2
Q
What is the function of leptin?
A
Appetite regulation - suppresses food intake and increases basal metabolic rate
3
Q
How is leptin resistance implicated in obesity?
A
Down-regulation of leptin receptors may cause decreased effectiveness, reducing appetite supression cues and decreasing metabolic rate.
4
Q

A
They are likely resistant to the effects of leptin - therefore they produce excess to compensate
