The Link Between Stress and Overeating

In today's world, stress has become an integral part of our daily lives. Workloads, family responsibilities, and the constant flow of information—all of these can cause tension and anxiety. Many of us have noticed that in stressful situations, we feel the urge to eat something sweet or high in calories. But why does this happen? How are stress and overeating connected at the physiological level, and what can be done to cope with this phenomenon? In this article, we will take a closer look at these questions.

Physiological Mechanisms: Cortisol and Insulin

Cortisol — the Stress Hormone

When we face a stressful situation, the body launches a complex cascade of physiological reactions, known as the "fight or flight" response. One of the key elements of this reaction is the production of the hormone cortisol by the adrenal glands.

• Cortisol’s Functions:

  • Increases blood glucose levels to provide rapid access to energy.
  • Supports the functioning of the cardiovascular system.
  • Suppresses functions that are not essential at the moment (such as digestion and growth).

• The effect of cortisol on appetite:

  • Cortisol can stimulate appetite, especially for foods high in fat and sugar.
  • Chronically elevated cortisol levels are associated with the accumulation of visceral fat (around internal organs).

Insulin and Its Role

Insulin is a hormone produced by the pancreas, whose main function is to regulate blood glucose levels.

• The connection between insulin and cortisol:

  • An increase in cortisol leads to elevated blood glucose levels.
  • Insulin is released to lower blood glucose, aiding its absorption by cells.
  • Fluctuations in insulin levels can affect feelings of hunger and cravings for carbohydrates.

• Insulin resistance:

  • Chronic stress and consistently high cortisol can lead to reduced insulin sensitivity in cells.
  • This carries a risk of type 2 diabetes and contributes to weight gain.

Stress Eating: Why Do We Eat More in Stressful Situations?

Emotional Eating

• Seeking comfort:

  • Food, especially rich in sugars and fats, can stimulate the production of "happy hormones"—serotonin and dopamine.
  • This temporarily improves mood and reduces feelings of stress.

• Habit formed in childhood:

  • Many of us as children received treats as a reward or for comfort, which established the link between food and emotional comfort.

Physiological Factors

• Increased appetite:

  • Cortisol directly increases feelings of hunger.
  • Stress can disrupt the balance of the hormones responsible for appetite—ghrelin and leptin.

• Sleep disturbance:

  • Stress often leads to sleep problems.
  • Lack of sleep increases ghrelin levels (the hunger hormone) and decreases leptin levels (the satiety hormone).

How to Cope with Stress Eating

1. Mindfulness and Self-Monitoring

• Keep a food diary:

  • Record what and when you eat, as well as your emotional states.
  • This will help you identify connections between stress and eating.

• Practice mindful eating:

  • Eat slowly, focusing on the taste and texture of food.
  • Listen to your body's hunger and fullness cues.

2. Stress Management

• Physical activity:

  • Regular exercise reduces cortisol levels and boosts endorphin production.
  • Choose an activity you enjoy: yoga, running, swimming, dancing.

• Relaxation techniques:

  • Meditation, deep breathing, progressive muscle relaxation.
  • They help calm the mind and reduce the body’s physiological stress response.

• Hobbies and creativity:

  • Activities that bring joy can distract from negative thoughts and lower stress levels.

3. Healthy Sleep

• Set a consistent sleep schedule:

  • Go to bed and wake up at the same time each day.

• Create a comfortable sleep environment:

  • Darkness, silence, and a comfortable bed.

• Limit gadget use before bed:

  • Blue light from screens disrupts melatonin production.

4. Rational Eating

• Balanced diet:

  • Include foods rich in proteins, healthy fats, and complex carbohydrates in your meals.

• Regular meals:

  • They help maintain stable blood sugar levels and prevent sudden hunger attacks.

• Avoid "fast" sugars:

  • They cause rapid insulin spikes and intensify cravings for sweets.

5. Seeking Support

• Psychological help:

  • If stress eating becomes a constant problem, consult a psychologist or psychotherapist.

• Support groups:

  • Communicating with people facing similar challenges can be helpful.

---

Stress and overeating are connected by complex physiological and psychological mechanisms. Understanding how hormones like cortisol and insulin affect our appetite and behavior is the first step in taking control of the situation. Combating stress eating requires a comprehensive approach: stress management, healthy lifestyle, mindful eating, and, if necessary, professional support. Remember, taking care of yourself is not a luxury, but a necessity for physical and emotional well-being.

Take care of yourself and stay healthy!
