Okpomoku pụrụ iche, okpomoku ezi uche, na okpomoku latent bụ nha anụ ahụ:
Ndị okpomọkụ a kapịrị ọnụ nke ihe bụ oke okpomọkụ a ga -enyerịrị ya n'otu nkeji nke ihe ahụ iji bulie okpomoku ya otu otu. Ọnụ ego ahụ na -agbanwe nke ukwuu dabere na ọnọdụ ihe dị n'ime ya tupu etinye ya ọkụ. Dịka ọmụmaatụ, ọ na -ewe otu kalori ka ọ mụbaa mmiri na ụlọ okpomọkụ site n'otu nrịgo, mana ọ na -ewe naanị kalori 0,5 iji mee ka okpomoku kpụ ọkụ n'ọnụ ruo -5 n'ogo. Okpomọkụ dị iche iche na -adaberekwa na nrụgide ikuku. Otu ihe ahụ na mgbada ikuku dị ala nwere obere okpomọkụ akọwapụtara nke ọma.
