Well, since 1 pound equals about 3500 calories then it well take 3500 calories to burn it off, but DO NOT try to burn it all off in one day. You can become ill and possibly die from it.
Rule-of-thumb says that a deficiency of 3,500 calories will lose you one lb of fat.
3,500 calories = 1 pound of body fat
A 150 lb person would burn 429 calories in 1 hour of moderate downhill skiing.
It depends on how many calories you eat versus how many calories you burn through this exercise.
When I was this weight I used to burn about 600 calories an hour, This is of course dependant on how hard you work. Technically the hifger the level and the faster you go,m the more calories you will burn. I was doing level 6 at 50-60rpm and was burning 600 calories per hour. Hope that helps
