I used to have this viewpoint but now I'm ashamed of it. I'm athletic, and my body weight tends to stay the same no matter what I eat and how much I exercise. I've gone on serious binges just for the fun of it and not gained a pound. I've also gone through days of food poisoning without noticing any significant drop in weight. I now make an effort to eat healthy, not because of weight but because I think it's the best thing to do for my body and future even if I don't see any difference at the moment. Sure, calories in and out matter, but it's very clear to me that the human body is complex, and if someone else has a body that reacts similar to mine, only with a significantly higher normal, I feel very sorry for them.
