>>Weight loss is rarely the primary goal of FMT and its efficacy in that realm remains unproven.

Well, doesn't this case demonstrate that FMT can be used to have an effect on weight, albeit in the negative sense? So something is going on here, and while the science is unproven, it sure seems like this incident demonstrates that it has promise.

One case doesn't demonstrate anything. There are a million reasons why a someone might suddenly start putting on weight.

Luckily there has been a rapid uptake in FMT and we'll have good correlational data sooner rather than later.
