I think it's more likely that this conclusion is true than that it's false. However, the fine article says: "We admitted 10 male and 10 female weight-stable adults". That is a ridiculously small population to start with. Yes, yes, I know it's expensive to have many participants, but part of the broader problem in today's science is that too many experiments are accepted broadly even though they are based on tiny sample sizes. This is an excellent justification for conducting a larger study, not a conclusion in itself.
