500
A pound of human fat contains 3,500 kcals of energy. I born about 60 kcals for every 1,000 metres I row using a gym rowing machine. So all things being equal you would need to row nearly 60,000 metres to burn the amount of energy you will find in a pound of fat. Get to the gym.
To lose two pounds a week, as long as 4200 kcals are what Joe actually needs to simply maintain his current weight; Joe would need to lower his kcal intake to 3,200 kcals (7,000 kcals less per week = ~ 2 pounds of fat a week.)However, it is likely that it would be better for Joe to exercise for 30 minutes each day burning roughly 200 kcals a day, and reduce his intake by only 800 kcals per day to 3,400 kcals. Anyway... there are a number of different approaches to reach the goal, but diet and exercise should be used.Also, 4,200 kcals seems higher than most men would need to simply maintain weight unless Joe is already burning the extra kcals due to exercise.Good luck Joe.
A pound of fat is generally around 3500 calories, so to lose a pound of fat a week you would need to lose 500 calories a day
The same way as anyone else: you have to create an energy deficit (kcals in < kcals out).
If you are an average sized man, doing an average amount of exercise you could lose up to one pound in a day- that would be if your body did not go into starvation mode and your metabolism did not slow down Obviously the smaller you are, if you are a woman, and if you do less exercise you will lose less
If you eat less, your body will lose fat first. If you continue to eat less, your body will eventually burn all of the fat and then will begin to burn muscle. Yes, you will eventually lose muscle.
There are 3500 calories in one pound. Cutting 500 calories a day would make you lose one pound each week.
You might want to rephrase your question, but to lose one pound, you must lose one pound. Every 3500 calories is one pound.

1 pound equals 3,500 calories. You can burn around 0.1 calories per jump. 3,500 calories divided by 0.1 calories per jump is 35,000 jumps in 1 pound. That would take almost 3 hours to burn off (at 200 jumps per minute)
It take about 3500 calories to burn 1 pound of fat. So that would mean that if you lower you caloric intake by 500 calories in a week you would lose about 1 pound.
