1kg of fat contains 7700 calories.
If you use a stair machine for 1 hour and you weigh 90kg, you will burn 800 Calories.
So about 9.5 hours of work on a stair master to burn 1kg of fat.
Note: Your body converts the fat to sugar to use but it only does that when your sugar has been low for long enough (at leat 4 days), that your body chemisty has changed to convert fat.
Never try to do this all at once. Sudden sugar loss is dangerous. Too much exercise too suddenly is dangerous.
