Power, P = 100 W = 100 J/s

Time in one day, t = 24 hr (60 min/1 hr)(60s/1min) = 86400 s

In an average human, basic life processes require energy to be supplied at a steady rate of 100 W.

What daily energy intake, in Calories, is required to maintain these basic processes? This is the minimum daily caloric intake needed to avoid starvation.
