Well, honey... What I would recommend you, is a... Ahm, let's say "cliché". This thing of eating healthy and workout, but that's the truth! I'm just like you, 16 years old, and a bit heavier han I should be for my height and age. I started my "healthy life routine" like 3 weeks ago, and I've loose ten pounds from there. If you want to, I'll let you my email to be in contact and help each other in this challenge! Kisses, honey! Don't give up! Airimar.
