Dr. Sövényházi Ilona: Már heti egy böjtnap is jó lehet a szervezetnek | Az Én Kék Zónám #90

Summary

Dr. Sövényházi Ilona discusses fasting as a structured practice that, in her view, can support physical and mental well-being—not simply as a weight-loss diet. Drawing on her experience leading group juice fasts, she emphasizes that fasting should be approached carefully, with preparation, recovery, and medical screening.

Key strategies and advice

• Prepare gradually: Before a longer fast, participants reduce their food intake step by step to help the body adjust.
• Follow a structured fast: The juice-fast routine she describes includes herbal tea, small portions of diluted fresh juice, strained vegetable broth, lemon water, and plenty of water. Her groups generally follow five- to seven-day programs.
• Make recovery part of the fast: She emphasizes that returning to food gradually is essential. Participants receive a specific plan for the first three days after fasting; eating too much too soon can cause nausea, vomiting, and feeling unwell.
• Keep activity flexible: Walking, hiking, yoga, and other gentle exercise may be part of a program, but participants should rest if they feel weak or need solitude. She reports that some feel more energetic after an initial adjustment period.
• Consider a weekly fasting day: Sövényházi says one day a week may be a manageable way to give digestion a break. She suggests choosing a regular weekday, or moving the fast earlier rather than postponing it if that day is not possible. Options she describes include water or tea, as well as a juice-fast format.
• Personalize intermittent fasting: She says eating windows should depend on a person’s metabolism, routine, and lifestyle. In her view, a 12-hour overnight break may mainly provide digestive rest, while a longer break may bring more of the effects associated with fasting.
• Use supportive surroundings: She favors a quiet group retreat over attempting a first fast alone amid regular work and home routines. She describes the group setting as helpful for relaxation, reflection, and motivation.
• Treat fasting as more than a weight-loss method: She says weight loss during a fast is often largely water, and that fasting is not a reliable long-term weight-management strategy. She describes possible emotional benefits, such as renewed self-confidence and clearer thinking, as experiences reported by participants.
• Seek professional guidance and screen for risks: She recommends medical assessment and lab work before fasting, especially for people with health concerns. She says fasting should not replace conventional cancer treatment and is not suitable for everyone. Serious cardiovascular or excretory-organ disease, significant depression or panic disorder, and pregnancy are among the reasons she gives for caution or avoidance. Decisions should be made individually with a clinician.
• Do not apply adult fasting advice to children: She says she does not recommend fasting in her pediatric practice, while noting that a separate supervised lifestyle program is used for children with overweight.

The guest also describes fasting as potentially triggering processes such as autophagy and changes in metabolism. These are presented as her explanations of fasting’s effects, rather than as independently verified conclusions in the conversation.
