Thoughts and body: inextricably linked "think slim"

July 31, 2025Fajah Lourens

Thoughts and body: inextricably linked
Our mind and body form a single, integrated system. What happens in your mind, such as repetitive worries or ruminations, unconsciously activates your body's stress system. This process is known as "perseverative cognition": the constant reliving or anticipation of stressful events. Research shows that this persistent thought activity leads to increased heart rate, blood pressure, and cortisol levels, even when there is no immediate threat.

The role of the HPA axis and cortisol
When your body experiences a stressful stimulus, the hypothalamic–pituitary–adrenal (HPA) axis initiates a chain reaction that culminates in the release of cortisol. This hormone is designed to make you alert and energetic in acute situations. However, with chronic stress or persistent negative thoughts, the HPA axis remains activated. Long-term elevated cortisol levels promote fat storage, particularly around the abdominal area, and inhibit fat burning.

From thinking to eating: the pitfall of 'comfort food'
Cortisol influences not only fat storage but also your appetite. Research shows that elevated cortisol levels lead to a preference for energy-rich, fatty, and sweet foods. These "comfort foods" offer temporary relief by stimulating the release of dopamine and endorphins, but they also contribute to weight gain and a disrupted relationship with food.

Awareness as the first step
Recognizing that thoughts have a direct physical impact is crucial. By pausing to observe your automatic thought patterns without judgment, you can break the chain of stress activation.
