I continue to be fascinated by this thread. There is so much insight here.
My situation and past experience is very different from what most of you are discussing here. But the more I think about it, the more it makes me wonder about when and how such seriuos food issues start. Mostly because I never want to end up in that boat.
I haven't been that active on the forum for the last few years, but those of you who remember me from before may remember that I was a fairly serious Ironman athlete. One of the interesting things about Ironman is that when you are training that much, you eat a ton. In retrospect I think I was actually eating too much a lot of the time during the week. On long workout weekends, it's pretty hard to overeat. I never lost a lot of weight training for IM. In fact sometimes I would put weight on. But I never worried about it, I just assumed that my body would adjust and I would eat what I needed.
Fast forward to about 1.5 years ago. I put on about 10 lbs after IM, during my recovery season, and it never really came off last summer. I was just riding mostly. This winter comes and I put on another 5 lbs. So come January, I was the heaviest I've ever been and activity modification was not doing the job. You can only increase your activity level so much when you're already really active to begin with. So I decided that I would start tracking my caloric expenditure and intake very closely and try to run an appropriate 20% deficit per day.
What an eye opener. I've lost 10 lbs and I have another 5 to go to get back to my fighting weight so to speak. I am amazed at how skewed my perception of what a healthy portion size was and how little I actually burn on that run or ride. But what's getting me now is that I do not want to be obsessed with what I eat. I don't want to feel like I have to record every little thing. It just doesn't seem psychologically healthy to be preoccupied by it. I want food to be joyful and not conrtolling.
So what I've done is kept track of my eating and exercise during the week, but on the weekends, I let it go. I'm not doing as well with my weight loss as I was, but I think I'm OK with that, because I don't want to be obsessed with it.
I'm not fearful that I will go down the obesity road, or that I will end up with an eating disorder. But I wonder if that's how it starts for some people.
