# Sommeil et perte de gras

Même régime, 5,5 h contre 8,5 h de sommeil : 55 % de gras perdu en moins. Le sommeil est un outil de perte de gras.



## À retenir

- Dormez ≥ 7 h en régime, sinon vous perdez du muscle, pas du gras.

- Sommeil court = plus de faim, moins de sensibilité à l'insuline.

- Pesez-vous chaque jour ou chaque semaine ; comparez au sommeil.
