Another Look at Metabolic Damage

Originally I was going to do a full writeup of the recent study making the rounds suggesting that both low- and high-repetition training generate the same muscle growth but I’m going to save that until next week; this topic makes more logical sense given last week’s video on BMI and weighing frequency.  It was also stimulated by a private message I got on FB regarding the topic.

That topic, of course is the idea of metabolic damage, something I have written about on the site previously.  But rather than write something new, I just got permission from Alan Aragon to reproduce an interview I originally did for his (highly recommended) research review.  It’s only $10 a month and chock full (that’s right, CHOCK!) of the most current research on diet and training along with interviews with top current coaches and feature articles on all topics big and small.  Go subscribe, subscribe now.

Ok, so what exactly are we talking about here?  As originally claimed, metabolic damage referred to a phenomenon wherby dieters (typically females) who had been on low calories and performing a large amount of cardio (i.e. typical physique sport contest prep)

  1. Stopped losing fat despite maintained low calories/high activity
  2. Started regaining fat despite those same maintained low calories/high activity

Hence their metabolism was damaged.  I’m mainly bringing this up as the original concept has been somewhat, err let’s be nice and say, “modified” from the original (now being called metabolic adaptation, a concept I’ve been personally writing about for over a decade in pretty much all of my books).

And with that out of the way I reprint my original interview with Alan Aragon (did I mention that you should subscribe to his research review).   Everything in bold is Alan, the other dense walls of texts are me.
