People are jerks. If your weight bothers you, you can go to your doctor to talk about weight loss options
Trust me you do not want to be anorexic, I had anorexia (not Anorexia Nervosa or Bulimia) induced by severe nausea caused my h pylori infection(it's not fun) I had malnutrition, I felt like I was going to die, my hair was falling out, I became bed ridden, and I quickly gained the weight back after treatment of the infection.
besides my short bout of anorexia I was obese most of my life, about five years ago I decide that my weight was ruining my life and that I would make a change. I have at this point lost 60 lbs. I eat 4 large vegi based meals a day, I get at least 30 g of fiber every day(all from food), eat at least three cups of vegis and three whole fruits, I don't drink calories and I exercise for at lest an hour a day (I stared with just walking and now I'm doing HIIT, weight lifting and jogging.) losing weight is not always how much you eat but what you eat.
