Final answer:
An energy imbalance, in the form of excess or deficient caloric intake, primarily impacts weight and waist circumference. This is because weight change reflects an energy surplus or deficit, and waist circumference is a measure of abdominal fat which varies with caloric intake.
Step-by-step explanation:
Physical measurements can indeed be influenced by an energy imbalance in the body. Energy imbalances, whether they be an excess or deficiency of energy (caloric) intake, impact measurements related to body mass and fat distribution. Thus, option D) 'Weight and waist circumference' would be most influenced by an energy imbalance. This is because weight gain or loss directly reflects an energy surplus or deficit, respectively. Meanwhile, waist circumference is a measure of abdominal fat, which can increase with excessive caloric intake and decrease with caloric restriction.
