I really need advicee! pleasee!

People are talking about age here; it's the HEIGHT that matters. >_>

Some things that could help 你 out here:
1.) Take frequent walks, usually up to a half an 小时 或者 more. 你 can always build up the 分钟 日 由 day.
2.) Eat 更多 frequently, but in smaller portions.
3.) Let someone make your plate for you. What 你 have on your plate is what 你 get; no need to go for seconds.
4.) Eat foods that are high in water, such as tomatoes, cucumbers, etc. Other foods such as cabbage can fill 你 up too, but won't add a pound.
5.) How 你 feel about yourself is also a big factor, but not a lot of people see it that way. Stay confident and happy, and no matter what your weight is, be satisfied with who 你 are. Nothing should change the way of how 你 view yourself.
6.) If 你 don't want to do it alone, 你 don't have to. Ask some 老友记 to help 你 out; often doing things with someone will take your mind off of it, and then it'll seem much 更多 fun (and less like something 你 HAVE to do).
7.) Really really really important: DRINK A LOT OF WATER. Water is always good for the body, but 你 don't have to follow the "eight cups a day" rule. Who 说 你 had to do that? Forget about it and just drink as much water as 你 want. If 你 just want a cup 或者 two a day, then go ahead. At least have one, and that's all that I'd suggest -- and ask for.
8.) 你 could try exercising, but there's a difference between that and dieting: exercising = building muscle and losing some fat, but dieting = losing 更多 weight than that of working out.

Hope this helps.

Why would 你 want to loose weight? 你 sound perfectly healthy and skinny to me. I weigh 116, and i'm the skinniest out of all of my friends.

But, if 你 really want to, just tell your mom that 你 want to have a 更多 healthy variety of 食物 and to go on walks 或者 something similar.

okay.. 你 obviously have a problem here
you're 13 i am not good with pounds(as i use kg) but i know that i am about 119(which is like 54kg) and i am 17. So for a 13 年 old that's a pretty good weight, seriously 你 don't want to be a stick. I know 你 will probably say 'how would 你 know' 或者 something like that because i have always wanted to be thinner.
But anyways if 你 realy want to then i suggest exercising..(a lot) and cutting down on unhealthly foods(once is okay..but all the time is not good)

Do not be embarrased, tell your mom she'll handle it and just cut out frm eating sugar and foods that gives a lot of carbohydrate before going to bed.

U have to face ur fears and ask ur mum for advice:)

ALWAYS eat in the morning!!! ALWAYS if 你 don't eat breakfast when 你 come 首页 from school, 你 will eat 更多 than what your supposed to. And, when 你 eat breakfast don't just eat a gronalo bar eat ceral, and about the serving size on the box. Don't stuff yourself at lunch, and in the afternoon if 你 still are hungry after 晚餐 don't get 秒 get a fruit, 或者 something small 你 love. AND NEVER STRAVE YOURSELF!
