Si vous suivez religieusement les prot\u00e9ines mais que vous pensez \u00e0 peine aux fibres, vous laissez la performance sur la table. Les fibres ne se contentent pas de soutenir la digestion et la pr\u00e9vention \u00e0 long terme des maladies \u2014 elles influencent directement votre contr\u00f4le de l\u2019app\u00e9tit, la stabilit\u00e9 \u00e9nerg\u00e9tique et l\u2019efficacit\u00e9 avec laquelle votre corps absorbe les nutriments qui alimentent votre entra\u00eenement. Pour quiconque cherche \u00e0 perdre de la graisse ou \u00e0 prendre du muscle, c\u2019est l\u2019un des leviers les plus n\u00e9glig\u00e9s dans ce r\u00e9gime.<\/p>

Les chiffres rendent cet \u00e9cart \u00e9vident. La recommandation de consommation ad\u00e9quate de l\u2019USDA est de 25 grammes par jour pour les femmes et 38 grammes par jour pour les hommes, alors que l\u2019adulte am\u00e9ricain moyen ne consomme qu\u2019environ 15 grammes. R\u00e9duire cet \u00e9cart peut changer de mani\u00e8re significative votre ressenti et votre performance, \u00e0 l\u2019int\u00e9rieur comme \u00e0 l\u2019ext\u00e9rieur de la salle de sport.<\/p>

Soluble vs. insoluble : conna\u00eetre la diff\u00e9rence<\/h2>

La fibre n\u2019est pas une seule chose \u2014 c\u2019est une cat\u00e9gorie avec deux types fonctionnels, et vous avez besoin des deux.<\/p>

Fibres solubles<\/h3>

Ce type absorbe l\u2019eau pendant la digestion, formant une substance g\u00e9latineuse qui ralentit le vidange de l\u2019estomac et aide \u00e0 stabiliser la glyc\u00e9mie. Cette digestion plus lente est ce qui vous permet de vous sentir rassasi\u00e9 plus longtemps. De bonnes sources incluent l\u2019avoine, les lentilles, les pommes, les agrumes et les carottes.<\/p>

Fibres insolubles<\/h3>

Ce type ne se dissout pas et ajoute plut\u00f4t du volume aux selles, soutenant la motilit\u00e9 intestinale normale. Vous en trouverez dans les l\u00e9gumes-feuilles, les noix, les graines et les avocats.<\/p>

Comment la fibre soutient vos objectifs d\u2019entra\u00eenement<\/h2>

Contr\u00f4le de l\u2019app\u00e9tit pour la perte de graisse.<\/strong>Les aliments riches en fibres sont g\u00e9n\u00e9ralement plus faibles en calories et mettent plus de temps \u00e0 dig\u00e9rer, ce qui prolonge la sati\u00e9t\u00e9 et r\u00e9duit l\u2019envie de trop manger. Recherches publi\u00e9es dansCritical Reviews in Food Science and Nutrition<\/em>montre que la fermentation des fibres d\u00e9clenche des hormones intestinales comme le GLP-1 et le peptide YY, qui signalent toutes deux une sensation de sati\u00e9t\u00e9 au cerveau. En pratique, privil\u00e9gier les aliments riches en fibres fait souvent le travail de comptage les calories sans suivi constant.<\/p>

Des niveaux d\u2019\u00e9nergie plus stables.<\/strong>Parce que les fibres ralentissent l\u2019absorption des glucides, elles aident \u00e0 pr\u00e9venir les pics et chutes de la glyc\u00e9mie qui vous laissent lent entre les entra\u00eenements. Une \u00e9nergie plus stable se traduit par une intensit\u00e9 d\u2019entra\u00eenement plus r\u00e9guli\u00e8re et une meilleure adh\u00e9sion \u00e0 votre programme.<\/p>

Meilleure absorption des nutriments \u2014 avec une r\u00e9serve concernant le timing.<\/strong>La digestion lente qui rend les fibres si utiles pour contr\u00f4ler l\u2019app\u00e9tit agit contre vous imm\u00e9diatement apr\u00e8s l\u2019entra\u00eenement. Dans la fen\u00eatre de 30 \u00e0 45 minutes apr\u00e8s l\u2019entra\u00eenement, votre corps a besoin de glucides et prot\u00e9ines \u00e0 digestion rapide pour la r\u00e9cup\u00e9ration \u2014 pas que les fibres ralentissent cette livraison. Gardez vos repas riches en fibres pour plus t\u00f4t dans la journ\u00e9e et gardez votre repas ou shake post-entra\u00eenement l\u00e9ger en fibres.<\/p>

\"\"\/<\/figure>

Moyens pratiques de combler l\u2019\u00e9cart<\/h2>
  • Swap refined grains for oats, quinoa, or whole-grain bread.<\/li>
  • Add a serving of legumes (lentils, chickpeas, black beans) to one meal a day.<\/li>
  • Keep fruit with the skin on \u2014 most of the fiber lives there.<\/li>
  • Build a fiber-forward smoothie for breakfast or a midday snack.<\/li> <\/ul>

    Essayez cette combinaison, qui s\u2019accorde bien avec une fen\u00eatre d\u2019entra\u00eenement matinale lorsqu\u2019elle est mang\u00e9e 1 \u00e0 2 heures avant :<\/p>

    • 2 cups spinach<\/li>
    • \u00bd avocado<\/li>
    • \u00bd banana<\/li>
    • \u00bd cup almond milk<\/li>
    • 1 tsp vanilla extract<\/li> <\/ul>

      Si vous \u00eates bien en dessous de votre objectif de fibres, augmentez progressivement votre apport sur quelques semaines \u2014 un saut soudain peut provoquer des ballonnements ou des inconforts digestifs. Associez toute augmentation \u00e0 un exc\u00e8s d\u2019eau, car les fibres solubles ont besoin de liquide pour faire leur travail.<\/p>

      \"\"\/<\/figure>

      Le r\u00e9sultat final<\/h2>

      Les fibres sont rarement le nutriment principal dans les discussions sur le fitness, mais elles influencent discr\u00e8tement l\u2019app\u00e9tit, l\u2019\u00e9nergie et la r\u00e9cup\u00e9ration chaque jour. Visez 25 \u00e0 38 grammes par jour selon votre sexe et votre taille, r\u00e9partissez les repas, et gardez vos aliments plus l\u00e9gers et plus digestifs pour juste apr\u00e8s l\u2019entra\u00eenement.<\/p>
