This is quite interesting as it seems like most people who are naturally thin don't enjoy food for the sake of food and just see it as fuel.
Meanwhile, I'm a massive pig. I eat at least 2,000 to 2,500 calories a day and often more. But, I also exercise an insane amount.
When I stopped exercising - after quitting the sport I'd done at a v. high level for years - I piled on the weight. I couldn't eat less as exercising 3-4 hours a day since I was 14 meant that I was just used to eating lots. Psychologically I was still hungry, even though I didn't need the calories and I ended up getting far too chunky (and then depressed, which made me eat even more). Eventually, I just accepted that in order to keep eating the amount and the type of food I enjoyed that I needed to exercise even if I wasn't 'competing' anymore.
So, I do at least 2-3 hours of good, hard, exercise a day - whether there's hiking along the beach, swimming or running. I work full time and go into the office two days a week and my hours are typically very long when I do go in (out the house for over fourteen hours). I have three kids and a dog. Life is busy. But every day, regardless of whether it is raining or 30+, I exercise because I like food.
I eat whatever I want. For example, today I've had a pain au chocolat, club sandwich (with three tablespoons of mayonaise - and not the low calorie crap either), three lattes (12oz, full fat milk), and dinner will be steak, bearnaise sauce, a jacket potato, asparagus, broccoli and peas. I'll probably have some mango and a slice of cake for after. But I've also done 3 hours of good, hard, exercise (admittedly, I am on my NWD so today is particularly good for both exercise and eating a lot!)
