Researchers have found that when very overweight people, who tend to have
relatively low metabolic rates, lose weight primarily through dieting, their
metabolisms generally remain unchanged. They will thus burn significantly
fewer calories at the new weight than do people whose weight is normally at
that level. Such newly thin persons will, therefore, ultimately regain
weight until their body size again matches their metabolic rate.
The conclusion of the argument above depends on which of the following
assumptions?
(A) Relatively few very overweight people who have dieted down to a new
weight tend to continue to consume substantially fewer calories than do
people whose normal weight is at that level.
(B) The metabolisms of people who are usually not overweight are much more
able to vary than the metabolisms of people who have been very overweight.
(C) The amount of calories that a person usually burns in a day is determined
more by the amount that is consumed that day than by the current weight of
the individual.
(D) Researchers have not yet determined whether the metabolic rates of
formerly very overweight individuals can be accelerated by means of chemical
agents.
(E) Because of the constancy of their metabolic rates, people who are at
their usual weight normally have as much difficulty gaining weight as they do
losing it.
