What role does Triglyceride senken play in fatigue?

Lowering triglycerides is often linked to improved metabolic health, which may indirectly reduce fatigue – for example through better insulin sensitivity or lower inflammation. However, direct evidence for a causal role of triglyceride reduction in fatigue is weak. Fatigue has many causes (sleep, stress, iron deficiency, thyroid, etc.), and triglycerides are just one piece. Aggressive lowering via extreme diets or medications can even promote fatigue (e.g., calorie restriction). Evidence: mixed, mostly mechanistic. Caveat: Not a substitute for medical evaluation of persistent fatigue.
