That depends. If He is lazy and sits at the computer all day or watches tv all day or can't physically exercise then not many. If he plays Basketball or runs then he may burn a lot. You need to burn about as many as you take in or else you are going to gain weight (fat). Hopefully if he takes in 2500 calories of food then he will burn around 2500 calories.
Basal metabolism rate=1,3 x {66,4 + [(13,7 x weight(kg)) + ( 5 x height(cm)) - (6,7x age(years))]}
(for a man)
This represents the amount of energy burnt considering absolutely no physical activity (even get up from bed), but is very far from the real value for a average man with normal daily life activity
One must burn 3500 calories more than s/he consumes to lose one pound. Losing more than 1-2 pounds a week is unlikely to result in long term results. It is best to try to reduce calories by about 500 calories a day (either by eating less, burning more or a combination). At this rate, by the end of one week you will have lost one pound.
Moderately active people need to eat about 10-15 calories for every pound they weigh to stay weight neutral. Therefore a 100 pound person should eat about 1500 calories a day; those with a slower metabolism may need to eat less.
Yes. Because the main purpose for you is to burn calories in order to lose weight.
Not really. Only athletes should burn excessively high amounts of calories daily.
Consume less calories than you burn.
It depends on your height and weight. 2000 calories is probably close to your daily need though.
several thousand- Over 9,000 at least
If you mean how many calories you should eat, probably between 1500 and 2000 calories depending on your sex and activity level. There is no set number of calories you should burn every day; the calories you burn should be high enough to reflect a healthy level of exercise, but not be excessive such that you lose too much weight over time.
To maintain your weight... eat as many calories as you burn. Most humans, without even excercising, burn 1500-2000 calories a day just doing daily things and...surprise, surprise, living! If you are trying to lose weight, you have to eat a significant less amount of calories than you are planning to burn in a day. So, if you plan to go on a 3 mile run, and burn a total of 2300 calories in one day, to lose weight you have to eat less than 2300 calories. AND gaining weight is just the opposite...eat more calories than you burn.
It takes 3500 calories to lose a pound
3,500 calories.
depending on your weight you will burn more or less calories, but a male weighing about 150pounds should burn around 600-800 calories.
alot... alot...
same amount you burn.
