So young? What are you doing in sgForums? 
Kidding kidding....
Alright... I feel that at this age, you should consider about your
growth rather than your risk factors, for example having a postive
family history of diabetes. However, having said that, you should
not totally neglect the amount and types of food that you eat. It
is not only important for your growth by taking proper nutrition,
but over-eating them can lead to obesity.
Participate in activities and play sports... if you don't have one,
pick up one or if you feel that you can take it, go for more. At
your age, you should be active and maximize your potential in every
aspects of your life.
Watch what you eat and you should be alright. Reduce all or stop
the junk foods, soda cans, titbits, chocolates or sweets that are
not important for your nutrition, yet it can bring complications
such as dental caries per se.
Btw, I am a Malaysian staying in Malaysia...
