Isn't 'fat burning' an urban myth? You have to burn of all the carbs before you get to the fat......?

No, that's dead wrong.

The term you are looking for is HIIT or High Intensity Interval Training. And yes it works.

Sure, you can eat less move more etc but your training will be more effective if you eat the right things and move the right way.

The Tabata protocol?

Isn't 'fat burning' an urban myth?

The fat burning *zone* is an urban myth, unless you're going out for a 6-hour road ride.

If you have a limited amount of time you want to exercise hard to burn as much as you can and lift your metabolism for a few hours afterwards.

Best of all is a short burst of *very* hard (to mobilise reserves into your bloodstream) then hard-but-sustainable for 30-40 mins (to burn what you've released).

Absolutely, but of those two things. It's the diet I'd want to get right first. I know many people that train well, but eat badly and have the bellies to show for it.

Put the cake away first, then get out on the bike.

Before this discussion disintegrates as usual...can we all just agree it helps to eat properly *and* train properly?

As others have said 'fat burning' is a bit of a myth.
You lose fat when you take in less calories than you use.

You can take in less calories by eating less/lower calorific food.
You can use more calories by increasing exercise or increasing your base metabolic rate (the amount of energy you need to just exist) You can do this by increasing muscle as it's a live tissue (unlike fat) that needs energy to exist.

My understanding is that...

Very high intensity exercise causes the body to release hormones to decrease insulin and increase glycogen breakdown from the muscles - to provide glucose - this then triggers the replacement of the glycogen which is quite slow. The high intensity exercise also causes muscle damage which takes energy to repair, and increases muscle strength.

You have to deplete all your glycogen stores before you burn fat - and you'll bonk/hit the wall first.

Not a myth at all. You're ignoring a lot of factors.

Want to be an F1 driver? It's easy, just drive really fast!

Want to be rich? Piece of cake, just spend less than you earn!

Energy comes from several different sources, one of which is lipolysis - the metabolism of fat. Your body prefers getting its energy from fat in fact, but it'll get it from different sources in different circumstances.

You have to deplete all your glycogen stores before you burn fat

That is dead wrong.

They all say the same thing. More fat is burned at higher intensity exercise, but it's less of a percentage of total energy used than at low intensity.

Exercising harder burns more fuel. Fact.
Which, I guess, is what the OP was on about. So you can all crack on now we've cleared that up. 🙂

so you think your "fat" is just inert lipid globules floating around inside you 😆

My understanding is that...

...you really don't know very much about human biochemistry or endocrinology

Slightly more to it than that PP. To be simplistic, you may burn more fat per hour exercising intensely but obviously you can't exercise for as long, so your total workout may end up burning less fat.

But that is an oversimplification and it's a lot more complex than that.

AFAIK HIIT raises your metabolic rate for a few days after exercise which is very effective at burning up fat, and it causes changes in hormones and enzymes (I think.. not sure) which make it easier to burn more fat later.

It also makes you fitter pretty damn quickly, which means you will be able to ride harder and then burn more fat and get fitter which makes you faster still etc.

In fairness many fatties do look quite inert and globular.

I do like these comedy threads, but didn't really expect any to emerge [b]before[/b] Xmas.

We use both fats and carbohydrates to provide energy for movement. How much of each varies in relation to intensity of that movement / the activity being undertaken. And a whole bunch of other stuff.... Its as complicated as you want to make.
🙂

So, get your diet [i]right[/i] and get your fun / sport right. Then you're made.
