Abstract

SANCHEZ, S.  and  BARRAGAN, J.. Metabolically active weight: between Kleiber's law and the second law of thermodinamics. Rev. argent. endocrinol. metab. [online]. 2011, vol.48, n.3, pp.136-142. ISSN 1851-3034.

In arguing that living things use their dissipated energy to generate their own structure, the Margalef principle relates metabolic capacity to body mass. By studying the Basal Metabolic Rate (BMR) and body weight we can observe the proposed relationship. The ability to dissipate energy contributes to a growing structure and declines over time. In this context, the accuracy of the concept of metabolically active weight is fundamental. The dynamics of the relationship between these two variables may contribute to an understanding of fundamental aspects of living organisms. In addition, a proper definition of the metabolically active weight may influence the clinical aspects of this relationships.

Keywords : Body mass; Basal metabolism; Kleiber's law; Second law of Thermodynamics.
