Having been fat, overweight, obese, thin then fat again, I'm now thankfully slim.
Yes you are right, fat people are treated differently. My life is much nicer now I'm slimmer, I don't get stared at, I don't get strangers calling me names. I've almost forgotten what is was like to be fat.
I feel a little sorry for fat people because I know how hard it is to lose weight and the bigger you get the harder it is to lose.
The worrying thing nowadays though is, it's almost encouraged to love your fat body, enjoy all the food and sod the consequences.
