Adding physical activity to your daily routine can help you shed unwanted pounds. Exactly how much weight you lose will depend on just how much activity you add. While a half mile of running won't yield quick weight loss, it will have an effect in the long term. For more significant results add more physical activity and limit your calorie intake.
A half mile is a relatively short distance to run, so you shouldn't expect a big calorie burn. According to the website Cool Running, a 200-pound person will burn 79 calories running half a mile. A 175-pound person will use less energy, burning just 69 calories per half mile. For a 150-pound person the calorie burn will be about 59 calories.
A single pound of fat is equal to 3,500 calories. Running for half a mile per day will put a dent in this goal, but the results won't be quick. At this rate a 200-pound person would need to run half a mile each day for 44 days to lose just one pound. For a 175-pound person it would take 51 days and a 150-pound person will need 59 days -- nearly two months -- to shed one pound.
If you're looking for a way to burn fat more quickly, you can simply add more exercise to your routine. For instance, if you gradually increase your runs to one mile you can double your calorie burn. Even simple activities like brisk walking, or mowing the lawn with a push mower will increase your calorie burn. According to the Centers for Disease Control and Prevention, you should get at least 150 minutes of moderate-intensity aerobic exercise per week or 75 minutes of vigorous-intensity aerobic exercise.
Exercise alone won't necessarily result in any weight loss. If you burn 79 calories running and then celebrate your achievement with a 300-calorie piece of cake or refuel with a 200-calorie sports drink, you'll actually gain weight over time. To lose weight the total number of calories you burn from exercise combined with the total calories cut from your diet should create a deficit of 500 to 1,000 calories a day. This will result in weight loss of one to two pounds per week.
