I am 67 kg and my height is 5'4". how many kilometers do i have to run to loose my weight and bring down to 62 kg?

770 Km.: As a rough estimate, running burns about 600 cal/hr . With 3600 calories/lb of fat, we are talking about 6 hours of running to lose 1 lb. Ten lbs is about 60 hours of exercise. Assuming that diet remains stable. How far can you run in 60 hours? At 8 mph ( a respectable speed) you will need to go about 480 miles ( about 770 km ). Fat is a very efficient fuel. Better not to eat.

Burn 38,500 calories: There isn't a set 'distance' you can run, but roughly everytime you spend 3500 calories more than you take in, you will lose one pound...There are other factors (state of hydration) which make weight change with exercise...To lose 5 kg (about 11 pounds), you need to create a deficit of about 38, 500 calories...500 calorie daily deficit = 1 pound per week..To lose 11 pounds..About 11 weeks.
