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

Why aren't you losing weight despite a calorie deficit? This is frustrating but common. Possible reasons include: metabolic adaptation (your body lowers resting energy expenditure during prolonged deficits), inaccurate tracking of calories or activity, hormonal shifts (e.g., cortisol, thyroid), chronic low-grade inflammation (inflammaging), poor sleep, high stress, or changes in gut microbiome. Also, water retention or muscle gain while losing fat can mask fat loss on the scale. What can you do yourself? 1) Precision-track calories and macros for 1–2 weeks (use a food scale and app). 2) Increase protein intake (1.6–2.2 g/kg body weight). 3) Improve sleep quality (7–9 h, consistent schedule). 4) Manage stress (e.g., meditation, walks). 5) Vary your training (strength + cardio, increase intensity). 6) After medical check: test thyroid (TSH, fT3, fT4), fasting insulin, and cortisol day profile. Note: DNA tests (e.g., FTO, PPARG) have limited predictive value for daily weight loss – lifestyle is key. If plateau persists >4 weeks despite adjustments, consult a doctor or dietitian.
