Yeah, it's classic effect size versus p-value and one reason meta-analysis was invented. I find the concerns about lean versus fat mass more convincing but there's lots of issues with the study and the conclusions they're drawing. I also think the "no control group" is very fuzzy. The idea of pre-post with no control group, explicitly (via experimental manipulation) or implicitly (through observation of low/null/absent values of the independent variable) is kinda odd.
