I have stopped losing weight!!!?

I'm 14 years old male 161 pounds,i have recently lost 2 stone and have all of a sudden stopped losing weight, i lift weights eat healthier than the average 14 year old,yet i am 3 stone heavier than most my age I'm very concerned i don't run alot is that the problem or is it genetics,or should i go on a carb diet,i need some advice on what i should do,i know some people say your perfect the way u are but i am always trying to better myself and i can see alot of room for improvement on my body.

at 5'11 youre not very overweight however i would recomend doing more excersise. lifting weigts really isn't enough. do you or your friend have a pool? swimming is an awesome way to burn some calories. if its your stomache, try doing crunches and sit ups every morning and every night untill you see a difference. also, focus on eating tiny, healthy meals every two hours rather than only a few larger meals each day. if this still isn't working for you, you can cut certain foods out of your diet. red meats are extremely fatty so they can go but make sure you eat enough protein and iron to make up for it. also anything white(pasta, rice etc.) contains lots of carbs so try switching to whole grain. Eat more fruit and veggies. most contain negitive calories so you'll actually burn calories just by eating them!! (google negitive calorie foods). but please don't get too carried away. your too young to be worrying about how much you weigh. and please don't starve yourself either-its the WORST possible thing you could do for yourself. Feel good in your skin and good luck!!
