Take in 1200-1500 calories per day.  Exercise 30 min. per day.  If you are a male, then you will need more calories though.

It's the age-old technique of eating right and exercising more!  It is safe to lose up to 2 pounds a week.  Each pound you lose is approximately equal to 3500 calories.  \n\nSo to lose 1 pound a week healthily, you'd need to cut back on the calories you take in and burn more than you usually would.  \n\nTo calculate how much you need to eat a day and how much you need to burn to lose that pound, you need to figure out you Basal Metabolic Rate.  You can do all this here:  \n\nhttp://soyouwanna.com/site/syws/loseweight/loseweight.html\n\nSoyouwanna.com gives a lot of tips for basically everything you'd want to do.  Good Luck and don't overdo anything.

Technically, you lose a pound after burning off 3,500 calories. At the rate you are suggesting, you would have burnt 400 more calories a day than you put into your body. You would *technically* lose a pound every 8.75 days. I don't know how much you weigh so I can't tell you how many calories you need to eat/not eat to lose weight. Starving yourself and working out like crazy isn't a healthy way to lose weight because eventually your body will go into "feast or famine" mode and you will stop losing weight to conserve what you do have left. Our bodies are great that way. You can lose a lot of weight at first but it isn't the kind of weight that will stay off (mostly water weight and muscle weight) once you start exercising and eating regularly. You can't starve yourself forever. Eat a healthy, balanced diet and it should fall into place for you.\n\nThe best way to lose weight is to gradually "trick" your body into getting by on less. If you stay with 1,200 calories a day, and you need to eat 2,000 to maintain your current weight, then that is 800 calories that you are burning daily, just by eating less. Add some moderate exercize that burns 300-500 calories a day and you will have burnt about 1,300 calories, just by living and being healthy. You should lose about a pound or two a week on this schedule, doing it sensibly and without starvation.\n\nRemember also that heavy exercise increases muscle mass, and that muscle mass adds poundage to you. That's good. You burn more calories with muscle than you do with fat. I wouldn't get so hung up on the numbers on the scale as I would with how clothes are fitting, what your friends are saying, etc. If you look good to your friends, and you feel okay inside about how you look, then it's a good weight. If you find yourself thinking you're unhealthy even though you're at a healthy weight, I'd seek some professional help.

It depends on your height, weight, age, and sex.  There are several online calculators that ascertain your particular basal metabolic rate, or how many calories YOU burn in a day.  Once you find that out, you can use that number to lose weight by creating a calorie deficit by eating x number less than your bmr and/or burning them off through exercise.\nHere is a link to a metabolic calculator-\nhttp://www.internetfitness.com/calculators/bmr.htm\n3500 calories equals a pound.  Consume 3500 more than you need/burn, you will gain one pound.  Consume/Burn 3500 less than you need, you will lose one pound.  Aim for 500 to 1000 calories less than your bmr to lose 1-2 pounds per week.  Any added exercise can only increase the results, so exercise away.

you need to find how many calories the exercise burn, find your resting metabolic rate, subtract 500 calories from that, 500 calorie reduction cause weight loss of 1 lb, but be sure to take in min of 1200 calories per day for healthy food and protein,  and half you body weight in oz. per day of water, protein is your energy source when exercising if you do not have proper protein intake you body will burn the muscle convert to fat and use that for energy, if you take in protein your body will burn the fat to help process the protein thus leaving you lean and not fluffy.

The easiest way to determine how many calories you can eat and lose weight is by figuiring out how many calories you burn a day.  As long as you burn more than you eat, you'll lose weight.

It depends on what you eat and when the last time you weighed in because to gain a pound  you would need to have eaten 3,500 extra calories in your case you would have need to eat 10,500 extra calories to have gained 3 pounds. One pound equals 3,500 calories. To lose weight, you need to eat 3,500 calories less for each pound you want to lose or increase your physical activity to burn more calories. I hope this helps.

You will probably not lose any weight with that caloric intake and weighing what you do. Why would you want to lose weight? Are you 3' tall? If you really need to lose weight, cut your calories down to about 1200 per day...that will be good for about 2-3 pounds per week loss. And exercise. Without exercise, the weight will come right back when you stop with the reduced calory diet.

Weight and calories are two different things.\n\nFor example, one pound of fat contains 4,081 (kilo) calories but one pound of sugar contains only 1,814 (kilo) calories.  Compare this to one pound of water which has no calories.\n\nThe calories you burn come from the food that you eat - if you eat one pound of food and perform enough exercise to burn off the calories in that one pound of food you will have neither gained or lost weight.\n\nTo look at it another way, you would need to be engaged in about 2 to 3 hours of intense physical exercise or about 6 to 10 hours of moderate exercise to loose one pound - that's assuming that you don't compensate for the energy used by over eating.

Walking even a hour day will only burn about 250 calories and since you are already weighing 115, you probable need around 1800 calories/day just to function (depends also on your activity level outside of walking). That being so, you would only be burning about 500 calories/day with the eating and exercise combo which means you would lose 1 pound per week. You need to burn an extra 3500 calories for each pound you want to lose but no more than 2-3 pounds per week.  Try to add some harder cardio and weight traning in there to burn calories faster but at your current weight, 1 pound/week is pretty safe.

you need to consume 500calories LESS than what it would take to maintain your boday weight, every day, to lose weight. a Rough estimate for your daily caloric need is 15xbody weight in lbs. For example, if you weigh 150 lbs, you need to consume 2250 calories a day to maintain your body weight per day & you'd need to consume 1750 calories a day to lose weight. Of course, this is a rough estimate & it will defer based on your activity level.

You likely brun about 1850ish calories a day with those stats. Subtracting 500 calories a day from how much you burn a day would equal 1 lbs lost per week or 1000 clories less for 2 lbs. Same goes for gaining weight, adding 500 to however much you burn in a day would make you gain 1 lbs a week.. You should never try to lose more then 2-3 lbs a week.\n\nUm... but since your so small already I think you just try to lose 1 pound per week so you should take in 1350 calories a day... Dont want to starve yourself.
