So, what's right and wrong? *braces himself for PHers to say completely opposite things to each other*

[didelydoo]

They are ALL wrong. I know the answer but it's proprietary information.....possibly...

I'll just continue doing what I'm doing, then!

Probably the best approach to take!

If it works, don't change it.

The first 5 seem to at least quote some decent sources (journals and the like). I'd be wary of anything that makes bold claims but has no research to back it up.

[mattikake]

Any chance of paraphrasing? The first link talks about diet and the last one about HIIT?

I've scan-read the first 2 while watching the BBC F1 replay and the 2nd article seems to be based around some person-specific figures using calorie rates I'm not familiar with and I lost interest in the other 2, so I say the last one is (most) correct. HIIT definitely has it's benefits in inducing stressor hormone production, which consequently force hormesis and recovery processes, which are certainly *a* means of increasing metabolism.

Actually the guy talking in the 2nd article seemed to be a bit of a donkey, but whatever.

We're all different, some things work better for others. If you're making progress doing what you're currently doing and you're happy....why change it?

Well, I really wanted to provide good reasons to someone for adopting more HIIT as part of their training.

He was talking nonsense, then?

Wow. This takes me back to the 1990s.

Partly and something in the way he's regurgitating something from a Dr. that he seemingly had a drink with in a bar, that creates a chinese whispers kinda ring to the whole article.

And also - Fat storage burning 2 calories per hour is news to me. I've been scouting around looking for a metabolic process involved in fat storage that costs energy. That's whilst fat is stored, not in conversion like lipolysis or in lipid conversion or transportation like those involved in VLDLs, LDLs, etc. Not saying that it doesn't happen, but I've not been taught it, or even had the slightest hint that it exists. Kinda defeats the purpose of fat as an energy store if it costs energy to store it, yet also being well-aware that many biological processess are not perfect or long-winded energy return systems like gluconeogenesis for e.g.

Then also that his maths were base on someone that had 50lbs of fat replaced with 20lbs of muscle for the system not to be worth it. Well we don't all have 50lbs of fat to start with...

Then I lost interest in what he had to say, like you would a donkey.

ph btw, HIIT. Do it, include it. It's not only a faster way of burning off glycogen but it's also fun and over quicker. I get nothing but positives from doing HIIT with people.

when i first got in to training i cut my calories increased protein. Common mistake. as you do slow your metabolism down (as well as have less energy.)

I now eat 2800-3000 calories a day and have lost way more body fat. (lean meats, whole grains, completely avoid bread although eat things like trail mix/fruit to give me instant energy)

Bodybuilding combined with interval training (I do boxing with fitness circuits) is the best way to lose fat, gain muscle (if you want to look fit and not be like arnie).

You do get an "after burn effect" where your body burns calories the next day 2-400 more depending on exercise. This is achieved by interval and weight training.

If you just do cardio then you burn what you burn while doing cardio, so interval training is more efficient especially if you don't have time to run for hours every day.

A great source of information is www.scoobysworkshop.com

To be fair, if a donkey started talking to me I would be very focused.

My experiences of HIIT have been very positive. I've had acquaintances also take up HIIT based on what I've told them and had great results. Just that some people need to see scientific evidence.

This has been my experience.

Reet, so prior to going on holiady I nailed all kinds of weights and cardio and ate very lean - and I got the results I was going for.

Now I'm looking to bulk but not put on too much fat (isnt everyone ; )

So, I'm eating more - lifting heavier. But I'm keeping the cardio up because, well because I enjoy it!

But will eating more, while keeping the cardio up actually increase my metabolism?

I suppose my question is, can you really actually speed it up? Or is it bks? Happy to accept it's bks - I've long suspected it anyways.

[Halb]

You can increase you basic metabolic rate with a larger mass.

I think this bit is the issue. If you hadn't done cardio and then started doing it, your metabolism would increase. The way you can increase metabolism now is by doing HIIT rather than steady state cardio. According to some! Well, it worked for me.

It's not news. It's been known for... ages (at least 5 years, and probably a couple of decades) that increasing intensity of CV is far more effective than increasing duration in terms of post exercise fat loss, calorie usage and a sustained higher metabolic rate. The bonus of low intensity CV is that it's easier to do. HIIT just gets you into this higher metabolic zone more quickly and keeps you there for longer when you've finished the exercise.

Although I don't know the maths or any direct scientific study, but I wouldn't expect 5 mins of HIIT + 55 mins of raised metabolism to be anywhere near as effective as 60 mins of low intensity CV for total calorie burn. ATEOTD there is no magic in biology.

As for eating more directly affecting your metabolism, in short, I say no. There will be individual genetic differences on how you deal with excess food. There will also be a requirement of matching you calorie intake with what you need for recovery and repair, which will affect metabolism. And also there is calorie expendature involved in digestion, but that can only be so much - constantly digesting - which you should largely be doing anyway if you're eating regularly and properly.

^ all IMO
