Our armchair endo opines:
""Having too much fat --> more leptin --> less hunger --> bad.
less leptin --> more hunger --> good."
What is the source of leptin? What is its role in energy metabolism?
What other major hormone is closely related to its function? What is
the other hormones source?
Careful now as you answer, self contridiction alert.
Failure to answer is confession of self contridiction.
God bless.
