Who wouldn't be aggressive and defensive about it? Since you speak English, statistically you are extremely likely to live in a society that likes to blame e.g. rising health care costs on "fatties", that fudges health analyses to ignore that being "overweight" by the usual standard is healthier than being "normal", that is full of people claiming that you are weak willed and "just" need to radically change your life forever to meet with some preexisting beauty standard. The mere fact that you can claim what you do in your first paragraph means you have never seriously had to deal with these problems. Some people are genetically predisposed to being heavy. When I was 16 and swimming over a mile every day, I weighed 220 ("BMI" claims that the maximum permissible weight at my height with a "heavy" build is 180, FYI). Trying to be 180 would do me far, far more harm than being heavy would, or will; this, too, has been backed up by medical studies (see: miserable effectiveness of dieting. See: health complications from losing and gaining weight.).
