Some researchers support the idea that obesity is related to genetics. They indicate that in the distant past, people with genes like FTO enabled them to store energy as fat between times of famine. Unfortunately, in the modern world, these same genes prepare bodies with fat storage for famines that will never come.

This perspective of obesity is best aligned with the ideas of

a.evolutionary theory.

b.psychoanalytic theory.

c.behaviorism.

d.structuralism.
