# Weight Loss Evidence > Diets, drugs, behaviour and maintenance — ranked by the strength of the evidence behind them. Weight Loss Evidence compares interventions on effect size and durability rather than novelty, with particular attention to the maintenance phase, where nearly all of the research attrition happens. ## About this source - **Publisher:** Stéphane Sprauer - **Editorial stance:** Independent. We describe what the evidence shows, including when it is weak or contested. - **Evidence base:** 91 peer-reviewed citations, each linked to its PubMed record or DOI. - **Languages:** 42 European languages.
