    FMT Body mass index changes after fecal microbiota transplantation for recurrent Clostridioides difficile infection (Feb 2025, n=401) "no significant relationship between donor BMI and changes in recipient BMI after FMT"

    https://journals.sagepub.com/doi/10.1177/17562848251321121 There are many caveats to this study. A main one is that BMI includes muscle mass, so it's not a good measurement of obesity or being overweight. Body fat is a better measurement. I know of someone who did FMT from a donor who was...

    https://www.thelancet.com/journals/lanmic/article/PIIS2666-5247(24)00302-1/fulltext A group from Aarhus University Hospital, Denmark. One of the few studies looking at bristol stool type. They found the opposite of my hypothesis. The caveats are that it's for C. difficile, which is very easy...
