Being fat makes them sick which makes them move less which makes them more ill. A cursed circle. How good is life if you can’t move? Then you are confined to a bed waiting for death way before your time? How about watching that happen to someone you love? If someone got into car accident you would take them to hospital, not say “you are beautiful just the way you are” and expect to get better on their own. Obesity is illness that kills (no matter how slowly) and should be treated as such.
