Nutritionist Warns About the Health Risks of Intermittent Fasting

The popular method of intermittent fasting, despite its widespread use, can cause serious harm to health, warns nutritionist and dietitian Tatiana Meshcheryakova.

According to the specialist, prolonged periods of food deprivation often lead to a deficiency of essential nutrients and provoke stress, which causes a release of cortisol—the stress hormone. Additionally, intermittent fasting is accompanied by sharp fluctuations in blood glucose levels, whereas regular meals help stabilize it. This can negatively affect overall metabolism, which slows down under such eating patterns.

The nutritionist notes that regular meals in small portions contribute to more effective gastrointestinal function and a lower risk of stomach issues, such as heartburn and bloating.

Meshcheryakova paid special attention to the psycho-emotional consequences of intermittent fasting. Some individuals may experience anxiety, guilt, and a negative attitude towards food, which increases the risk of developing eating disorders.

Who Should Avoid Intermittent Fasting

• People with chronic diseases: diabetes, gastritis, gallbladder, liver, and kidney diseases;
• Pregnant women and those breastfeeding;
• Teenagers in a phase of active growth;
• Individuals with eating disorders;
• Workers with irregular schedules and heavy physical labor.

Nutritionists also warn about the risks of increasing "bad" cholesterol and decreasing muscle mass when intermittent fasting is not followed correctly, which can mislead individuals regarding changes in body weight.

Thus, while intermittent fasting may seem like a convenient and effective way to control weight, it requires a careful and informed approach considering individual body characteristics. It is recommended to consult a doctor or nutrition specialist before starting such a diet.
