How can a 14 year old girl lose weight?

I feel really fat and I always feeling left out meaning that all of friends are skinny and I’m not. I try to do a diet plan but it doesn’t work for me. I don’t know what to do. I’m feeling less confident about myself every day. I want to lose 20...

pounds but how??

Hi I am a 14 year old girl who is like 5'3 5'4 ish and I weigh between 112-115 pounds. I feel really fat, one because my sister is a TWIG and two because all of my friends are really skinny and really pretty. So I am like the odd ball. I want to know how to feel alittle more self confident about my body and self. I try the diet thing and I couldnt stick to it I just love food. So if any of you ladies could help me that would be great.

I recommend you to drink a lot of water thats all you really need.. try to cut down on the soda..and excersise more.. do something fun that you like that involves running..eat fruit when you want a snack dont eat junk...

Ok. Well it sounds like we have a lot of I think I'm fat girls. But don't worry I feel the same way. As my school PE teachers say at the age of 13, 14 and you are active in sports and what not you should weigh 130-135 pounds. Right now I weigh 132lbs. and I feel giant cause my lower abs like stick out cause they're stronger then my upper ones and then my ribs are big so it's kinda off. hmm..truthfully I did this over summer and it didn't make me loose to much weight but it turned flab into muscle.
-STAY AWAY FROM SODA AND CANDY!
-EXERCISE DAILY, go on a run, do crunches and sit ups, push ups TV watchers...etc
-BEFORE EVERY MEAL DRINK A GLASS OF WATER. It fills up your stomatch half way so you only eat as much as your body really needs.
YUP that's pretty much it.

When I excercise I dont feel hungary any more. Also my sister went to the doctors cause she had high cholesterol they told her the max number of saturated fat she could have was 7 in a day. It worked for me too.
