Umm. If you're on a REAL diet, I'd say limit yourself to 1000 cals/day. If you're dieting to lose only a few pounds, try 1500. Of course, it all depends. The national average for which all foods are based on is 2000 cal/day. Kids/teens are recommended to eat even 3000+. I am a teenage male, and I eat no more than 2000. I am not on a diet, but I can function fine on 1500 cal/day, and there's no need for me to pig out. =D But please BE CAREFUL! Don't over-do it. If you stick with your plan for all week, give yourself a treat on Friday. =) That's how a lot of my friends diet. It gives them motivation. Good luck!\n\n***SORRY, I THOUGHT YOU SAID CALORIES, NOT CARBS. AT ANY RATE, CALORIE COUNTING WILL GET YOU FURTHER IN THE LONG RUN.***

immediately cut your calorie intake to no more than 1500 calories per day. eat 3 meals per day each no more than 300 calories per meal and eat 3 snacks per day in between those meals not to exceed 180 calories per snack.  A good way to monitor calorie intake is to pick a food and only eat the serving size of the food.  For example cereal might have 280 calories in it but that is 280 calories in the serving size of 3/4 of a cup so you can eat 3/4 of a cup of cereal.  Dont forget the milk you add alos has calories.  Watch your drinks too, pop and juices have lots of calories. Things high in sugar are loaded with calories.  And one last thing, no eating after 7:30 at night. I used this diet to join the USMC. I lost 20 pounds in about 5-6 weeks.  I also lost another 10 in a week but that was some unhealthy way where I passed out and I am not going to go into further detail about that.  Losing weight quickly is dangerous and the faster you lose it the easier it is to gain it back.  Be wary of diet pills they dont do anything.

It takes 3,500 calories to equal one pound of body weight.  Generally, dieters dump an average of 1,000 calories per day in an effort to lose 2 pounds of body fat per week.  You should never go below 1,200 calories per day without your doctor's approval. If you are in need of losing a lot of weight, you may require more calories, so you'll definitely need to check in with your doctor before proceeding on any diet plan.

You use almost exactly 15 calories per pound per day.  This is a really good estimate for you.\n\nIf you're very very active, maybe almost 20.\n\nIf you're a complete, and I mean complete, couch potato, about 10.

recommending 800-1000 cals a day, could potentially  be very dangerous for some people so, perhaps you shouldn't recommend it?\nhowever, cutting down on your sugar and cals ( to no less than 1400 cals) and increasing your excercise levels is a great idea. well done!

Actually, don't stop eating -- eat more often.  5-6 meals a day, 250-325 calories per meal will keep your metabolism ticking.  Then kick it up a notch with exercise -- cardio to burn the fat, weights to build muscle.

At 15 your body is still developing and growing so it's important to eat the healthiest foods available - and that's not always easy!\n\nWeight goes on easy but comes off slow.  3500 calories equals one pound, so to lose one pound in one week you would need to burn 500 calories each day more than you consume.  Over all, no more than 1-2 pounds loss per week is recommended, and it would be a good idea to consult your physician to discuss a plan.  Walking for 30 minutes a day is also helpful, and for toning try something like pilates or yoga.\n\nFor eating, have healthy snacks ready to go.  A bag of carrots, low fat popcorn, etc.  Maybe it would be good to have sugar free gum or hard candy for those times you just feel like munching.  I also found it helpful to brush my teeth when I want to munch because food tastes awful after that.\n\nIf you cut back too much your body will think it's starving and slow down metabolism - exactly what you don't want.  Make sure to eat enough healthy foods so that your body has the energy it needs to function and then that won't happen.

Doctor's advise against rapid weight loss in children.  It could cause them health problems later on in their teens as well as increase the chances of creating an eating disorder.  Instead, you should limit the calories and increase fruits & vegies, increase exercise and allow their body to adjust.  There is still growing left to do and most people are going to weigh more than 145 lbs. when fully mature.  So, if you just maintain the weight, increase the metabolizm, the weight problem will not be a problem in a few years.

To find out how many calories you should eat a day, you need to calculate your BMR (Basal Metabolic Rate) and AMR (Active Metabolic Rate) which is equal to your Total Energy Requirement.  Here's a tool for a rough estimate.\nhttp://www.preventdisease.com/healthtools/articles/bmr.html\n\nIf you want to gain more muscle you'll have to maintain a daily calorie surplus (above your total energy requirement).  If you want to lose weight you'll have to maintain a daily calorie deficit (below your total energy requirement).  You're already within a healthy weight range so that's great.

If you are active in sports, make sure that you are working hard 4-5 days a week, for at least 30 minutes.  It seems like you do a lot, but some people think that 15 minutes a day is a lot of exercise, and it isn't.\n\nInstead of going on a diet, focus your exercise, and keep a food diary.  Write down everything you eat, and how much.  If you aren't losing any pounds or inches, then start adding up those calories to see whether you really are eating as much as you should.  People don’t always notice how much they eat, their tummy and hips keep track of every extra calorie.  Putting it down in writing helps you stay focused on eating healthier.

a fifteen year old should not worry about his/her weight because at 15, you are still growing.... \ntry to engage in physical activity everyday for half an hour (walk to and from school if you can) and leave some food on your plate at every meal (3 bites is a good starting point)\nMost of all, talk to your doctor and your family so you don't have to go through it alone=)
