Hi I'm a20 yrs old .if I run 2 kilometres every day so in how many days I can reduce 10 kilos

Assuming you are 170lb in weight and cover a mile in 10 minutes, then you will burn about 128 calories in 10 minutes. So if you run 2 miles a day (not 2 kilometers), then you will burn 256 calories.

If you run 2 miles everyday for 16 days you will burn about 4000 calories, which will reduce your wait by 1 lb. So in 160 days, you should reduce 10 lbs.

This is true only when your daily calories intake is equal to calories burnt. Only then extra exercise will result in reduced weight.

In general, running will not reduce your weight unless you diet as well. When you exercise, you get hungry. You will only lose weight if you can ignore the hunger and not eat anything extra.

Your best bet for losing weight is to watch your diet and try to be more active generally. Rather than running a couple of miles a day, try to walk a lot more. Do more housework, ride your bike, dig your garden, carry shopping.
