Cétones exogènes: pour ou contre?

Pour ou contre les cétones exogènes

Les cétones exogènes, c’est un sujet très controversé. Il y a des gens qui ne jurent que par ça et d’autres qui disent qu’il ne faut pas y toucher. Habituellement quand c’est aussi controversé, la vérité est quelque part entre les deux.

Pour clarifier le sujet, j’ai fait un vidéo disponible sur YouTube :

Bref résumé du vidéo

Note : Toutes les opinions exprimées ici sont les miennes. Cet article peut contenir des liens d’affiliés et je peux recevoir une commission, sans frais supplémentaires pour vous. Mais je ne propose toujours que des produits que j’utilise (ou utiliserais) moi-même. Consultez l’avis de non-responsabilité ici. Merci de soutenir mon travail!

Une cétone, c’est d’abord une molécule produite par le corps à partir des gras lorsque les glucides ne sont pas disponibles (ou épuisés). En effet, le corps produit naturellement des cétones durant le jeûne, la diète céto, les sports d’endurance (si on ne lui donne pas constamment de glucides) et à la naissance. C’est un carburant super efficace et propre dont la production est inhibée par les glucides et la résistance à l’insuline.

Cétones exogènes et alimentation

Il faut d’abord savoir que les cétones exogènes ne remplacent ni une bonne alimentation, ni le jeûne. Personne ne peut manger de la chnoutte et être en santé juste en prenant des cétones. Elles peuvent être utiles pour aider à se sortir de là, mais pour améliorer la santé, il faut changer l’alimentation. Point.

Utilité des cétones

En revanche, les cétones exogènes augmentent l’efficacité de la diète céto sur la glycémie et le taux de cétones.

Elles sont aussi utiles pour plusieurs indications :

  • Amélioration du contrôle de la glycémie
  • Diminution de la faim (aide à moins manger)
  • Effet neuroprotecteur
  • Effet cardioprotecteur
  • Effet énergisant
  • Diminution de l’inflammation (partout, même dans l’intestin)
  • Épilepsie : amélioration de l’effet de la diète céto
  • Amélioration de la récupération post exercice
  • Etc.

Risques

Les cétones exogènes sont très sécuritaires. Mais faites attention aux additifs (édulcorants et colorants de synthèse) présents dans les différents produits. Tous les produits vendus sur le marché ne sont pas égaux. Personnellement, je consomme régulièrement des cétones et j’ai choisi les cétones Prüvit parce que la formulation est intéressante. Les dosages sont intéressants et les saveurs et édulcorants qu’ils contiennent sont tous d’origine naturelle.

On entend parfois parler d’un effet sur la production endogène. J’en discute vers la fin du vidéo. J’y donne aussi beaucoup plus de détails sur les différents points mentionnés ci-haut et je m’attarde également aux mécanismes d’action.

Conclusion

Pour moi, les cétones exogènes sont des outils parmi d’autres. Ils ont leur utilité, surtout lorsque l’énergie n’est pas au rendez-vous, mais ils ne sont pas « bons pour tout ».
