There are so many places for errors to creep in. Given the slow time scale for change 4 weeks of weight maintenance may not be sufficient to guarantee energy balance.

The fact that they didn’t monitor diet adherence during the outpatient phase is also grounds for skepticism.

It seems that the study makes the participant lose 10-15% weight, then diets them, but does not have any info on weight loss or gain during the dietary period. I wonder if numbers for weight after the weeks of diet might be useful to flag comparative over-eating; all diet participants, being in energy imbalance, should continue modest weight losses, right? (I’m a novice, so please correct me if I’m mistaken)

Because another experimental error might be that the diets are erroneously carb-rich, thus giving off a more carby RQ signature, might it not? The lions share of the FQ/RQ discrepancy seems to be in the VLC end of the diet, and I guess that the VLC would be most affected by some extra ketchup. But I imagine that it would be easier to differentiate over-eating and overcarbing if you knew whether energy-imbalance had been maintained…
