Losing Weight?

Hey,I'm a 12 year old guy %26 I badly want to lose weight because I put some on last month. Its now our summer holidays and I want to come back to school looking comletley different ( weigh wise LOL) its just that I'm not very good at losing it. I was wondering if there are any good ways to lose weight in 2 months time ( thats how long our summer is!) %26 I'm also doing a few TV commericials on Disney Channel and I don't want people to be saying " Hey , that kid is chubby! " when they're watching my TV commericial. Plus, I'm not fat, just a few KG over weight! Thanks,
Answer:
Basically what the first two people said. Cut out the junk food. When you want to snack on something eat some fruit. No soda, at all. Drink only water (yes it is hard but once you start doing it your body actually craves water) Take a walk or jog for at least 20 to 30 minutes 6 days a week. It is hard to break old habits, but once you do you start to reap the benefits. I use to weigh about 195 lbs and now I am at 146, with much more muscle and a lot less fat. I can almost see my 6 pack coming in. Very worth it. Plus you can cheat on your diet once a week, I do.
