Wow. This goes against everything I've ever been taught about how to manage your muscles during endurance activities (In my case hiking, cycling, and Nordic skiing), yet, jibes with my experience. And here I thought there was something seriously wrong with me.

What will you do differently after reading this?

Spend more time outside the aerobic zone without worrying that I'm damaging muscle tissue.

An excellent demonstration of how, sometimes, erroneous but entrenched beliefs take decades, generations, to overturn. Next up in the list of stubborn myths people grew up with and find hard to set down: obesity is caused by excessive caloric intake.

So I can eat all the cheeseburgers I want now? Totally ready to start, just give me the thumbs up.

I lost 20 lbs while eating two big macs almost everyday. It just so happened that I was probably burning near 5,000 calories a day when I happened to lose the weight.

You could sit down and eat a jar of sugar if you wanted, you'd just have to be burning that many calories.

Sure you can. But you can't have the buns, fries, or non-diet drink ..

Atkins? Seriously? 5 years later? In theory, sure, we're with you. But in practice, Atkins is a diet for fat people. If you're 250 pounds and you want to get down to 230 and stay there, Atkins is your huckleberry. We all know plenty of fat people who are noticeably less fat thanks to low-carb diets, but I can't think of anybody I know who used to be fat and is now thin because of one. If you're 250 pounds and you wan…

Last time I checked the two weren't mutually exclusive. Going low sugar is good for you. Eating less is good for you and getting off your rear is good for you. One of them isn't the solution at the expense of the other two.

After doing crossfit for a year, I think I knew this semi-consciously but it's interesting to read about it being backed by science. Short, highly intense training sessions lead to very large gains in fitness because most of your training is anaerobic.

I don't see how this is backed by science in this article.

It's strange that you hasn't done this before. Ever done interval training? Maybe your training is recreational in which case the risk of getting injured probably overshadows(?) the gains of intense interval training.

The article briefly mentions interval training as one possible way of increasing mitochondrial mass.

Can you link to any academic papers that dispute that?

a) known fact: insulin spikes cause more calories to be converted to fat, even when the same amounts of calories are consumed b) even diet soda can cause insulin spikes, causing rats and calves to gain more weight on the same # of calories as rats/calves not consuming diet soda There are links off the wikipedia article: http://en.wikipedia.org/wiki/Diet_soda There have also been lots of books written about the insuli…

A calorie is a calorie is a calorie. Because a calorie is a measurement of the potential energy of a quantity of food.

The type of food is what makes a difference. Fatty foods are worse than the same caloric-quantity of fibrous foods (i.e., fruits and veggies).

And there's plenty of research to suggest that food in - food burned by activity (inc. exercise) - undigestable food = food stored as fat.

With a proper diet, you wouldn't be eating the burger to begin with...

Atkins is a diet for people who insist on eating the wrong foods. It attempts to minimize the harm of eating crap without actually encouraging the dieter to eat healthy stuff.

A calorie is a calorie in a beaker in a lab, but not in the human body.

You should read the things I've referenced.

Another crossfit hacker? Wow. (The first place I saw that article linked was from crossfit.com, around the time it first came out. )

I got good results with crossfit (dropped 40 pounds, now I'm "athletic" -- I'd never have imagined I could do 20 pullups before), but I'd do it even if it was only average, because it doesn't bore me.

Running? Unpleasant and boring. Weight lifting? Boring disciplinarian bullcrap ...

Crossfit? I check the website, burst out laughing, grit my teeth, and then do something that seems almost impossible yet takes 30 minutes or less. Awesome.
