warum nehme ich zu trotz kaloriendefizit — what can you do yourself?

The question of why one gains weight despite a calorie deficit is not directly addressed in the provided contexts. In general medical practice, possible reasons include inaccurate calorie tracking (underreporting intake or overestimating expenditure), water retention (due to sodium, carbohydrates, or hormonal cycles), metabolic adaptation (the body lowers energy expenditure in response to prolonged restriction), hormonal imbalances (thyroid, cortisol, insulin), or side effects of medications. What you can do yourself: keep a precise food diary with a scale, use a reliable app to track calories, ensure you account for all liquids and cooking oils, prioritize protein and fiber to maintain satiety, manage stress, get adequate sleep, and if the problem persists, consult a doctor to rule out medical causes. Consumer DNA tests or microbiome analyses are not validated for diagnosing weight gain causes; the evidence is weak and not actionable. The provided knowledge snippets emphasize that such tests often lack clinical utility for metabolic issues. Therefore, a conservative, evidence-aware approach is recommended.
