Use of Low-Calorie Sweeteners and Weight: Facts and Myth

Recorded February 10, 2021

Description: Myths about LCS and effects on appetite and weight have been pervasive for years. Because of the continuing proliferation of studies that yield opposing conclusions, practitioners may err on the side of caution and recommend avoidance of sweeteners. However, given that intake of added sugars continues to be excessive and that humans have an innate desire for sweet, clarity on the evidence is needed to support fact-based recommendations for LCS use for weight-related objectives. In this session, speakers will review their recent systematic review work on questions about the relationship between intake of LCS and weight, and how these results fit into the context of the broader evidence, as well as implications for use of LCS as a tool in weight management.
