I want to loose at least 2 stone as fast as possible, help?!

I want to loose at least 2 stone as fast as possible, help?

Hey. I'm a 13 year old girl (very mature looking and acting for my age) and weight about 11 1/2 stone. I'm 5"6 and am a UK size 12. I am 'chubby'.
I have really low self esteem and am sick of being this way.
I want to loose about 2 stone (if possible more) as soon as possible.
My ideal weight would be just under 9 stone.
My parents have an excercise machine (cross trainer thing/ skiiing/ treadmillish?).
I ran 10 miles on that every day for a week a few months back before getting sick and quitting.
I need lost of help guys, please don't tell me about health risks and putting the weight back on and how i'm too young.
Trust me i know exactly what i'm doing.
I plan to drink alot more waterr also.
How much should i exersize daily?
How many calories should i try to take in?
JUST GENERAL HELP PLEASE?
p.s. i eat just as much and the same quantities as all my friends who are skinny, i also excersise the same. its really unfairrr.

Well first of all dont compare yourself to your friends that are skinny and stuff because youre all different and your body works different...I know it sucks!I mean my two best friends they eat like PIGS like chocolate sweets junk food soda everything like every hour but they are sooooooooo skinny!And i even eat less than them and what I'm like 40 pounds heavier ! Anyway [I'm 13 years old too so dont say nothin =P] I dont think exercising DAILY is healthy for some reason..i think youre working your body too hard and since youre pushing it too hard its going on survival mode meaning its saving as much fat as possible for energy...isnt that fucked up or what?lol anyway i recommened probably 3-4 times a week of exercising and it should really help using variety for exercises...for me its usually swimming cuz i love it n you dont sweat and its the same exercise as biking and jogging i guess...plus its fun.. and it shouldnt really matter how much calories youre gonna eat cuz since youre exercising so youre using the food as an energy source...and i think being a girl helps to the fact that its harder for us to lose weight [!!!!!!well doesnt that suck]especially in the thigh area[!!!!!! sucks even more]...anyway from the ideal body weight calculator it says youre just in the risk of becoming overweight so you shouldnt be worried too much at least youre not obese

"A 13 year old (female) child who is 160 pounds and is 5 feet and 6 inches tall has a body mass index of 25.9, which is at the 94th percentile, and would indicate that youre at risk of becoming overweight."

So maybe the fat in your body is just distibuted differently than youre friends so it may seem like youre ""chubby" or what not.I mean some people gain fat in their boobs their butt their thighs their belly their arms anywhere!


Anyway I just want to emphasize that you shouldnt compare yourself to your friends ok? Because everyone's body works different and plus youre a teenager...your body acts weird around these ages so maybe wen ur older your just gonna shed all those extra pounds...and dont starve yourself cuz thats just slow suicide...and if you have a low self esteem then talk to your parents or your mom or someone to talk about how youre feeling about this and its also great for someone there to be with you...and if you think you cud take the time n ask youre friends how they do it then mite as well...but if theyre wrong dont try it...geee i sound old..lol..i realllllllyyyy should take my own advices...but oh well...good luck!

Oh and I think exercising too much is the reason why your getting sick...so dont try and kill yourself with this cuz just remember that looks arent everything and its the inside that counts...but in this industry its the pressure of being thin is whats causing all these messed up lives so i understand where youre going at....[Damn i sound old!lol] Oh well I hope this helps..
