Weight regain after bariatric surgery is one of the most feared — and most misunderstood — parts of the journey. So when does it become a problem, and what can you actually do about it?

 

In this episode, Accredited Practising Dietitian and Dietetics Lead Jennifer Tsoutsoulis from Melbourne Weight Loss Solutions unpacks why some degree of weight regain is a normal part of the post-surgery curve and how to tell the difference between a natural rebound and a genuine red flag.

 

Jennifer explains why the first 12 months after surgery is the "honeymoon period," what happens to hunger hormones beyond that window, and how changes in portions, food quality, and eating routine quietly drive regain over time. She also covers the role of the body's set point, why the scale will often settle slightly above your lowest post-surgery weight and why that's not failure. 

 

For anyone seeing the numbers creep up and wondering whether to panic, Jennifer offers a clear, practical threshold: when to pause, what to check, and who to reach out to first. Tune in to find out what to do next.





Episode Highlights:
Why weight regain is multifactorial and always expected to some degree
What the "honeymoon period" means and why hunger changes after 12 months
How ghrelin, portion creep, and food quality combine to drive regain
The body's set point explained and what a normal rebound actually looks like
The 5kg rule: when to pause, check in, and reconnect with your team
Why GLP-1 medications are now a legitimate tool in managing post-surgical regain
The iceberg analogy: why dietitians, psychologists, and surgeons all have a role
Why obesity being treated as a chronic disease is changing the conversation
