Eating for Better Sleep & Foods that Improve Metabolic Health | Dr. Marie-Pierre St-Onge

Key takeaways

Higher fiber intake is linked to more deep sleep, while saturated fats and refined carbohydrates can disrupt sleep quality.
There is a bidirectional relationship between sleep and food choices, meaning that what you eat can affect your sleep and vice versa.
Dr. St-Onge's research shows that modest sleep deprivation can lead to increased hunger, with different hormonal responses in men and women.
A study indicated that individuals who sleep 5-6 hours per night gained more weight over 14 years compared to those who slept 7-8 hours.
On average, participants in a sleep-restricted study consumed 300 more calories when sleep-deprived compared to when they had adequate sleep.
Increase fiber intake in your diet to promote better sleep quality and enhance metabolic health.
