Which factor most influences daily energy needs after calculating RER?

Explanation:
After you’ve calculated RER, daily energy needs are determined by multiplying that resting requirement by a factor that reflects how much energy the animal actually uses in daily life. The biggest influence is activity level and life stage: a more active animal or one that is growing, pregnant, or lactating has higher energy needs, while a sedentary adult has lower needs. Coat color, eye color, and fur length don’t directly change caloric requirements in the standard calculation, so they don’t drive the adjustment from RER to daily energy needs.
