Feeding behavior can also resemble a servo-
control mechanism
• Animals tend to adjust
their food intake to
achieve a normal body
weight.
• Curve b = control rats on
a normal diet.
• Curve a = rats force fed
for 15 days.
• Curve c = rats on a
restricted diet for 15 days.
• All rats returned to their
normal body weight after
either force feeding or
restriction.
