if i have a calorie deficit of about 500-700 per day, how many miles a week should i be aiming to run to optimize weight loss?

sounds like a big deficit already. How fast are you planning on dropping weight? Do you care about retaining muscle or not?

The amount of calories it burns depends on how quickly you're running and for how long, not exact distance covered.

^ Yes, but you can use 100 cal/mile to guesstimate things.

I just remembered I had bookmarked this RW article which says, basically, it's 0.75 x your weight in lbs per mile.

running is really a terrible way to lose weight... I'd say if you can find somewhere to swim and ride a bike, that'd be a better option. No impact, plus they burn a lot more calories and build muscle (which burns fat).

Actually, interestingly enough, running speed has very little influence on calories burned. It is almost solely a matter of distance covered. That said, I'm not sure how to calculate your calories/mile. It depends on your running form and mechanics as much as on your weight.

Distance = Speed X Time

So a guy who runs 10 miles in an hour burns the same amount of calories as the guy who runs 10 miles in 4 hours?

Assuming everything else is identical(body weight, course incline etc.), yes.



Of course you can reason there's no chance in hell the 1st guy would burn 0 calories in the 3 hours he's NOT running. Then again, that would be cheating.

You need ~7,500 more posts to reach that next level. Till then,

No. What I said is approximately true, in most real world situations. Velocity does effect the number of calories burned. But, for the most part, the differences in velocity are not great enough to be significant. It is pretty much unthinkable that a guy capable of running 10 miles in one hour would ever run it in four hours. Even two hours would be ridiculously slow. In fact, the difference between a hard ten miler and an easy ten miler is probably only about twenty or thirty minutes. Within that range of paces, calories/mile will be practically constant.

If you think of human body as a simple machine then yes...the physics work out. But if you want to be 100% accurate, you also have to factor in physiological factors like breathing rate and heart rate to calculate exact calories burned. You defintly burn more calories sprinting then jogging or walking a mile because sprinting increases your breathing rate. You metabolize more O2 which means more energy spent.

Ah, there's some physiological psychobabble for sure.
