Question

practice it
belief that brain mechanisms regulate body weight around a genetically predetermined \set point\
metabolic rate theory
set point theory
heat dissipation theory
air pressure theory
pulse rate theory

Explanation:

The set point theory posits that the body has a genetically determined weight range (set point) and brain mechanisms work to keep body weight within this range. Metabolic rate theory focuses on the rate of energy expenditure. Heat dissipation theory is about heat loss. Air pressure theory relates to air pressure effects. Pulse rate theory is about heart - beat rate. Since the description in the problem is about body weight regulation around a set point, set point theory is the correct match.

Answer:

set point theory
