welche stoffwechseltypen gibt es — which blood markers matter?

The concept of 'metabolic types' is popular in wellness culture but lacks strong scientific validation. Categories like ectomorph, mesomorph, endomorph originate from body morphology, not metabolism. Similarly, 'carb type' or 'protein type' are marketing constructs. Evidence-based metabolic assessment relies on blood markers: fasting glucose, HbA1c, and insulin (HOMA-IR) reflect insulin sensitivity. Thyroid markers (TSH, fT3, fT4) influence basal metabolic rate. A lipid panel (total, LDL, HDL cholesterol, triglycerides) indicates lipid metabolism. Liver enzymes (ALT, GGT) and uric acid are also informative. MyBody-X offers such blood tests, but results require clinical interpretation. Single values are snapshots; longitudinal monitoring and medical context are essential. Evidence: human-strong for listed markers; 'metabolic types' are marketing. Be cautious of overblown claims.
