You may think this answer is crazy but up to a hundred that is the same with kissing. How ever long you take to eat that is how many calories you lose, so lets say you take up to 20 minutes to finish a huge burger you would lose 20 calories. Here is another example if it takes you ten minutes to finish a salad then you would lose ten calories.
There are about 3,500 calories in a pound. Burn 3,500 calories more than you take in = loose one pound. Take in 3,500 more calories than you burn = gain a pound.
about 195 if you take breaks
In one single smarty there is 5 calories it take 3 minutes on a push bike to burn off one smarty. (5 calories)
In a 16 ounce bottle of soda, there are about 184 calories. The rate at which the sit-ups are performed will determine the amount of calories burned. If 100 sit-ups in around 10 minutes, 57 calories. It would take around 300 sit-ups in 30 minutes.
Assuming you mean how many calories you have to burn a day, it works like this: To lose one pound in a week, you have to burn 500 calories a day more than you take in. Adding exercise will help, even if it's something fun or easy such as dancing, swimming, bike riding, or walking.
If it is a guy of 9 years of age average height and weight and does 30-60 minutes of exersize a day he should take about 1800 calories a day if a girl average height a weight 30-60 minutes of exersize a day then she should take about 1600 calories a day
depends on your bodyweight and muscle mass percentage
3500 calories equal a pound, so if you burn 200 calories a day it will take approximately 18 days to lose a pound, assuming you're burning 200 more calories than you take in.
30 or 40 minutes.
3500 calories
well you don't eat calories to lose weight, you lose them. you have to lose 3,500 calories to lose one pound so i'd say it will take like a year. but if you just eat healthy things with hardly any calories and exercise it will be easier.
