# Sueño y pérdida de grasa

Misma dieta, 5,5 h frente a 8,5 h de sueño: un 55 % menos de grasa perdida. El sueño es una herramienta para perder grasa.



## Claves

- Duerme ≥ 7 h en dieta o perderás músculo, no grasa.

- Dormir poco = más hambre y menos sensibilidad a la insulina.

- Pésate a diario o semanalmente y compáralo con tu sueño.
