We as a society are fat because we have too great and easy access to food
If you overeat you become hungry quicker and it takes more food to stop you feeling hungry. If you don't eat much anyway then actually it doesn't take much to be full.
For example when I ate when I was hungry and i was 16-17 stone, I could easily go back to a buffet for seconds or thirds and still be hungry enough to eat dessert. I lost 4 stone and I found one visit to the buffet unbearably full, in fact i coildnt even manage the breakfast buffet the next day.
If you are fat, listening to your hunger will do bugger all, your body has already learnt to overeat.
If you comfort eat, but only have access to one carrot, you can only comfort eat that one carrot. You are unlikely to become fat.
If you comfort eat have access to a packet of bakery cookies, a Chinese takeaway, and nice bread, you are likely to become fat.
There was an argument in parliament that after ww2 ended rationing should actually continue because it was actually good to restrict access to food for the general population. For course business not health won that argument.
For those of us who naturally eat beyond the needs of or body, weight maintenance is likely to be a constant struggle. I ended up losing around 6 stone with my fitness pal. I'd never have lost that weight without it, I like food, I like fatty food and yes I comfort eat. And yes I kept (most of) it off for around 6 years. But I only did that because I kept mfp and about every 4-6months starting logging again to reset my diet and my appetite
Mfp is a way of resetting the body cues when they have gone wrong.
Yes I'm back up to 15 stone now. I know full well its because I have had a shocking year and I comfort eat. I can be mindful of that fact all I liked, doesn't mean at that point in time I was ready to stop. I could mindful of only eating when i was hungry, but if my body was still telling me I was hungry after 3 Christmas shortbread biscuits and another 3 might do the trick Listening to my hunger really wasn't doing much good.
Weight loss and management is a precarious balance between emotion, motivation and physical cues.
