La carnitine : miracle ou placebo ?

English version

Carnitine en tant que brûleur de graisse

La carnitine, tout comme la créatine (bien qu’elles aient des fonctions très différentes), est un supplément existant depuis des années (et même des décennies). Elle a toujours été catégorisée comme un produit servant à « brûler » ou « mobiliser » la graisse corporelle. Considérée par un public plus averti comme un simple placebo, principalement car aucune étude (jusqu’à très récemment) n’avait réussi à prouver sa réelle efficacité quant à accélérer ou faciliter la perte de masse graisseuse.

Carnitine : Facts or Fiction

Version française

Carnitine as a fat burner

Carnitine, much like creatine (even though their functions are quite different) is a supplement that has been available for years (even decades). It has always been categorized by common wisdom as a « fat burner » or « fat mobilizer », and considered by better informed parties as a placebo product because no study (until very recently) had been able to prove the efficacy of oral carnitine supplementation regarding fat oxidation.

The benefits of physical activity on brain health and cognitive functions

brain health simpson'sVersion française ici

We are constantly reminded of how exercise affects positively our physiology as well as our esthetics, and how important it is to stay physically active throughout life to age well. And although these considerations have real value, I think it is a bit limited.

Indeed, we are now starting to realize, thank to a constant progress of science, that our body is an integrated system, and that no action, or influence imposed on our body (understand  « body » as a whole, not just the bony/fleshy mechanical envelope) wether external or internal, can be looked at from a restricted and limited point of view, and that for an actual response to a given stimulus to occur, the entire human mechanism is put in motion in a holistic way.

Let me illustrate this with an example related to health and fitness :

If John wants bigger biceps (endurance athletes/enthusiasts please stay with me, this concerns you also, just think of John as a triathlete getting ready for an IronMan run), he is going to go to the gym and engage in a particular routine that will focus on stimulating his biceps, and hopefully, he will end up with bigger guns… But the reality of what is happening isn’t limited to his biceps brachii muscles.  A host of endocrine, nervous, muscular, conscious and unconscious reactions are going to occur to allow for his biceps to be trained and later on, if the adequate anabolic environment is provided, grow.

This was a lengthy introduction but I think this point needed to be made : Whatever your goals or your speciality in life, even if those are more of an intellectual nature, you should ALWAYS look at your body as an intricate, interrelated system and how this relates to your daily performances.

To illustrate this essential fact, and to give substance to my allegations, I am going to introduce you to a fact that might be new to you : Physical activity has the potential to increase cognitive functions, orientation and improve overall emotional state. Continue reading
