Question 3 of 7
Why do we get hungry?
-
Habit helps, but you can be ravenous well before lunch.
-
A tummy gurgles when it is empty *and* when it is full.
-
So the brain sends a “time to eat” signal. Eat, and the signal stops.
-
A smell can make you keener; it is not what starts the hunger.

Why do we like sweet things?

The liking comes first, long before anyone teaches anything.
