We also engage in the activities other than "eating, drinking and sleeping". If our activities involved only that then how can we experience pleasure in life? Philosophically characteristics of sat, chit and ananda can be explained like this :
Sat (સત્ ) ----------------- Substance, Inanimate, Physical
Chit (ચિત્) ----------------- Prana-consciousness, Subtle
Ananda (આનંદ) ----------- Mind and behind it Hradayam (હ્રદયમ)
Here mind means it's purified form.
We desire to perform good deeds. There is interest in somebodies wellness. We feel it is good to be helpful to somebody. We develop compassion towards people who have practiced this kind of good wishes, good deeds and its spirit in their lives. Occasionally we also enter the ananda that is different from ananda of physical stuff. It means every element has different characteristics and nature.

My two cents: Wikipedia has an excellent explanation of the word "Satchitanand".
