Exercise is not only good for the body, but also influences hormone production, especially the well-known cortisol. This hormone, often referred to as the "stress hormone", plays a key role in the body's adaptation to stressful situations, whether physical or psychological.

Cortisol in the context of physical activity
During physical activity, the body experiences stress at a cellular level. This leads to a temporary increase in cortisol levels. In the short term, this is normal and even beneficial, as cortisol helps the body to release energy and deal with the challenges of activity.

The challenge: Chronically elevated cortisol
However, problems can arise when cortisol levels remain chronically elevated, whether due to excessive exercise, lack of sleep or other stressful life circumstances. This can lead to undesirable effects, including muscle loss, impaired immune function and even problems with weight management.

Will cortisol prevent me from losing weight?
The role of cortisol in weight loss is complex and can be influenced by various factors. Cortisol is often referred to as the "stress hormone" because its levels rise in stressful situations, whether physical or psychological. Here are some aspects to consider:

  • Fat distribution: chronically elevated cortisol levels can affect fat distribution in the body, particularly in the abdominal area. This is sometimes referred to as a "stress belly".
  • Appetite regulation: Cortisol can affect appetite, and some people tend to eat more in stressful situations, especially high-calorie and high-carbohydrate foods.
  • Insulin resistance: Long-term elevated cortisol levels can increase insulin resistance, which affects blood sugar levels and can lead to altered energy utilization.
  • Muscle breakdown: Excessive cortisol can promote the breakdown of muscle tissue, which in turn can reduce the basal metabolic rate.

It is important to note that the effects of cortisol can vary from person to person, and not everyone will respond in the same way. In addition, regular physical activity and a balanced diet can help to mitigate the negative effects of cortisol.

When is cortisol bad for me?
Cortisol is a vital hormone that plays a crucial role in the body. However, it is not "bad" per se. Cortisol is part of the natural stress response system and has important functions, including mobilizing energy sources, regulating the immune system and adapting to stressful situations.

Nevertheless, chronically elevated cortisol levels due to prolonged stress or other factors can have detrimental effects on health. Here are some situations in which high cortisol levels can be considered detrimental:

  • Chronic stress: continuous stress can lead to a permanent increase in cortisol levels, which can be associated with negative effects on the body. This can lead to problems such as sleep disorders, weight gain, high blood pressure and weakened immune function.
  • Lack of sleep: Insufficient or disrupted sleep can lead to increased cortisol levels, which in turn can disrupt hormone balance and contribute to various health problems.
  • Excessive exercise: Intense and excessive physical exercise can lead to increased cortisol levels, which can lead to muscle breakdown, fatigue and impaired recovery.
  • Mental illness: Cortisol levels may be affected in some mental illnesses, such as depression or anxiety disorders.
  • Unbalanced diet: A poor diet, especially excessive consumption of foods high in sugar and carbohydrates, can lead to dysregulation of hormone levels, including cortisol.
