Cortisol is an essential hormone that regulates blood glucose, metabolism, inflammation, blood pressure and our sleep-wake cycle. It naturally rises in the morning to support alertness and declines throughout the day to support sleep. Chronically elevated or dysregulated cortisol can contribute to metabolic imbalances, disrupted sleep and increased abdominal fat.
What do carbohydrates have to do with cortisol?
When blood glucose drops too low, the body releases cortisol and other hormones to help restore it. Eating enough, including nourishing carbohydrates, supports healthy blood glucose regulation and energy levels.
Carbohydrates also help support calm during stress.
Glucose provides essential energy for the brain. Carbohydrates also influence tryptophan availability, supporting serotonin production, which plays a role in mood regulation and emotional well-being. For those experiencing stress or under-eating, adequate carbohydrates can support energy, mood and a greater sense of calm.
When should you eat carbohydrates?
Including whole-food carbohydrates at lunch and dinner supports sustained nourishment throughout the day.
Choose sweet potatoes, potatoes, legumes, squash and root vegetables, paired with protein, fiber and healthy fats to support balanced blood glucose responses.
Why are evening carbohydrates important?
Carbohydrate intake stimulates insulin release, influencing the availability of tryptophan to enter the brain. Tryptophan is used to produce serotonin, which is subsequently converted into melatonin, the hormone that regulates our sleep-wake cycle.
This established biological pathway connects carbohydrate metabolism with sleep-related processes. Including nourishing carbohydrates at dinner also supports adequate energy intake and helps prevent hunger from disrupting sleep.
What does sleep have to do with belly fat?
Restorative sleep supports healthy cortisol rhythms, insulin sensitivity, appetite regulation and metabolic health, all important for healthy weight management.
The takeaway?
Reducing abdominal fat involves more than restricting calories or carbohydrates.
Eating enough, including nourishing carbohydrates at lunch and dinner, managing stress and supporting restorative sleep helps your body maintain healthy metabolic balance.
