Why Girls are loosing weight?

I am also shedding weight, I know it's such a great challenge for most of girls, well, everyone, including guys. But what made us to torture ourselves so impatiently and restlessly?
Normally people shed weight through the following ways: diet, exercise, medicine, drug, operation or sickness. well, the last one is not optional, he he.
Most girls would say that they would shopping without limitation, none would tell them: sorry, lady, we don't have bigger size for this dress...so embarrassing.
I don't want to be asked if I am pregnant or not anymore...also embarrassing.
I don't want to be heavier than my loved one. Who protect whom?
I don't want to be the fattest in the TV show. Well, if you're just fatter~ it's another thing.　
Because I cannot put on sporty Jacket! Who forced you to wear it?
I just want to proof to everyone that I am not born to be fat!- Yes, you deserved it.
I want to feel more comfortable! - I suggest you get more money, this is better!
I am jealousy! - it's not good lah　　
I just want to show myself it's cool! -it's cool?!　　
I would know how will I look like if I am slimmer?- stupid!!
For job, for love, or for whatever reason, well, except health. Loosing weight is not really a cool fashion to follow, it's dangerous somewhat. How many people are so much readied as to read all the medical care before taking the operation?
I suggest people don't shed weight so blindly. If you're convinced to do so, please make out a plan and follow well base on your health.
