Quoted from Dr. D
Very interesting thread.

There is a term called 'statistical power' which  calculates the minimum sample size required so that one can be reasonably likely to detect an effect of a given size. For nutritional studies, this often approaches 1000+ participants. Now, times this by four (each blood type) and add controls. Provide each subject with engineered meals and pay for admin followup and experimental work.

Turns out some ideas are bigger than the current experimental model.
Yes, there are four blood types, but a study of just one Blood Type (O for instance) would be a step in the right direction.

Select N type Os.  For three months N/2 subjects would follow BTD; the other N/2 would follow a lacto-ovo-vegetarian diet (no meat, fish or poultry, but dairy & eggs allowed.)

Test before and after three months:
vital signs
waist size
inflammation markers

plus a brief self-assessment survey


Let N=40.  So what?  The two groups are getting nearly the exact opposite diet from what they need, so you'd expect a measurable effect.  A group of grad students at BU could conduct this kind study in two successive semesters.

In another year, do Type A, BTD vs Atkins.


Then critics can attack the study, not the diet.

If this were started this five years ago, we'd have some interesting data by now.

Double-blind of course is impossible, but that doesn't mean it shouldn't be studied.

BTW, in industry we typically use N=5 for each group.

My SWAMI diet is a blend of BTD and GTD Explorer, but I'm not totally compliant.  Also I try to choose foods that have a Low Glycemic index.  DW and DD are A+, probably also Explorer.

I don't think Dr D himself has the resources to conduct these studies. My hope is that others (some of his students, perhaps?) will do some studies based on Dr D's findings, and that, over time, the data will accumulate.

First, we create a billion dollar pharmaceutical company. Then we fund the studies to determine the truth. Then we fix the truth to fit the desired results.

Short of that, we'll have to settle for promoting a results-based health approach that speaks for itself.
