You are young and a lot of life ahead of you. Get started on your weight right away. Start with little things like drinking water instead of soda pop. Give up a few foods and replace them with a salad. You will be surprised at the results you will get with doing just a few small things. Eventually you will feel like walking 20 minutes every evening. Do it gradual. Try to change your eating habits for life and not just for a awhile.
