What should I know about welche stoffwechseltypen gibt es?

The concept of 'metabolic types' (e.g., carbohydrate, protein, or mixed types) is popular in alternative nutrition but lacks strong scientific evidence. Most typing systems are based on oversimplified ideas and are not supported by robust clinical studies. Human metabolism is highly individual, influenced by genetics, hormones, gut microbiome, diet, activity, and sleep. While DNA tests can identify small-effect variants (e.g., in FTO or MC4R), these do not reliably classify someone into a distinct metabolic type. MyBody-X offers hormone, nutrient, and DNA analyses, but direct metabolic typing is not evidence-based. A balanced diet rich in vegetables, whole grains, healthy fats, and adequate protein, combined with regular exercise, remains the most effective strategy. Supplements or restrictive diets should only be used when a deficiency is confirmed or under medical guidance. Be cautious of marketing claims that promise a 'perfect metabolic type' – the reality is far more nuanced.
