wie viel eiweiß brauche ich — what symptoms are typical?

The question about protein requirements and typical symptoms is evidence-based but highly context-dependent. For healthy adults, general guidelines recommend 0.8 g protein per kg body weight (DGE, WHO). Athletes, elderly, or those in specific life stages (pregnancy, illness) may need 1.2–2.0 g/kg. Typical deficiency symptoms include muscle wasting, fatigue, poor wound healing, edema, and weakened immunity. Excess protein (especially >2 g/kg long-term) can cause digestive issues, increased kidney strain (in those with pre-existing conditions), and possible dehydration. The provided context lacks direct data on protein needs or symptoms; answers rely on established practice guidelines. Caveat: Direct-to-consumer genetic tests for protein-related genes (e.g., FADS, PPARA) are usually insufficient to derive personalized protein recommendations. Blood markers (e.g., albumin, urea) and dietary assessment are more reliable than genotype interpretation alone.
