Someone please help me lose weight?

I'm not fat nor I have I ever been, I am just a 14 year old boy, but my uncle used to be a quite portly man and now he is buff and fit. I highly suggest getting a gym membership and maybe even a personal trainer, then you feel obliged to go workout. Just buying a treadmill might give you the comfort of thinking "I have some way to lose weight", but if you are actually paying for a gym membership an a trainer then you feel like you have to workout. Also, try to eat a little better, get rid of the junk food in your pantry (except maybe ONE favorite) and replace it with similiar, healthier alternatives. Also, you can buy a healthy cooking cookbook and learn how to make meals that are tasty yet low-cal. You can do it, don't give up! Plus once you lost that weight I recommend P90X to get you in peak physical condition. It will kick your butt but the results are amazing. Don't give up. It's a war between you and yourself so your know your weaknesses, destroy them.
