Prevailing recommendations on reporting weight loss after bariatric and metabolic surgery are not evidence-based. They promote the outcome metric percentage excess weight loss (%EWL), sometimes indicated as percentage excess body mass index loss (%EBMIL). Many studies proved that this popular outcome measure, in contrast to other weight loss metrics, is inaccurate and error-sensitive when comparing weight loss within and between studies. It is inappropriate for assessing poor weight loss response and weight regain as well. The percentage (total) weight loss metric is the best alternative. The Dutch Society for Metabolic and Bariatric Surgery (DSMBS) recommends to stop using the %EWL (or %EBMIL) metric as primary outcome measure in all cases and calls on the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) to propagate this evidence-based recommendation.
关于减肥和代谢手术后体重减轻报告的现行建议并非基于证据。这些建议推崇结果指标超重体重减轻百分比（%EWL），有时也表示为超重体重指数损失百分比（%EBMIL）。许多研究证明，与其他体重减轻指标相比，这种流行的结果测量方法在比较研究内部和研究之间的体重减轻时不准确且对误差敏感。它也不适用于评估体重减轻反应不佳和体重反弹情况。（总）体重减轻百分比指标是最佳替代方案。荷兰代谢与减肥外科学会（DSMBS）建议在所有情况下停止使用%EWL（或%EBMIL）指标作为主要结果测量方法，并呼吁国际肥胖与代谢疾病外科学会联合会（IFSO）推广这一基于证据的建议。
