caloric fluxYes folks, stupid me completely misrepresented caloric flux in the last post.

But, kind and wise gent that he is, Ari emailed me and straightened me out within a few hours of posting it. Instead of posting his response in a comment or changing the article, we figured it made the most sense to post it prominently here for everyone to see.

By the way, Ari’s book Forever Fat Loss, one of the bestselling eBooks on the subject since it was published 10 months ago, is just 99 cents again for today, April 4. If you haven’t read it, you should unless you are in the midst of recovering from an eating disorder.

Here’s Ari’s clarification on the concept of caloric flux…

Hey Matt,

Just read your article.
To clarify, there is no such thing as a “state of caloric flux.”
Caloric flux is simply the term for how many calories are going in and how many are going out.
  • A person consuming 1,500 calories per day and burning 1,500 calories = low caloric flux
  • A person consuming 4,000 calories per day and burning 4,000 calories = high caloric flux.
But again, there is no “state of caloric flux“. High flux or low flux is simply a way of determining whether someone is regulating energy balance at a higher or lower baseline of calories in, calories out.
As far as what you wrote here: “‘caloric flux,’ which basically means to lose weight by increasing your physical activity without a reduction in calorie consumption.” 
 
This is also not correct. Caloric flux doesn’t necessarily say anything about weight loss. It is not the same as a caloric deficit.
 
But you can talk about differential effects of creating say a 500 calorie deficit at a low caloric flux (consuming 1,200 calories and burning 1,700 cal) vs. high caloric flux (consuming 3,500 calories and burning 4,000) and how the same caloric deficit at different caloric flux levels impacts, for example, metabolic markers, or overall fat lost, or subjective energy levels and mood, etc.
 
Moreover, the recommendation for a person to consume more calories (based on overfeeding studies that show that overfeeding promotes increased calorie expenditure via increased RMR and NEAT) is a method of increasing caloric flux.
Increasing caloric flux simply means going from regulating energy balance at a low calories in, calories out TO a higher calories in, calories out.
It says nothing about HOW you accomplish that… i.e. whether your method of going about increasing caloric flux is simply exercise (a la Berardi), increased caloric intake (you), or gentle movement/NEAT.
Different ways of increasing caloric flux have very different effects in terms of how they affect us (RMR, energy levels, stress, fatigue) and ultimately, in terms of whether they are sustainable strategies or not.
Increasing caloric flux by doing two hours of p90x each day vs. by doing ample gentle movement vs. by overfeeding… all of these will have very different end effects. But they all technically “work” to increase caloric flux.
