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.

A, for the same reason.

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

C? Will explain if correct.

I get A.

Premise: Overweight people who lose weight from dieting keep the same metabolism
Premise: They will burn less calories at the new lower weight than people who are normally at that weight.
---------------------------------------------------------------------------------------------------------
Conclusion: These people will regain weight until their body size matches their unchanged metabolism.

In order to reach that conclusion there is one premise (assumption) that we need. If the people are who lose weight by dieting will eventually regain weight than we HAVE to assume that they will stop dieting. Because if they continue to consume the same calories that they did to lose weight then they will not gain any of it back.

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

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..

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

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.

Can some explain how to tackle assumption efficiently...thanks

The conclusion of the argument above depends on which of the following assumptions?

Conclusion - Newly thin people regain weight.

Possible assumptions - Newly thin people start eating more. or
The metabolism of newly thin people further slows down thereby not burning calories,leading to increased weight.

(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. - Hold

(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. - Para is Talking about overweight people. Out of scope.

(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. - Out of scope.

(D) Researchers have not yet determined whether the metabolic rates of formerly very overweight individuals can be accelerated by means of chemical agents. - Out of scope.

(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. - Hold

Can some explain how to tackle assumption efficiently...thanks

Now between A and E use negation and see its effect of conclusion.Negation should undermine the conclusion.

E Not Because of the constancy of their metabolic rates, people who are at their usual weight normally do not have as much difficulty gaining weight as they do losing it. - Dosen't effect the conclusion at all.

A No very overweight people who have dieted down to a new weight tended to continue to consume substantially more calories than do people whose weight is at that level." - If this is true then how Newly thin people regained weight ? Hence this undermines the conclusion.

Hence A prevails.

Amit has pretty much covered all the ground. Let me just add here that an assumption is a missing premise that is necessary for the conclusion to be true. The assumption has to be true for the conclusion to be true. Hence if you are lost between 2-3 choices, negate each choice. Once you negate an option, if your conclusion can still be true, it means the option is not an assumption. It is a very useful trick.

I found this question in another topic, but the explanation is still unclear to me. So, I want to make new thread to open more discussion on this problem. OA later.

I went with A. By the statements, if one loses weight and he does not continue to be on the diet then he ll gain weight. Meaning people who are already on that weight size will consume more than he does
