Multiple Choice Question When people are sleep deprived, leptin levels are 20 to 30 percent __ while ghrelin levels can be 20 to 30 percent __ higher; higher lower; lower higher; lower lower; higher

The correct answer is **lower; higher**.<br /><br />When sleep-deprived, leptin (a hormone that signals satiety) decreases, making you feel hungrier. At the same time, ghrelin (a hormone that stimulates appetite) increases, further contributing to increased hunger. Therefore, leptin goes down (lower) and ghrelin goes up (higher).<br />
