I'm a seventeen year old school girl from Hong Kong, trying to lose weight, stay healthy and ace my exams by July.  I'm often told that I'm at a healthy weight for my age and height, but it's pretty hard to think that way when the average Chinese girl over here weighs below 100 pounds and looks like she'd float away in the breeze any moment. 

Usually I exercise a moderate amount - jogging for 30 minutes twice a week, gym for 1.5 hours thrice - but have recently become a hermit due to the need for more revision time. 

My goal is to get to 110 by the end of May.
