What is cortisol?
Cortisol, also known as glucocorticoids, is a crucial hormone produced by the adrenal gland in the human body. It plays an essential role in various psychological processes. Some of the functions of cortisol include:
1. It aids in the breakdown of carbohydrates, fats, and protein.
2. Cortisol helps regulate blood pressure and maintains the body’s fluid balance.
3. It is also a key component in several hormones controlling sexual and growth functions.
Cortisol is generally released in close association with your body’s circadian rhythm. The pituitary gland and hypothalamus regulate its production and release. While the normal release of cortisol preps the body to fight any potentially harmful situation, persistent elevations can have negative side effects.
Can cortisol affect weight loss efforts?
When cortisol levels are within the normal range, it is essential for proper nourishment and overall well-being. In this case, cortisol does not impede weight loss efforts. However, excessive cortisol introduced into the body through medications like steroids can lead to weight gain. Therefore, in such cases, it becomes necessary to stop using steroids or opt for steroid-sparing drugs to facilitate weight loss.
High levels of cortisol or stress can lead to overeating. Some people have chronically elevated cortisol levels due to extreme stress or a condition called Cushing’s Syndrome. Side effects of high cortisol include weight gain, elevated blood pressure, tiredness, mood swings, thinning of the skin, irritability, difficulty in focusing, and insulin resistance.
Under chronic stress, it becomes tedious to maintain healthy eating habits. If cortisol levels are normal and no additional cortisol is taken, it will not hinder weight loss strategies. Only when cortisol levels become abnormally high due to external factors does it interfere with weight loss.
“It is important to note that cortisol is a vital hormone with many essential functions in the body. However, chronic stress and sustained high cortisol levels, often caused by ongoing stressors, can have negative effects on various aspects of health, including weight management. Managing stress through lifestyle changes, such as relaxation techniques, regular exercise, and a balanced diet, can help mitigate the negative impacts of cortisol on weight loss efforts,” says the expert.
