Here you didn't deliver your track length if I assume your track length is 400 meters, 5 laps is equal to 2 kilometers. Assume daily you are doing 2 km run and your weight loss depends upon your running speed, daily calorie intake levels. Sorry to say this, without knowing any of your details it would be hard to tell the answer to you.
Not even 1 pound. Not even close to 1 pound.
do a workout of either running or on any exercise machine everyday until you lose a pound.
That's a bit more than one Pound a day. That's not really doable for ten Days running.
1 Pound
no you cant you can only lose it in days,weeks,or even months.
If you want to lose a pound of fat and not water weight, it takes 3500 calories. So it takes 7 days of having a 500 calorie deficit to lose a pound of fat.
Three days
Don't eat as much.
It is not healthy to lose 10 pounds in 10 days. However, in order to lose a pound a day, you must burn 3,500 calories.
lunges and squats you could try cycling to or running
You have to know that there is NO healthy way to lose weight in that short amount of time. The healthy amount to lose for a week is one pound.
Drinking less water will NOT help you lose weight. You should drink before and after any physical excercise. I estimate you will lose about 1/4 of a pound as 15 minutes of running is not much at all.
