Cortisol
Cortisol is a steroid hormone produced from cholesterol in the adrenal glands located on top of each kidney. It is released upon awaking, and in response to exercise and acute stress. Blood levels vary throughout the day and are usually highest in the morning and lowest at night.
Cortisol plays an important role in nutrition, and regulates energy by selecting the right type and amount of substrate (carbohydrate, fat, or protein) the body needs to meet the physiological demands placed on it. When chronically elevated, it can have harmful effects on weight, immune function, and chronic disease risk.
