can you please tell me some effective ways to loss weight

Accordng to this Body Mass Index calcualtor http://www.nhlbisupport.com/bmi/ , your BMI is 26.6 which for your height and weight makes you overweight. Your BMI should be around 18.5 to 24.9. I am about the same height as you (5 ft 6 3/4) and I weigh a healty 146(but am 28, not 17). I have about a medium bone structure. Its different for everyone, so do some research, talk to your doc or someone who can help you.
A couple tips I would give you is don't eat past 6pm...night snacking will rack on the pounds, exercise at least 30 minutes everyday if you can...more if you can get in more time. But don't overdo it!!! Drink lots of water, it helps flush you out. Try to avoid eating junk most days, but do take once in a while to treat yourself. When I was dieting I took one day a week(ususally the weekend) where I went out and ate 1 meal of whatever I wanted. It gave me something to look forward to and helped my not go crazy from depriving myself. Make sure you eat enough every day, if you don't eat enough your body will think it starving and hang on to every bit of weight it can.
Good luck! :)

Your about 15 lbs over for your age.Go out and shoot some hoops ,burn off some of that.Lay off bread for the most part and sugar if possible.
