Statement a. is false as Ghrelin increases appetite and high ghrelin levels are seen before meals during hunger and lower levels are seen after mealtimes. It is also known as hunger hormone.

Statement c. is false as body responds to reduced calorie intake by decreasing the metabolic rate.

Statement d. is false as leptin is a hormone secreted by adipocytes and it inhibits hunger. Hence, absence of leptin or its resistance leads to excessive food intake and weight gain.
