It is well known that stress is important for fitness. Indeed, in Darwin's framework we evolved because of stress: "Survival of the Fittest".

Others expressing a similiar view are Nietzche - "That which doesn't kill me makes me stronger"

Or Hans Selye and the General Adaptation (to stress) Syndrome.

We know that physical exercise is stressful and done properly results in increased strength following recovery.

We know that the Finnish practice of Sauna and swimming in the Baltic Sea has highly reputed health benefits.

And we know that when an animal (pet) is injured it will often cease eating (suggesting nature's way of recovery).

Below is a great article which ties together three types of stress (diet, exercise, and mental) at the cellular level. The article suggests for me at least the benefits of

- Exercise (like Crossfit)
- Intermittent Fasting
- Intellectual Challenges

work and family safe

Is is worthless to do a 24 hour fast?

What I've read from the performance menu etc intermittent fasting is effective if done overnight to lunch or lunch to breakfast, I have been doing this for quite a while and have seen positive results, many of my PR's have fallen on IF days. Like CrossFit, not a whole lot of research on the topic. I'm sure there are many more qualified people to answer your question though, i'm listing personal results only.

weekly, only one or two days though, I do it on purpose and not by mistake. I really believe it has helped, havent been sick through this time either. On a whole I also eat pretty clean 90% of the time anyway and intend to watch even closer to start the year.

Alfonso,

I posted this link under Fitness because it referred to stress under the catagories of Fasting, Exercise, and Mental Challenge.

For specific info on the fasting look under Nutrition on this board. There are many outstanding contributions there. Some are very recent.

You might also search for Robb Wolf - he has written extensively on the subject.

Personally I think that relatively short-term fasts are doable (not too stressful) and show great promise. If I had cancer I would consider longer fasts - say 4 days (based on a Robb Wolf interview).

Also check out Art Devany - he has a lot of interesting ideas - most notably using randomness in the process (sort of like the WOD)
