily have 10 portions a day. At least half of my lunch and dinner will be veg, with fruit for 'pudding'. I prefer a lot of vegetables raw to cooked.
I absolutely hate feeling 'stuffed' and find a plateful that is too much quite off-putting. I know I can leave part of it, but I'd rather not be faced with it in the first place.
Sometimes it seems to me that I enjoy food more than some of my larger friends. I've particularly noticed if we're sharing a box of fancy chocolates - I am still licking the remains of my first from my back teeth and enjoying the sensation and taste, while they are on their second or third. I don't want the whole experience of my first disturbed! This is also true of any tasty dishes. The reverse is true - I can open a packet of, say, crisps, have a few and then get fed up with the synthetic flavour and put a clip on to finish them another time.
Growing up we were very hard up and meals tended to be small and rather strange. Potatoes, cheap vegetables and offal featured. We certainly had to clear our plates; although my parents never said, I was aware that they found it hard to put food on the table and heartbreaking if it was rejected. I was often hungry but I survived and don't fear hunger the way I've noticed some people do. My grandmother grew a lot of fruit and vegetables, so when we stayed with her I enjoyed them freshly picked in unlimited quantities. We only had treats occasionally, so they really were treats. If they had the money we would have ice cream for pudding on a Saturday and two squares of chocolate on a Sunday evening. I don't enjoy a big slab of chocolate nowadays like I used to enjoy the Sunday night treat.
