Fasting diets carry several contraindications tied to personal health and daily demands. Ksenia Selezneva, a nutritionist and head of the dietetics department at the European Medical Center, notes that suitability varies from person to person and should be discussed with a healthcare professional before starting any fasting plan.
The central precaution is intolerance to any component of the fasting regimen. For instance, someone with lactose intolerance should avoid fermented milk fasting days, as this could trigger uncomfortable symptoms or complications. When there are flare-ups of gastrointestinal conditions, diabetes, pregnancy, or breastfeeding, it is essential to seek medical advice. A qualified clinician can help determine whether a specific fasting day offers potential benefits or if it would be wiser to skip it. Selezneva also stresses that fasting is not appropriate during periods of heightened physical or mental activity, which can amplify stress on the body and reduce performance or well-being.
Different fasting options may not be suitable for individuals with certain health issues. For example, days focused on fruit or vegetables can increase stomach acidity, potentially aggravating gastritis or ulcers. Fruit-based mono-diet approaches should be approached with caution in people with elevated blood sugar levels, as they can affect glucose control and energy stability.
Experts often encourage patients to experiment with various fasting day concepts to discover what works best for them. Some people may feel energized by a fresh or baked apple paired with ample water, while others may find the same option tedious and unsustainable. The goal is to identify a plan that integrates smoothly with personal health, daily routines, and long-term wellness goals. A thoughtful approach allows individuals to balance nourishment with rest and activity, rather than pursuing fasting as a one-size-fits-all solution. Collaboration with a healthcare professional helps tailor a regimen that aligns with medical history, current medications, and lifestyle needs.
All reflections on fasting days should consider the whole person, including metabolic responses, hydration status, and emotional well-being. If any adverse symptoms arise, it is prudent to reassess, pause, or modify the plan under medical supervision. This careful, personalized approach ensures that fasting practices support health and daily functioning rather than compromising them. (Selezneva, EMC)
