I feel like the author is generalizing by assuming that everyone who is fat has an "obsession with food".
I can say that my feet, knees and legs sure appreciate the change. I definitely don't feel that weight on me like I did before. I do like the occasional "Hey, you're looking good" or "You lost weight, didn't you?" That doesn't offend me. My facial structure looks better, as I have a better chin line now. My clothes are a pain, as I have to keep a tight belt as all my pants are too big now. My stomach is much flatter and doesn't poke out. Hah. I don't have a 6 pack but I sure don't have a mini-keg starting.
Anyway, after all my rambling, my point is that I wasn't addicted to food. I just sit in front of a computer too much, and was consuming too many calories. I do miss fun food. I haven't had things like ice cream since I started this thing. I'm not a fan of always being hungry. I deal with it, but I sure feel like I can eat all the time. The key is to just not think of it. Avoid being around it. I don't go out to eat with people, as that stuff is always a killer when it comes to calories. Usually, I meet up for a drink but when they all decide to go hit a table for dinner, I'll say my goodbyes and move along to something and eat later at home as I know what I'm ingesting.
For most of us that have too much fat on us, it's simply about calorie control. It's not food addition, or a mental problem. It's simply awareness. Though, in the US, we obviously have a huge mental disorder epidemic, but I believe that is just the disorder of "rampant cognitive dissonance." It covers so much of our issues here. "This soda is fine, I only have 4 a day." "Sure it's deep fried, but it's fish and that's healthy!" "He's a billionaire; he doesn't want your money! You can trust him to fix the government..."
