warum nehme ich immer mehr zu — what symptoms are typical?

The question about typical symptoms of unexplained weight gain is complex because causes are multifactorial. Common symptoms include persistent fatigue, reduced energy, cravings (especially for sweets), water retention, digestive issues like bloating or constipation, and mood swings. Underlying factors often involve hypothyroidism (lowering basal metabolic rate), elevated cortisol from chronic stress (promoting abdominal fat), gut microbiome imbalances (dysbiosis) affecting nutrient absorption and appetite, poor sleep, certain medications, and high-calorie diets. It is important to note that consumer DNA tests or metabolism analyses offered by MyBody-X can identify single risk variants (e.g., SNPs with small effects on metabolism), but a 'slow metabolism' claim based solely on genetics is not clinically reliable. Evidence for lifespan extension from such tests is weak (GWAS/mechanistic, not interventional). Standard clinical risk factors (thyroid function, blood glucose, inflammatory markers) are far more actionable. If you experience persistent weight gain, consult a clinician to rule out organic causes before relying on direct-to-consumer tests.
