Harvard Health Blog: Sleep impacts our eating patterns, and our eating patterns impact our sleep.
The National Sleep Foundation recommends that adults should get seven to nine hours of sleep a night. However, according to the CDC, only one in three adults is meeting these guidelines. At the same time people are struggling with sleep, they are also struggling with their weight and with making healthful food choices. One research study demonstrated that subjects who slept only four hours of sleep ate 300 more calories per day, compared to those who got nine hours of rest.
When we are sleep-deprived, the hormones that affect appetite and fullness are disrupted. Ghrelin increases our appetite, and leptin plays an important role in helping us feel full.
When we don’t get enough sleep, ghrelin increases and leptin decreases. Researchers looked at 495 women’s sleep patterns, their daily quantity of food, and quality of food. They found that poor sleep quality was correlated with greater intake of food and lower diet quality.
