You might not be hungry in the morning due to overnight fluctuations in your hormone levels.
Hormonal shifts that occur while you sleep can significantly impact your appetite upon waking. According to research, hormones like adrenaline, ghrelin, and leptin fluctuate overnight and in the morning, which can leave you feeling less hungry when you wake up (07-Jun-2021).
Here's a simplified breakdown:
- Adrenaline: Often associated with the "fight or flight" response, adrenaline levels tend to be higher in the morning. This can suppress hunger.
- Ghrelin: Known as the "hunger hormone," ghrelin stimulates appetite. Its levels typically decrease overnight.
- Leptin: The "satiety hormone," leptin signals fullness. Levels are generally higher overnight, potentially reducing morning hunger.
Therefore, the interplay of these hormonal changes can explain why you might not feel hungry right after waking up.
