Emilio > Can you still afford an active lifestyle with this levels of  
calories? Me, I could barely shift from the couch to bed and  
viceversa... which makes me think I'm not a very efficient machine.  I  
don't know for sure, but I suspect I'm on a 2.500 calories per day  
regimen and I don't loose nor gain weight so for my build and  
lifestyle should be ok.  What's your weight and height, if I may ask?

I am 5'9 and 170 pounds.  My ideal weight is 155-ish.   Let me tell  
you about my activity levels.  I believe there is some very strong  
evidence that hunter gatherer men followed what we'd call a high  
intensity workout model.  Very intense effort every few days followed  
by mostly lazing around doing nothing,  So that's what I do: I work  
out twice a week at high intensity.  Don't scoff.  I have no problem  
jumping up and running a half marathon with little training -- or  
doing a sprint triathlon.  The goal of exercise for most people is a)  
weight loss; and b)muscular toning or size.  But if only an hour of  
work a day -- combined with a paleo diet gets you there -- why in  
hades would anyone spend the hours upon hours at a gym or out on a  
trail?  That slogging away is such an enormous waste of time and  
energy, IMO.  And the injuries...

Sorry for the tangent.  Bottom line is I don't get fatigued -- as long  
as I'm getting enough electrolyes in the form of salt, magnesium and  
potassium.
