Leptin Resistance Is a Condition

Leptin resistance is a condition:

A) in which a person who is obese has high blood levels of leptin, but this does not produce decreased food intake and increased BMR.
B) in which a person who is severely underweight and has high blood levels of leptin will refuse to eat.
C) that runs in families and is characterized by abnormally low levels of leptin.
D) in which lower-than-normal blood levels of leptin reduces eating behavior and increases BMR.
