MY FOODBOOK + Diätplan: when to see a doctor?

MyFoodBook and its associated diet plan are lifestyle tools, not medical diagnostics or therapy. You should see a doctor before starting any diet plan if you have chronic conditions (e.g., diabetes, cardiovascular disease, thyroid disorders), take medications (especially blood thinners, insulin, diuretics), or experience unexplained symptoms like fatigue, weight loss, or digestive issues. Pregnancy, breastfeeding, or a history of eating disorders also require medical guidance. MyFoodBook uses genetic and metabolic data to provide personalized suggestions, but these do not replace clinical diagnosis. The evidence for personalized diet plans from genetic tests is mostly mechanistic or marketing-driven; robust randomized controlled trials with hard endpoints are often lacking. A doctor can check relevant blood markers (e.g., iron, vitamin D, thyroid hormones) and provide a comprehensive risk assessment. If you notice unusual symptoms while following the plan, seek medical advice promptly.
