I think it's generally true that "people who do X (and make no other changes)" do not lose weight for all values of X except some very unhealthy things, and those unhealthy things are generally followed by rebound weight gain anyways. Almost everything to do with weight loss verges on pseudo-science and the field is constantly flooded with misinformation from people peddling something. Focusing on weight loss as a goal in and of itself is thus pretty much always a road to pain anyways.
