The relationship between modern environments and metabolic health has been widely examined in physiology, epidemiology, and public health. A substantial body of evidence links reduced physical activity, thermal stability, and chronic stress to adverse metabolic outcomes, including visceral adiposity, insulin resistance, and pre-diabetic states. This paper does not seek to replace those established findings. Rather, it offers a complementary systems-oriented interpretation, applying concepts from network science, systems engineering, and environmental design to the question of how constrained environments influence metabolic regulation. Written from the perspective of a Chief Technology Officer experienced in the design and analysis of distributed systems, the paper argues that human physiology may usefully be understood as a dynamic network dependent on flow, variability, and adaptive interaction with its surroundings. The central metaphor—“you can’t wear a skirt on the moon… or can you?”—is used not as a literal claim, but as a conceptual contrast between low-constraint environments, in which movement, thermal exchange, and behavioural autonomy are preserved, and highly constrained environments, in which these interactions are externally mediated. Across seven sections, the paper examines three principal pathways through which constrained environments may influence metabolic health: mechanical restriction of movement, suppression of thermal variability, and chronic activation of stress pathways. It further argues that modern terrestrial environments, and emerging AI- driven future systems, increasingly reproduce these constraints in attenuated but cumulative forms. The likely consequence is a shift in physiological behaviour toward reduced metabolic throughput, diminished adaptive flexibility, and increased visceral fat storage. The contribution of this paper lies in interpretation and integration rather than in primary biomedical discovery. By combining established biological literature with a systems framework, it proposes that metabolic dysfunction cannot be fully understood without considering the architecture of the environments in which human beings now live. The paper concludes that the prevention of visceral adiposity and related metabolic disease requires not only behavioural advice, but also deliberate design of environments that restore movement, variability, and autonomy.
