-The Weight Regulating Mechanism (WRM) is a feature of the hypothalamus of the brain that controls how much the body should weigh.
-The WRM has a setpoint for controlling both appetite and the amount of fat stored.
-A very low-calorie diet will trigger the body to adjust its setpoint to a reduced basal metabolic rate (BMR – lowest level of caloric intake to sustain life) .
Body's fat thermostat
