BOOKMARKED
Researchers have found that when very overweight people, who tend to have relatively low metabolic rates, lose weight primarily through dieting, their metabolism 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: Reseachers 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.

Negate A, the conclusion fails: If newly thin people consumed less calories, it will be hard to argue that they will regain their weight.

I feel C weakens the conclusion.....


TeHCM you got it ......OA is A

(A) stands. Whose to say that such people don`t need to eat so much because they had a gastric bypass or some similiar operation?

I say A b/c if this were true then overweight people would not regain the weight. This eliminates that possibility and fixes a flaw in the conclusion.

A, for the same reason.

Conclusion is that people will gain weight back. A supports that

Re: CR : Researchers have found that when very overweight people [#permalink] New post 11 Feb 2009, 21:17
My ans is A.
The argument claims that overweight people who lost wiight thru deiting will regain weight bcos their metabolim rate does not vary. This clearly assumes that most of the overweight ppl tend to consume substrantially more calories and hence tehre are relatively few overweight ppl who tend to consume less calerories

Re: CR : Researchers have found that when very overweight people [#permalink] New post 12 Feb 2009, 02:29
I will go with A...

Explanation. As the option states (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.

it means that the overweight people who have dieted will discontinue to eat fewer calories, and there metabolic rates are also slow so the body will regain the weight untill their body size matches the metabolic rate..

Can someone explain why its not C?


You should find the scope of the argument and compare the scope to the meaning that C suggests. How to weigh or determin the amount of calories IS NOT a focus of argument, C out

Premise:
Calori burned (weight reduced person) , metabolic rate < calori burned (normal person ) , metabolic rate
over weight person - less food - less metabolic rate - less calori - normal weight

Conclusion:
Less weight person -more food -more metabolic rate - more cakori - normal weight

My Ans - C)

I pick (C)

premise says ==> overly weight people who tend to have relatively low metabolic rates, lose weight primarily through dieting, their metabolisms generally remain unchanged.

assumption ==> The amount of calories that a person usually burns in a day (low metabolism) is determined more by the amount that is consumed that day (dieting) than by the current weight of the individual.
