Sleep is important. Did you know that it is important to weight loss and maintaining a healthy weight? Recent studies have shown a link between sleep and the hormones that influence our eating behaviors.

The Appetite Decreasing Hormone, Leptin

  • Signals the brain that your body has enough energy stores (fat) to function normally
  • Responsible for making you feel “full” when eating
  • Thought to signal hunger to the brain

The Appetite Increasing Hormone, Ghrelin

  • Thought to signal hunger to the brain
  • High levels of ghrelin appear to strongly increase our drive for high-calorie foods
  • Ghrelin may influence our eating behavior by increasing the stimulation of the brain’s reward system

How Leptin and Ghrelin Work

Working together, these two hormones let us know when we are hungry and when we are full.

A Lack of Sleep is a Recipe for Overeating

A lack of sleep decreases leptin levels, which makes you feel less satisfied after eating. It also increases ghrelin, stimulating your appetite and increasing your drive for high-calorie foods.

In a study by the University of Chicago, high levels of ghrelin were shown to “reduce energy expenditure, stimulate hunger and food intake, promote retention of fat and increase hepatic glucose production to support the availability of fuel to glucose dependent tissues.”

How Much Sleep is Enough Sleep?

  • 8.5 hours of sleep is ideal, promoting optimal levels of leptin and ghrelin levels
  • 5.5 hours or less of sleep increases ghrelin levels
