What increases the metabolic rate to the greatest extent?
A) increased skeletal muscle activity
B) increased mental effort
C) increased dietary fibre intake
D) increased brown fat deposition

Question

Quizplus · Accepted Answer

Increased skeletal muscle activity leads to an increase in basal metabolic rate (BMR) as skeletal muscles require energy for contraction and maintenance. This increase in BMR can last for several hours after exercise, leading to a greater overall increase in metabolic rate compared to the other options listed. Contrarily, options B and C have a negligible effect on BMR, and while brown fat deposition is associated with increased metabolic rate, it is not necessarily the greatest extent.
