Question 1
At baseline the participants with a higher BMI were those in the highest quartile for animal protein, however, the BMI for all participants at baseline was not severely overweight or obese (25.5+/-3.1) Does this number change your opinion or thoughts on the study at all? if so, how?

Considering the year it took place, no it doesn't. People lived different lives then without the overload of simplicities that we live with today. However I would like to see it done again today where it can show more impact on a much more obese population.
This doesn't change my thoughts on the study. It seems reasonable to me that people with higher consumption rates of animal protein would have a higher average BMI and it also seems reasonable that the overall average would be 25.5. A little over half of the participants were overweight/obese and a little under half were not. This seems like a good divide to me.
No, the number doesn't change my thoughts about the study. Like Kathy said, it seems like the people were divided fairly even. It may have made the study more valid to use participants who had a higher BMI just to see if they fell into the same results of consuming more animal protein. I would've also liked to have seen more people involved in the study who had a BMI lower than the average just to make it more varied and accurate.
I agree with Tiffany that the study should be done again possibly using a larger sample size. I think this would give us a clearer picture of whether or not consumption of animal protein correlates with higher a higher BMI. Plus there are more obese individuals today so it would be interesting.
I feel that because the study was still able to identify trends in the results, my opinion does not necessarily change. However, I do think that it would be a better representation of the results if the study had a larger range of BMI’s. If this study were to be done again, I would really prefer to see a much larger range in BMI’s to see if there is a distinct difference in the protein intake at each end of the scale.
Considering the time period the study was conducted, the nation's overweight and obesity levels were far lower than today's average BMI. It does not change my opinion on the study but it does raise the question of what major difference (or is it the overall lifestyle pattern) between today's diet and lifestyle and the lifestyles led by persons in that time period. Was it the increased activity that led to lower BMIs? Or was it the decreased portion sizes?
I agree with everyone that a wider range of BMIs may reveal a different set of data. It would be interesting to see this study replicated again since it has been so long since the original study.
As mentioned by most everyone, this does not change my opinion of the study. The results do show a trend in that those who consumed animal fat had a slightly higher BMI than those who did not. I think this shows that there are differences between these proteins and how they affect our bodies.
I agree with the comments on redoing the study to see how different the numbers are today. I would like to see how physical activity might help in decreasing BMI in those that eat animal protein
No, it doesn't change my opinion of the study either. I don't remember my statistics class very well - but am I right that the dividing points for a quartile are determined by the researchers?
My opinion does not change about the study, but I do think that conducting a similar study, including activity, would be interesting to see if there are more drastic differences today because of the higher % of obesity in the country
I agree with Brooke that seeing the range of BMI's would be interesting to see if there where any cut offs with the amount of animal protein consumed and BMI
This number makes me believe that other factors might be more influential. I feel that animal proteins vary greatly, in terms of saturated and total fat. I think that this breakdown might change the baseline.
Many are bringing up the timing of this study. I think that to have any power today this study must be recreated. The demographics and the "typical diet" has changed greatly since than. It would be interesting comparison.
I agree with everyone that it would be interesting to see this study done with today's population. However, if the researchers were interested in just comparing the long term effect of certain amino acids (or combinations) on body weight, it almost seems like this is the kind of research one would do with rats.... Not that I'm promoting animal testing!
This does not change my opinions on the study. Kathy made an excellent point that the groups seem to be evenly divided. They made a reasonable choice that those who consume animal protein could have a higher BMI than people who mainly consume vegetable protein. Many studies have shown that people who use vegetable sources for protein have lower BMIs.
