Troy finds it very hard to lose weight, and his doctor suggests this may be due to a deficiency of the hormone leptin. Which of the following symptoms might lead Troy's doctor to this conclusion? Troy continues to feel hungry even after eating a big meal. Troy has a high level of glucose in his blood. Troy has no appetite but is still having trouble losing weight. Food tastes unusually sweet to Troy.

Troy continues to feel hungry even after eating a big meal.

After you finish a big meal, the level of glucose in your bloodstream increases. What happens next in order for your body to process the glucose? When glucose reaches a certain level, your hypothalamus stops producing it. Your pancreas produces insulin to manage the glucose. Your stomach releases ghrelin to counteract the glucose. Your fat cells release leptin, which tells your hypothalamus to stop producing glucose.

Your pancreas produces insulin to manage the glucose.
