What is Intermittent Fasting?

This is a dietary regimen that limits food consumption to set intervals. The most common option is the 16/8 scheme: 16 hours without food and 8 hours for meals. Scientific studies indicate that this regimen has several positive effects:

• reduces the number of snacks,
• promotes weight loss,
• activates the burning of fat reserves after glycogen depletion, which occurs approximately 12 hours into fasting,
• increases cell sensitivity to insulin, reducing the risk of developing type 2 diabetes.

Who Should Avoid Intermittent Fasting?

Despite numerous benefits, this regimen is not suitable for everyone and may harm certain groups of people. The dietitian identifies the following categories:

1. People with Type 1 Diabetes: Fasting periods can cause a sharp drop in blood sugar levels, accompanied by weakness, fatigue, and dizziness.
2. Individuals with Eating Disorders: Strict dietary restrictions can worsen psychological conditions and exacerbate negative habits.
3. People with Weakened Immune Systems: Their bodies require a regular supply of nutrients, and fasting only weakens protective functions.
4. Pregnant and Breastfeeding Women: Prolonged fasting can increase cortisol levels (the stress hormone), disrupt hormonal balance, menstrual cycles, and reproductive function.

Thus, intermittent fasting can be effective for weight loss and improving metabolic health, but it is important to consult a doctor or dietitian before starting, especially if you belong to a risk group.
