How do i lose a lot of weight fast?

I'm 13 years old and (last time I checked) I'm about 175 lbs. However, I'm 5'9 and most people say my weight is normal for my height. But I really want to be skinnier because I'm tired of being the 'fat ass' at school. I am soo sick of not being normal...

weight like all of my friends. I want to be able to wear anormal bathing suit like everyone. And to be honest, I'm not buldgy and super fat or anything like that, but you can tell that I'm kind of chubby-ish. I want to lose 40-50 pounds fast because I'm going into high school in like a month and I don't want to be the 'fat chick' there either. I know the basic explaination for weight-loss is DIET EXERCISE... but it's soo hard to stick with it,and it's really hard to get motivated. I just really need advice.

Does anyone know how I can lose about 40-50 lbs. fast? (without diet pills, protein drinks, etc.)

weight loss does NOT happen fast
it happens GRADUALLY
and it can take months to loose weight and see results
not hours, not days, not weeks...MONTHS
healthy eating and regular exercise is the only right way to loose weight
anything else will either damage your health
make you gain all the weight back and then some
or do both
first you need to see a doctor and get your bmi (body mass index)
calculated for your height and age
he/she will tell you what weight range your in
and how much you need to loose if your not in the healthy weight range
then to start loosing weight work towards exercising for at least 30 minutes a day
and eat healthy
and try to switch any soda drinks, fruit juice drinks and energy drinks with water
because there all full of sugar
and remember
if you dont put in the effort your not going to see any permanet results
