A healthy teenage diet?

I need to lose weight by july, [maybe even may if possible for my graduation]
I want to lose at least 20 pounds by then. I weigh around 140 right now and would like to be how I was last year.

I want an heathy way to do it too, no drugs, no starvation nothing.

Currently I don't drink soft drinks, I don't eat much candy, but I do work at nights and I cannot eat a well balanced dinner.

Help please??

Thanks<3

you need to change your eating habits for life if you want to stay trim for that long! just don't eat saturated fats. (nothing fried)

I lost 105 pounds in 6 months. Here is how I did it.
1. Every morning get up and walk for 45 minutes. You can start with less time, but you want to get up to 45 minutes, and it must be fast walk. You want your heart rate to go up. It must be in the morning, it kick starts your metabolism.
2. I cut out Red Meat, and fatty foods. Boneless skinnless chicken breast, baked, or grilled, rice and vegetables (steamed).
3. Eat half. Just eat half of what you normally eat. Put 1/2 on your plate, and put the rest away. Cook less. When you go to fast food, get salads only. Or grilled chicken. No fries, only diet soda. Or water.

It will work, once you get into a routine, you will get hooked on the results, and you will keep the routine. It has been over a year for me.

Also start counting your calories. Write them down. You would be amazed as to how much more aware you are of your caloric intake, if you actually write it down. We recently discovered a site that offers a great program that counts calories, as well as keeps track of everything. It allows multiple users, so everyone in the family can keep track. They offer a free 7 day trial, and so far I am very impressed with the product. Try the 7 days and see. It allows you to add the exercise that you do during the day, which increases the amount of calories you can take in. Very Cool!!

Stay motivated, and get up and walk every day. I seriously lost all my weight starting off my day on my walk.

Good LUCK!
