Obese people had differences in behaviour, but the statistical comparisons DIDN'T SHOW A SIGNIFICANT DIFFERENCE Pretty major issue, that
Anyway, the paper is abhorrent regardless, but I think it also shows some worrying signs of being constructed after the fact from a dataset of a trial with different aims

Because the randomization was simply fasted vs breakfast, the causal attribution for this study should be comparing those two groups, not the subgroups of obese vs lean
