Question- I’ve just started my weight loss program. I’m wondering about how to maximize my weight loss. Am I better off running lots of slow miles, or fewer faster miles?
Answer- The simple answer to your question is - running at any speed will improve your over-all level of physical fitness while expending approximately 100 calories per mile.
Running a seven- minute mile will burn a few more calories than running a 10-minute mile because of the added effort. But most people can’t run the extra distance at a faster pace without becoming overly fatigued or injured. So you are likely to run further -and burn more calories-over the course of a week by running at a slower pace.
To lose weight, your energy expenditure (moving and exercising) must exceed your energy intake(eating and drinking). You can do this by eating less and exercising more, or a combination of both. Plenty of slower miles can help create a steady calorie deficit that will lead to weight loss.
