Since you don't use as much energy to get around in a weightless environment I would say you would need fewer calories.
Yes. If you consume more calories than you need one day, you will "store" them. If you consume less, you use any "stored" calories.
According to the weight of the body we need to decide how much calories must be taken in.
more
Cuz they is fat
It depends on how fast you want to lose those 15 pounds by. To lose one solid pound of body weight, you need to burn 3,500 more calories than you consume. For 15 pounds, that means you need to burn 52,500 more calories than you consume. Here is the breakdown of the time it would take and the calories that would need to be cut out.... (this is also assuming that you are exercising and burning a considerable number of calories, daily, too.) * 1 month = 1750 calories less daily. * 2 months = 875 calories less daily. * 3 months = 580 calories less daily. * 6 months = 290 calories less daily. * 1 year = 145 calories less daily.
It depends on how active you are and how old you are. Daily recommendation is 2000 but you need less if you are less active and more if you are more active.
for more space you need less homes, buildings,more land etc (this answer is if you want more space because i dont know what you mean by space or outerspace?
Some people need more calories than others due to the amount of physical exercise that they do. The more exercise someone does, the more calories they will need, as they burn them off much faster than someone who does very little exercise.E.g A 21 year old woman who has a job working in a office will need less calories than A 21 year old woman who is a fitness coach or a P.E teacher as they are constantly exercising and burning the calories off quicker.Men also need more calories than women.I hope this helps !! :)
Actually no, they need more. Kids should take in between 1,000-1,500 calories a day, depending on their age, weight and height. Adults, on the other hand, should consume about 2,000 a day, generally. It may, however, be more or less, again, depending on the person. Ask your doctor if you want a personal check about how many calories you need.
Food with less fat and less calories.
More likely, it is growing teen males who need the most calories.
It depends on how many calories they consume; if you are of a slighter build and eat less calories, you need to burn less.
