One should note that the participants (N=20) were divided into two groups with the respective regimens, and put on a controlled calorie diet for the rest of the time. Evaluation was after four weeks.

This study tells us very little. Small sample size, constrained diets without a proper control (protein pacing without IF, or no restriction at all), short evaluation horizon.

There could be something to it, but as they say, that requires a lot of further study. In itself this study provides a hint, certainly nothing close to an authoratative conclusion.
