jogging will only make u lose weight, it has nothing to do with your glands. to me u dont look overweight at all. im 14 as well and ive had it since i was about 8 or 9. its a bitch i know. the biggest thing is how it looks through a t shirt. go to a doctor, get your hormone levels checked. thats what im doing on thursday. i dont know if they will give you meds to increase hormones which would probably make ur condition recede. thats what i'm hoping for me. just pop some meds and itll go away. but with my luck, probably not. whatever you do, do not put on weight purposely in hopes of hiding it. it will only make it worse, i know first hand. I'm recovering from that lol.
