Discover how cortisol (Stress hormone) contributes to body weight fluctuations

What Is Cortisol?

Cortisol is a steroid hormone released by the adrenal glands (above the kidneys). It is controlled by the hypothalamic-pituitary-adrenal (HPA) axis and secreted in response to stress.
Cortisol is good when used in tiny amounts. It helps with:

  • Maintaining Blood Pressure

  • Controlling blood sugar

  • Increasing energy during "fight-or-flight" responses.

  • Controlling inflammation.

The problem arises when cortisol levels remain excessive for an extended period of time, which is frequent in today's high-stress lifestyles.

How Cortisol Affects Weight

Increased appetite and cravings
High cortisol levels might increase your appetite, particularly for high-calorie, sugary, and fatty foods. This is why stress often leads to comfort eating.


Belly Fat Storage
Cortisol results fat storage to the abdomen area. This "visceral fat" surrounds internal organs and has been linked to an increased risk of diabetes and heart disease.

Reduced Rate of Metabolism
Your body slows down calorie expenditure when cortisol levels are consistently high because it is conserving energy. Even with exercise, this makes losing weight more difficult.


Resistance to Insulin and Blood Sugar
When you're under stress, cortisol causes your blood sugar to rise. This could eventually result in insulin resistance, which would make controlling weight more difficult.


Cortisol imbalance symptoms
How can you tell whether your weight is being impacted by cortisol?

Seek: Constant belly fat in spite of good behaviours; frequent sugar cravings; exhaustion or energy slumps; mood swings, worry, or irritation and poor sleep quality.

Symptoms of Cortisol Imbalance

How do you know if cortisol may be affecting your weight?

Confirm it by following these symptoms:

  •  Persistent belly fat despite a healthy lifestyle and a balanced diet

  •  Frequent sugar craving, i.e chocolates and cakes

  •  Fatigue or low energy

  •  Mood swings, anxiety, or stress

  •  Poor sleep quality or insomnia

How to manage cortisol to Improve Weight Loss


The good news is that you can modify your lifestyle to promote a healthy cortisol balance.


Make sleep a priority; getting 7 to 9 hours aids with cortisol regulation.


Exercise sensibly: While excessive training might increase cortisol, moderate exercise lowers stress.


A balanced diet should contain fibre, protein, and good fats to help control blood sugar levels.


Stress reduction: The HPA axis is calmed by yoga, meditation, and breathing techniques.


Standard testing: Request blood, saliva, or urine testing from your physician if you think your cortisol levels are elevated.


In conclusion


Cortisol isn't the enemy; it's necessary for survival. However, if stress levels remain high, it can lead to weight gain, belly fat, and halted progress. By managing stress, increasing sleep, and promoting hormonal balance, you can make cortisol an ally rather than an enemy in your weight loss quest.


The next time you're fighting with stubborn weight, realize that it might not be simply about calories. Your hormones, particularly cortisol, may be the missing piece of the puzzle.

Q2

How rapidly might cortisol levels decline due to lifestyle changes?
Individuals' cortisol levels vary, but regular stress management strategies such as meditation, better sleep, and balanced nutrition can begin to improve within a few weeks.
