Weight regain after bariatric surgery is one of the biggest concerns I hear from my clients — and it makes complete sense. You've been through so much to get to this point, and the last thing you want is to see the scales creep back up. The good news? There are practical, proven strategies that can help you protect your results long-term.
In this episode I'm sharing five key tips to help you avoid weight regain after weight loss surgery. Let's dive in.
1. Consume Adequate Protein Every Day
Protein is number one for a reason. Unlike carbohydrates and fat, our bodies don't store protein — which means we need to consume it consistently every single day. Protein is essential for a whole range of metabolic functions, including maintaining and building lean muscle mass, which is critical after surgery.
In the early to medium days post-surgery, getting enough protein can feel really challenging. You might feel like all you're eating is protein — and honestly, that's okay. Hang in there, because as time goes on, it becomes easier to eat more and hit your targets.
One of the most powerful things about protein is that it's a high-satiety nutrient — it keeps you fuller for longer with less energy intake. I call this "the power of protein," and it's something I encourage all my clients to lean into, especially as their appetite increases over time.
How much protein you need will vary from person to person and will evolve over time. This is something your bariatric dietitian can help you calculate based on your individual circumstances — so don't be afraid to ask!
2. Eat Regular Meals
Skipping meals is one of the most common habits that can work against you after surgery. Eating regularly — getting into a consistent daily schedule — is so important for managing your appetite, hitting your protein goals, and avoiding the trap of arriving at a meal absolutely ravenous.
When you skip meals and get too hungry, it becomes really hard to eat slowly, and overeating becomes much more likely. That discomfort can then trigger another long gap before eating, and the cycle continues.
In the early to medium days post-surgery, I typically work with clients on eating five small, distinct meals a day. Over time, we can adjust that as appetite and capacity change. A "distinct meal" means eating slowly, stopping when you're satisfied (or after 30 minutes), and keeping those meals structured rather than sliding into grazing behaviour.
One area that can be a real hotspot for many people is eating after dinner. This is a vulnerable time for grazing and snacking on discretionary foods. The goal is to finish dinner feeling comfortable and done. If you do need an evening snack due to an early dinner, make it a deliberate, high-protein option — not a couch-grazing session.
3. Drink Mostly Low-Energy Fluids
This one can creep up on you gradually. After surgery, high-energy drinks can slowly make their way back into your daily routine — a milky coffee here, a smoothie there — and over time, those liquid calories add up and can contribute to weight regain.
The key is to stay mostly on low-energy fluids: water, herbal teas, black or white coffee with minimal additions. High-energy fluids to be mindful of include smoothies (unless they're a deliberate high-protein meal replacement), fruit juices, soft drinks, alcohol, and similar beverages.
This doesn't mean never — it's about awareness and making sure most of what you're drinking isn't quietly adding significant calories to your day.
4. Move Your Body Regularly
The research is clear: people who move their bodies regularly after weight loss surgery are more likely to maintain their results. But movement doesn't have to mean putting on the lycra and heading to the gym (although if you love the gym, go for it!).
Find movement you genuinely enjoy — dancing, riding a bike, walking the kids to school, taking the stairs, bowling, a walk in the park. When you enjoy the activity, you're far more likely to keep doing it.
If you're new to regular movement or have previous injuries, I'd always recommend checking in with your GP before starting a new exercise routine. An exercise physiologist can also be a wonderful resource to help you find safe, pain-free ways to get moving.
5. Reach Out for Support
There's a lot of research showing that people who access follow-up support after weight loss surgery do better long-term. Yet so many people feel like they should be able to manage it all on their own — and that belief can actually hold you back.
Needing support after bariatric surgery is completely normal and expected. There is so much change involved — physically, emotionally, and behaviourally — and things will come up that you never anticipated. Having a support team to tap into regularly makes a real difference.
Your support team might include your bariatric surgeon, bariatric nurse, GP, psychologist, and dietitian. And don't underestimate the power of personal cheerleaders in your life — the people who celebrate your wins, remind you how far you've come, and lift you up when things get tough.
