Help me Escape from this Cereal Box

Imagining life as a giant,
I find the hardest part,
to be eating enough,
burning calories chasing,
small morsels around,
only to find your strength,
thinning like melting ice.

Next time,
I will be,
cautious,
to stay,
my mouth,
from feeding,
before I,
heed the food,
pyramid.
