Researchers called for future trials to explore the the effect of GLP-1RAs on the composition of weight loss during and after treatment. Steven Luo, also an author on the study, said: 'When stopping weight loss drugs, doctors and patients should be aware of the potential for weight regain and consider ways to mitigate this risk.
