welche stoffwechseltypen gibt es — what symptoms are typical?

The concept of 'metabolism types' is popular in diet and fitness marketing but lacks a standardized scientific definition. Companies like MyBody-X may categorize individuals based on genetic variants (e.g., FTO, PPARG, TCF7L2) into types such as 'carb-sensitive', 'fat-sensitive', or 'mixed'. Typical symptoms associated with these types include: for carb-sensitive – cravings, blood sugar swings, post-meal fatigue, and weight gain; for fat-sensitive – bloating, digestive discomfort, or low energy after fatty meals. However, these categories are not clinically validated and should not be used for medical diagnosis. Individual metabolic responses are influenced by many factors (gut microbiome, hormones, lifestyle). MyBody-X tests offer personalized dietary suggestions but are not diagnostic. Any symptoms should be evaluated by a healthcare professional.
