Nutrient Partitioning Hormones

Meaning

Nutrient Partitioning Hormones are a class of endocrine messengers that regulate the distribution and allocation of ingested macronutrients (carbohydrates, fats, and proteins) to various tissues for storage, utilization, or structural repair. Key examples include insulin, glucagon, cortisol, and growth hormone, which collectively orchestrate whether energy substrates are shunted toward adipose tissue storage or muscle tissue uptake. Optimal function of these hormones is essential for maintaining a healthy body composition, metabolic flexibility, and preventing insulin resistance. Dysregulation in this partitioning is a core feature of metabolic syndrome.
