i wouldn't start a "program" if i were you. I'd simply start making better choices.
Its okay to tell your parents that you are interested in "eating healthier" or even just add fruits and veggies to the grocery list (if they aren't already in the house) One of the biggest things is to eat lots of veggies and fruits and also drink lots of water and non-sweetened iced tea, skip the pop and juices. & of course skip the sweets, like desserts and candy.
What kind of physical exercise do you do daily? You do not need to go the gym to burn calories and lose fat. Go for bike rides or walks, & when watching tv, be on your feet, picking up the living room, etc. Good luck to you!

You are only 12 and your weight looks good... Just eat a good diet of everything healthy... no soda, sugery snacks, junk food. get out side and play, walk, run, dance. just keep active. you'll be fine and maintain a healthy weight.
