was kurbelt die fettverbrennung an — which blood markers matter?

Fat burning is influenced by factors like exercise, diet, and hormones. Key blood markers include: fasting triglycerides (elevated levels indicate reduced fat burning), free fatty acids (reflect mobilization of fat stores), ketones (like beta-hydroxybutyrate, a marker of ketosis), insulin (low levels promote fat burning), and glucose (stable levels favor fat utilization). Thyroid hormones (fT3, fT4) and adiponectin also play roles. The evidence is human-moderate: clear associations exist, but individual variability is high. No single marker is sufficient; a combination of lab values and lifestyle assessment is more reliable. Be cautious of exaggerated claims from supplements or diets based on only one marker.
