Verified step by step guidance

1. Step 1: Understand the relationship between blood glucose levels and hunger. Blood glucose levels are a key indicator of energy availability in the body. When blood glucose levels are low, the body signals hunger to encourage food intake and restore energy balance.
2. Step 2: Learn about the role of the hypothalamus in hunger regulation. The hypothalamus monitors blood glucose levels and triggers hunger signals when levels drop below a certain threshold.
3. Step 3: Recognize the physiological response to rising blood glucose levels. As blood glucose levels increase, the hypothalamus detects the change and reduces hunger signals because the body has sufficient energy.
4. Step 4: Eliminate incorrect options based on the physiological mechanism. For example, 'The sensation of hunger increases' is incorrect because rising glucose levels suppress hunger. Similarly, 'The sensation of hunger remains unchanged' and 'The sensation of hunger fluctuates unpredictably' do not align with the predictable response of the hypothalamus.
5. Step 5: Conclude that the correct answer is 'The sensation of hunger decreases,' as this aligns with the body's mechanism to regulate energy intake based on blood glucose levels.
