Calorie Restriction

[CrazyGmatter]

Calorie restriction, a diet high in nutrients but low in calories, is known to prolong the life of rats and mice by preventing heart disease, cancer, diabetes, and other diseases. A six-month study of 48 moderately overweight people, who each reduced their calorie intake by at least 25 percent, demonstrated decreases in insulin levels and body temperature, with the greatest decrease observed in individuals with the greatest percentage change in their calorie intake. Low insulin level and body temperature are both considered signs of longevity, partly because an earlier study by other researchers found both traits in long-lived people.

If the above statements are true, they support which of the following inferences?
1.Calorie restriction produces similar results in humans as it does in rats and mice.
2.Humans who reduce their calorie intake by at least 25 percent on a long-term basis will
live longer than they would have had they not done so.
3.Calorie intake is directly correlated to insulin level in moderately overweight individuals.
4.Individuals with low insulin levels are healthier than individuals with high insulin levels.
5.Some individuals in the study reduced their calorie intake by more than 25 percent.

1.Calorie restriction produces similar results in humans as it does in rats and mice. - incorrect
2.Humans who reduce their calorie intake by at least 25 percent on a long-term basis will - scope is only Moderate OW people
live longer than they would have had they not done so.
3.Calorie intake is directly correlated to insulin level in moderately overweight individuals.
4.Individuals with low insulin levels are healthier than individuals with high insulin levels.
5.Some individuals in the study reduced their calorie intake by more than 25 percent. This is correct ( reduced calorie intake atleast 25 )

1 - Reject as it talks about moderately overweight individuals and not humans as such
2 - This is probably as per the last sentence; 'Will' is a strong word. Also long term if more than a year we cant say. Argument mentions only 6 months.
3- It is indirectly co-related
4 - It talks about longevity and not about being healthier
5 - Says atleast 25% with the greatest decrease in individuals with the greatest percentage change in calorie intake.

IMO - 5

[sushkan2008]

I think its 4

[anurag]

IMO 5.

3 - There is no evidence to prove higher calorie intake will increase insulin levels; it's the other way around.

Official Answer is E..

Thanks for the explaination guys...
