Dance-Based Interventions for Mental Health: A Comprehensive and Quality-Sensitive Umbrella Review of Definitions, Measurement Practices, and Evidence Fragmentation.

Obesity affects approximately 16% of the global adult population, with projections exceeding one billion affected individuals by 2030 [, ]. Weight loss is the primary therapeutic strategy and improves obesity‐related metabolic risk factors []. However, long‐term weight loss maintenance remains a major challenge. Most individuals regain lost weight within 1 year, and even modest weight regain (2%–6%) is sufficient to attenuate or reverse the metabolic benefits achieved with clinically significant weight loss [–]. This highlights the critical need for strategies that promote not only effective weight loss but also long‐term weight maintenance. Data suggest that weight loss and weight maintenance are physiologically and psychologically different in many respects. Therefore, individuals may require distinct interventions aimed at temporarily sustaining a negative energy balance during weight loss versus permanently maintaining energy balance after weight loss []. However, weight regain occurs regardless of how weight loss is achieved, whether through lifestyle changes, including behavioral therapy, bariatric surgery, or pharmacotherapy []. The process of periodically losing and gaining weight, similar to the up‐and‐down movement of a yo‐yo, is commonly called “weight cycling,” “weight fluctuation,” or the “yo‐yo effect,” and presents its own set of health challenges []. Although the potential health risks associated with weight cycling (WC) are concerning, it is equally important to recognize the well‐documented cardiometabolic risks of sustained obesity, including chronic inflammation, insulin resistance, and cardiovascular complications []. This underscores the need for personalized interventions that balance the potential harms of WC with the adverse effects of persistent obesity.
