Figure 1.
Compartmental models of body composition. From left to right the columns represent a 6 compartment model, a 2 compartment model, a 3 compartment model and a 4 compartment model. ICF = intracellular fluid, P = protein, G = glucose + glycogen, ECF = extracellular fluid, M = mineral mass, FFM = fat free mass. For each model, fat is represented as 25% of weight. Mineral is 4% in the 3, 4 and 6 compartment model. Protein is 22%.
