I don't take it as disrespect. And the reasons why we all struggle vary with region, culture, genetics, family history, and other factors that are too many to put here. In my case, I'm calling "genetics" as a heavy hitter for my struggle, as there's a very strong thread of addiction on my father's side; we're talking 4/5 of the generation before me being really active alcoholics, major food-addiction issues, gambling, bulimia, etc.
I know exactly how many calories are in every piece of food you can put in front of me. I just eat too many of them, too often, and struggle with the compulsion to go get more and eat that, and then obsess over wanting more. Unmedicated, I simply never stop thinking about food, and the struggle to only eat a reasonable amount in a day takes all of my focus and all of my energy, and I've never won it for more than a few months at a time.
