What does the term 'set point' refer to in obesity?

• A. A proposed regulated weight level the body defends via physiological mechanisms
• B. A fixed BMI value
• C. A maximum weight allowed
• D. A recommended weight loss target

Answer: (A)

Set point refers to a regulated weight level that the body defends through physiological mechanisms. The brain uses hormonal signals from fat tissue and other nutrients to adjust hunger, appetite, and energy expenditure so that when weight drifts away from this level, the body pushes back toward it. If you lose weight, hunger tends to increase and metabolism can slow, making it easier to regain weight. This helps explain why weight loss is often followed by regain and why long-term obesity management usually needs strategies that address these biological regulators, not just calorie counting. It isn’t a fixed BMI value, a maximum weight, or a suggested target weight; it’s a defended weight that can shift with genetics, hormones, and the environment.
