Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

An observational study of those who have been prescribed a GLP-1 agonist therapy (yet to commence), for either weight or diabetes management, and are willing to complete dietary records and questionnaires of behaviour and psychosocial health.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Forty individuals (20 for weight management, 20 for diabetes management) living in Australia who have been prescribed a GLP-1 agonist (no previous prescription or no use in the previous 6 months) will be recruited to participate over the initial 3 months of their treatment. Assessments will occur remotely (online) at baseline, 2 weeks, 1 month and 3 months. Optional body composition assessments will be provided at baseline and 3 months for those based in Melbourne, Australia.
