Calories are a fundamental unit of energy derived from food and are essential for the maintenance, growth, and repair of all body systems, including the structural system, which comprises bones, muscles, tendons, and connective tissues. Scientific evidence robustly supports the necessity of adequate caloric intake to sustain the metabolic processes required for the synthesis and maintenance of structural components. For example, insufficient caloric intake is associated with decreased bone mineral density, muscle wasting, and impaired connective tissue repair, as demonstrated in numerous clinical and epidemiological studies.

Research has shown that chronic energy deficiency can lead to conditions such as osteoporosis and sarcopenia, particularly in populations with high energy expenditure or restricted diets. Calories, when consumed in appropriate amounts, provide the energy required for the anabolic processes that underlie growth and maintenance of the structural system. Furthermore, caloric intake is critical for the absorption and utilization of key nutrients (such as protein, calcium, and vitamin D) that directly support bone and muscle health. Therefore, the use of calories to support the structural system is strongly grounded in scientific evidence, reflecting a direct relationship between energy availability and the integrity of the body's structural components.
