Walking vs running

[Lifterforlife]

Fat loss is all about diet. Period. If diet was not key, how do you explain the cardio bunnies at the gym you see every day, doing everything from HIIT to who knows how long duration, and they never change.

It is because it is all about calorie deficit. Cardio should be an extension of your diet, helping to create a higher calorie deficit. If you do not change your diet, cardio will do nothing to making you leaner. More heart efficient/cardiovascularly fit, yes. But leaner, no.

Think about it, if you create a deficit of 300 calories in a day with your diet, or if you "burn" 300 calories with cardio with diet staying the same, does your body know the difference?

Neither, I suggest sprint intervals for maximum fat-burning.

Sprint Intervals Revisited

Can you perform sprints in the manner necessary to burn fat on a treadmill, or must they be done on a track or field? I live in Seattle so the weather isn't always in my favor.

I like walking up the highest incline on the treadmill, easier on the knees and gets the heart rate up there.

If you still really low on your knees and take very long deep strides you can hit your hammie and butt. I love doing that and combining it with running.

Run for a minute: long deep strides for a minute - rinse lather repeat

Your theory is flawed because cardio also speeds up metabolism and nobody knows how many calories can be omitted by having a higher metabolism.

My theory is not flawed...true, cardio speeds up metabolism somewhat, but what do you think happens? The body adapts to it also. It then becomes a non issue.

Just like the fact that was going around about muscle speeding up metabolism, and burning more fat just sitting there, though this is true, it is a miniscule amount, again the body adapts and you simply have a higher set point.

Muscle in fact burns no more than 13 kcal/kg/day. The liver uses much more than that, as well as the brain, heart and kidneys.

"running doesn't burn fat, it defines muscle"


"Walking burns fat, after 30 mins"

Which is true and which is the ultimate fat burner??

I think its all about SIMPLE math, running will burn more calories for the same duration of time. The more calories you burn the larger caloric deficit.

But you're making an assumption that running burns more calories. If you can produce the same heart rate walking quickly, riding a bike, or some other cardio excersize, then your cal/hr spent should be the same.

Or more precisely if you do as much work (physics) walking, like walking at an incline then yes the number of energy out could be the same as running or even greater. I was coming from an assumption that other variables kept equal (such as walking vs runing w/o an incline), running would burn more calories.

Low-Intensity cardio if you want to keep your muscle. Think the Olympians run? Nopers. 135ish bpm thats the going rate

Could not disagree more. The most shredded athletes on the planet are swimmers and sprinters. That is not low-intensity cardio. It is insanely high intensity cardio on short intervals. The people that lose muscle are long distance runners that keep up a medium to high heart rate for hours at a time. Short term super high intensity like sprinting or high intensity for 15-20min is not going to eat your muscle.
