Why is leptin not clinically useful in treating obesity?

• It causes severe side effects

• It cannot be administered orally

• It is too expensive to produce

• Obese individuals are insensitive to leptin

What is necessary for leptin to exert its anorexigenic functions?

• It must cross the blood-brain barrier

• It must be taken with food

• It must be administered intravenously

• It must be combined with other hormones

What is unclear about leptin's role in obesity treatment?

• Its production in the body
