I would like to see a human study.
I am sticking with the idea/hypothesis that in humans weight is a function of caloric intake and exercise/activity. The bacterial effect on nutrient/calorie absorption having such a minor effect that it constitutes a rounding error.
Science is all about testing hypotheses, and this one looks prime to test.
Thanks for the link.
Agreed. You can have smoke without fire, but it is always a good thing to check. ;-)
