The 'weight thermostat' concept is best described by which term?

• A. The need to establish relationships.
• B. The drive to eat due to hunger.
• C. The hormone that signals fullness.
• D. The point at which weight thermostat is set.

Answer: (D)

This concept is about the body's regulation of weight around a stable level, like a thermostat that keeps you near a set point. The body uses signals from hormones and metabolism to push appetite up or down and adjust energy use so weight tends to return to that target level when it shifts. That makes the best description the point at which the weight thermostat is set—the set point. The other ideas describe processes related to hunger, social needs, or a single hormone, but they don’t name the regulatory target that the body defends through changes in intake and expenditure.
