It is true though. And I say that as a fat person, (although not as far as I was 2 years ago).
It's not one choice though, it's a million of them, every single day. Shall I have that biscuit, shall I go for a walk. Yes, food noise is a thing, but giving into it is a choice.
I spent the better part of a decade "trying" to lose weight, and instead getting slowly bigger. And then about 20 months ago I developed a black spot in my eyesight, along with a couple of other symptoms. Blood test at the docs, and yep, properly, scarily type 2 diabetic. Faced with the possibility of losing my eyesight, suddenly it was a lot easier to make different choices and I lost 40lbs in just over 3 months. No weight loss drugs, just choosing not to have that biscuit, not get a meal deal, go for that walk, only have 1 beer.
I've had normal blood sugar levels for a year now and I can feel myself slipping, it's getting harder to make the good choices when the consequences feel more distant.
So yes, some people have it harder than others. Some people have no trouble making the right choices, whereas some people find it almost impossible difficult.
It is, still, a choice though.
