Contexte : Le jeûne intermittent (JI) suscite un intérêt croissant en tant que méthode efficace pour lutter contre l’obésité.
Objectif : Comparer les effets du jeûne intermittent 16:8 (JI 16:8) et de la restriction calorique continue (RCC) sur les paramètres anthropométriques et les composants du syndrome métabolique chez des femmes obèses.
Méthodes : Un essai clinique contrôlé non randomisé a été mené auprès de femmes obèses suivies pendant trois mois. Les patientes ont été réparties en deux groupes : JI (45 patientes) et RCC (55 patientes), chacune ayant une réduction calorique de 25 %. Les paramètres anthropométriques, la composition corporelle et le profil métabolique ont été évalués.
Résultats : L’âge moyen était de 34,10 ± 8,44 ans dans le groupe JI et de 34,62 ± 8,80 ans dans le groupe RCC, avec des IMC respectifs de 38,63 ± 5,15 kg/m² et 34,84 ± 6,69 kg/m². Les deux groupes ont connu une perte de poids significative après trois mois, avec une perte plus importante dans le groupe JI (-7,38 ± 4,1 kg contre -5,41 ± 3,84 kg, p=0,03). La réduction de la masse grasse et du tour de taille était plus marquée dans le groupe JI (p=0,04 et p=0,0001, respectivement). De plus, le JI s’est révélé plus efficace que la RCC pour réduire la glycémie (p=0,04) et les triglycérides (p=0,02) et pour augmenter le HDL-cholestérol (p=0,01). La fenêtre alimentaire précoce (de 8h à 16h) dans le groupe JI était associée à des réductions plus importantes du poids,..(résumé tronqué à 250 mots).
