How much do you think I could lose in 2 weeks? Please no lectures on how dangerous it is its my body. I want to go from 140(ugh!! my current weight) to 115. All day at school I eat nothing but some gum. I want to be thin by June 29 MY B-DAY!! so i can go to florida and flaunt in a bikini YAY!! Any tips on what NOT to eat?

The last thing you wanna do is not eat all day, in order to lose weight, you need to maintain a good metabolism. Try starting your day off with a workout and a healthy breakfast. This will get your metabolism going for the day. In order to maintain this, you will need to eat throughout the day. Eat healthy snacks/small meals every 2-4 hours, working around on your schedule, and stop eating around 8-9pm at the latest.
If you continue this daily you will see progress. Don't make the mistake that many girls make and judge success by weight. Someone who weighs 10 pounds more than another person can look a lot better because of their diet and exercise. Quick, unnatural weight loss will leave you with an awkward, skinny-but-out-of-shape looking body. You won't lose weight quickly, but it will balance out better and give you a healthier appearance.

AT 140 POUNDS YOU ARE AT A FINE WEIGHT ( CHECK LINK BELOW ). BUT IF YOU WANT TO LOSE WEIGHT THAT'S GOOD TOO JUST DON'T OVER DO IT.

anyways, good for you on deciding to lose weight. i don't think that you should eat only gum because it slows down your metabolism. meaning that your body holds on to the fat you have in case you don't eat again. i recommend a big breakfast, an average lunch, and a small dinner along with 8 glasses of water every day. excercise is good too but don't overdo it because muscle weighs more than fat. when you drink alot of water you lose alot more weight faster. snacks are good too when you're hungry but don't touch soda or junk food :-)

Don't eat fast food or junk food or food high in calories...
When you don't eat your body will keep what it gets later...lets say you don't eat all day and then eat dinner...most of the dinner you will keep because it needs all those nurtrients..It is better to munch on health stuff all day to keep you full and drink lots of water...
I am on a diet of about 1000 calories a day...Bagel for b/f...soup for lunch...health choice tv dinner for dinner...snacks are fruit yogurt cereal bars...and special k cereal...So far i have lost 6 lbs in about three weeks. But drink lots of water becaue water will make you feel full which will help you not eat...
And get a exercise plan...do thrity min of cardio a day and tonign every other day.

Cut out the pop. Cut out the candy. Cut out un-needed sweets. Dont cut out your meals. Eat a good breakfast, lunch and dinner. As long as you cut out the sweet stuff and exercise you will loose weight.
By cutting out your lunch like you said you are doing, you are just gonna make yourself more hungry during the day-in between breakfast and supper which will give you a bigger urge to "cheat". To grab a candy bar and a pop for energy. You dont want to do that. Eat something for lunch.
If you have access to a doctor get with them, maybe ask a health teacher at your school or a gym coach at school. They can give you better advice.

120 is the perfect weight for your height (5ft=100lbs. + 5lbs. for every inch after)! Try not to sway more than 5lbs. either way. You can starve yourself briefly, like a couple weeks, but it's hard to do and not good for you! Try to stay at 1200 calories per day major good!!! Keep it to proteins, carbs earlier in the day.
