How much weight can you lose in two weeks if you run two and a half miles everyday and eat healthy?

You burn approximately 100 calories for every mile you walk. For every 3500 calories you burn you can lose approximately one pound. So every five days that you walk 7 miles you should lose one pound.

Weight gain and loss is based on both diet and exercise. If your caloric intake is greater than the amount you burn during the day, you will gain weight. So this needs to be taken into account as well.
