Adaptive thermogenesis is another name for which phenomenon observed after weight loss?

• A. Leptin resistance
• B. Increased appetite
• C. Metabolic adaptation
• D. Insulin resistance

Answer: (C)

Adaptive thermogenesis describes the body's adjustment of energy expenditure in response to weight loss, where the resting metabolic rate falls more than would be expected from the loss of body mass alone. This metabolic adaptation is driven by hormonal and neural signals—such as lower leptin levels and shifts in thyroid hormone activity—that signal the body to conserve energy. The result is slower weight loss over time and a higher risk of weight regain. This process is distinct from changes in appetite or insulin sensitivity; it specifically refers to the energy-burning side of weight balance that occurs after losing weight.
