im gonna have ALOT of time this summer to run, there is this canal that is like 2.5 miles long which im planning on running it 3 times a day.

let say for example i eat 150 calories before every run , and after im done running lets say i burn 250 calories, from those extra 100 calories that i burned will it be fat?

Generally, for the first half hour of cardio, the energy you burn is from your stored glycogen levels, which means that it's basically from your body's "quick supply" of calories taken in from your food.

After this barrier has been crossed, everything you burn is purely fat.

But you still burn fat before it... just slower. Plus, cardio gives your metabolism a kick which'll also burn more fat throughout the day.

But for max results, yeah, train on an empty stomach. Pre-breakfast cardio is the SHIT for leaning up.

WRONG.

Goddamn. And the OP pic irks me. Human physiology isn't so woefully simple.

Don't do fasted cardio.

lifting gives a bigger kick to your metabolism than cardio

Ok, so there is more to it than that, but who cares! Running will lean you out, running on an empty stomach even more so.

It's not the amount of time that you run, per se, but the intensity at which you run.

At higher intensity, your body will use glycogen almost exlusively, because the metabolic pathway to turning it into energy is faster. At lower intensity your body will use fat. The ideal intensity for using fat for energy is 65-80% VO2Max. One of many sources for this statement: http://www.cyclingnews.com/fitness/?id=letters2002_11_07


Since it will be asked: The reason why HIIT works is NOT that you're burning fat while engaging in intervals. The point of HIIT is to raise your overall basal metabolic rate; if your BMR is higher, you'll burn more calories while at rest (sleeping, watching TV, etc).

would High Intensity Interval Training be less effective when doing it right before you sleep?

What is it with you people overdoing your cardio? Start small. ._.

7.5miles a day isn't actually very much unless he's going from nothing. Although I'd give yourself atleast 2 days off a week to let your muscles recover, more so if you're new to running.

If you are new then stage it up or you may well end up doing damage to your leg muscles (running is a pretty stressful sport for your skeletal/muscular structure).

Also the opinions on how to burn fat vary.
There's a few things that are agreed on, but most all of them apply to both high/low intensity interval training and medium intensity long duration fat burn training, and that's that the exercise will increase your metabolism.

If you are looking to lose fat (not weight), then I'd recommend putting some of the time into resistance training (even if you're female). Obviously if you are female then use lower weights for higher rep amounts (aim for say 20-30 reps) getting a bit more muscle on you will speed up your metabolism a lot.

Put a bit of focus on what it is you eat aswell, not just the calories, eat good proteins (eggs, lean meats and nuts etc~) for muscle repair and decent carbs

Fucking idiots, yes, constant long boring slow paced runs will help you "lean up" but you lose a GIANT amount of muscle along with the fat and glycogen that you burn. Then, as soon as you stop running as much, with less muscle in your body to burn calories at a base rate, you BLOW UP INTO FREE WILLY.

THIS is why HIIT is a much better solution. And it's alot harder to get bored with HIIT when you can get an AWESOME session in at 20 minutes tops.

You cant blame the skeptics though. When someone tells you that you can increase your metabolism all day and burn fat without losing muscle in just 20 mins rather than hour long cardio sessions, realistically how does it sound?

Okay, I can admit that if you don't understand the logistics of it, it can sound fishy. But what do you think burns more fuel: a drag-racer in 2 minutes or your honda civic in 6? I have to find the article that actually explains the difference betwixt cardio and aerobic, anyone have?

Yes, exactly that one. Although, (and I know, it's hard for me to believe too), some people actually just want to be skinny, and not strong. Weird.

HAHAHA this "aerobic fallacy" is so full of shit:
"Let’s examine the chicken and the duck. The duck can fly for thousands of miles while the chicken can’t even get off the ground for more than a few seconds. " Chicken's can't fly because their wings are fucking vestigal. NOTHING to do with how much cardio a duck does or how many SQUATTZZZ the chicken does. If you get up off your ass and move around a lot, you're going to burn calories. end of fucking story.

When you're fat you would rather just lose weight as fast as possible, problem is you end up losing alot of muscle so at the end of the day if you're going to do it, might aswell do it right.
