The Sleep-Appetite Connection

Ep 48 (2)
In this episode of ReInvent Healthcare, we will discuss the relationship between lack of sleep and appetite. We go in-depth into the different hormones that are affected by sleep and how these can trigger hunger. We will also discuss the different areas in the brain that can affect appetite.


  • [04:30] Sleep deprivation and increased Ghrelin production resulting in food cravings
  • [05:30] Lower Leptin levels and increased food consumption
  • [7:00] The importance of Adiponectin
  • [9:45] Neuropeptide Y appetite stimulation
  • [12:00] Lack of sleep and the areas in the brain that affect appetite


  • Children need at least 11 hours of sleep. Studies have shown that those with lack of sleep have a higher risk of obesity. 

  • Sleep deprivation significantly decreases activity in appetite evaluation regions within the frontal cortex and can therefore trigger hunger

  • Lack of sleep can induce high levels of cortisol and can lead to intense cravings, resulting in binge eating
