Allostatic load and resource availability are fundamentally linked as they are measured in the same units [1] and define the threshold for allostatic overload [2]. Furthermore, their mathematical difference determines the perturbation resistance potential [3] and the perceived resource potential [4].

formulaPerturbation resistance potential (PRP) is calculated as Eg – (Ee + Ei), representing the difference between allostatic load and resource availability.
claimThe Perceived Resource Potential (PRP) describes the gap between allostatic load (Eload) and resource availability (Ecr), and is proposed to correlate with glucocorticoid levels rather than allostatic load itself.
formulaAllostatic overload Type 1 occurs when an animal is in a negative energy balance, specifically when the sum of all types of allostatic load exceeds resource availability (Eg).
formulaResource availability (Eg) represents a limit to the energy an animal can expend without entering a negative energy balance and must be measured in the same units as allostatic load.
