I get the point but...
When you're a woman and well over 100kgs, don't complain about your doctor telling you that you need to lose weight.
It's not sexism
It's not discrimination based upon your weight
Nobody is telling you that you're ugly
It's not a macho thing where only skinny women are desirable
It's about your life, how long it will last and how much you'll be able to enjoy it. It's about your own health, please listen to your doctor and try to lose weight.
