More and more informationn is being discovered about the importance of getting 7-8 hours of quality sleep each night. In terms of weight loss, a lack of sleep affects our ability to lose weight by interfering with the hormonal processes that take place while you sleep.
The two hormones that are key in this process are ghrelin and leptin. Leptin is the hormone that tells you to stop eating, and when you are sleep deprived, your body makes less leptin. Ghrelin is the hormone that tells you when to eat. When you are sleep-deprived, your body makes more ghrelin. The result? Your body is telling you to eat more and your body is not telling you when to stop. In other words more ghrelin + less leptin = weight gain.
Keep a sleep log to see if you are getting 7-8 hours of sleep a night. If you are not, make a list of the barriers that prevent you from getting 7-8 hours of sleep. Are your barriers to quality sleep things that you have the ability to change? If so, what can you do differently to get your ZZZ’s?
