The writer cited a number of components, together with implausible knowledge, as causes to yank the research.

“Tempting although it’s to alert readers to an ostensibly easy and apparently useful weight reduction help, at current the outcomes of the research are unreliable, and journalists and others ought to now not reference or use the outcomes of this research in any future reporting,” stated Helen Macdonald, Publication Ethics and Content material Integrity Editor at BMJ Group, in a statement from BMJ.

Too good to be true

Researchers in Lebanon carried out the research, first published in March 2024 within the journal BMJ Vitamin, Prevention & Well being.

It wasn’t lengthy earlier than outdoors scientists started to lift crimson flags concerning the statistical evaluation underpinning the research’s findings, nonetheless.
