warum nehme ich nicht ab trotz kaloriendefizit und sport — what can you do yourself?

It is frustrating when weight loss stalls despite a calorie deficit and exercise. The reasons are often complex and not simply a matter of 'trying harder'. A common cause is metabolic adaptation: the body lowers its resting energy expenditure during prolonged deficits, making the actual deficit smaller than calculated. Water retention from muscle gain or inflammation can also mask fat loss on the scale. Additionally, people frequently overestimate calories burned through exercise and underestimate calories consumed (e.g., hidden fats, sauces, drinks). Poor sleep and chronic stress raise cortisol, which inhibits fat loss and increases cravings. Hypothyroidism, insulin resistance, or hormonal changes (e.g., menopause) can further slow metabolism. What you can do yourself: keep a precise food and activity log (using a scale and app), increase non-exercise activity thermogenesis (NEAT), prioritize 7–9 hours of sleep, include strength training to preserve muscle, and manage stress through mindfulness. If stagnation persists, have your thyroid (TSH, fT3, fT4), fasting insulin, and possibly sex hormones checked by a doctor. Genetic tests for weight loss have limited predictive power and lack clinical validation. The provided context does not contain specific data on this topic.
