摘要

Humans possess two primary types of adipose tissue: white and brown. Under certain conditions, such as cold exposure, white adipose depots can remodel into metabolically active beige adipocytes through a process known as “browning.” Functional brown adipose tissue (BAT) persists in adults and contributes to systemic energy expenditure via uncoupling protein-1 (UCP-1) mediated thermogenesis. Beyond energy storage, adipose tissue acts as a dynamic endocrine organ regulating inflammation and metabolism. Energy restriction not only promotes fat loss but also drives favorable adipose tissue remodeling, reduces low-grade inflammation, and improves metabolic flexibility. This review synthesizes current evidence on the effects of energy restriction on adipose tissue phenotype and function, emphasizing browning, thermogenesis, adipokine secretion, and inflammatory modulation. Findings from recent studies indicate that energy restriction induces beige adipocyte formation, upregulates thermogenic markers such as UCP-1, improves adipokine profiles, and attenuates inflammatory responses. These adaptations enhance energy expenditure and metabolic flexibility, highlighting adipose tissue as a key mediator of the systemic benefits of caloric restriction. Overall, energy restriction emerges as a promising intervention to remodel adipose tissue, shift it toward a metabolically active and anti-inflammatory state, and improve overall metabolic health.
