I need some good weight loss tips and and pro ana sites.?

Well I just really need to lose weight 'cause I'm an over weight 14 year old. I just wanna slim down a bit. I'm not planing to go anorexic I still want to have the energy to horse ride because I love my horsey (: I need to slim down everywhere mainly tummy and muffin tops and thighs . I want the pro ana sites for inspiration, thinking one day I can be skinny... Don't say all the 5 a day 3 meal things I already do but in the last 3 years I've lost nothing! Thanks
