What are the four key facts of weight regulation? (in terms of set point)
What will be an ideal response?
(1) body weight remains relatively constant in many adults; however, constant body weight does not require, or even imply, a set point
(2) many adults experience enduring changes in body weight; the fact that many adults experience long-term changes in body weight is a strong argument against the set point model
(3) if a person's intake of food is reduced, metabolic changes that limit the loss of weight occur; the opposite happens when the subject overeats (although this refutes set point theory, settling theory accounts for it)
(4) after an individual has lost a substantial amount of weight (by dieting, exercise, or the surgical removal of fat), there is a tendency for the original weight to be regained once he or she returns to the previous eating and energy related lifestyle
