Wondering whether snacking is okay after weight loss surgery? The answer isn’t always “no” — it’s about why, when and what you’re eating.

Snacks should be guided by hunger, rather than habit, boredom or simply having food available. If you are genuinely hungry between meals, a small, nutritious snack can be a helpful part of your eating plan.

Aim to choose snacks that contain protein and fibre, which can help you feel satisfied and support your nutritional needs. As a general guide, keep snacks to under 120 calories (500kj).

Remember, everyone’s needs and eating patterns after surgery are different. If you’re unsure what makes a good snack, our dietitian Sarah is always happy to provide ideas and talk through your individual needs.

If you’re hungry between meals, don’t ignore it — let’s make sure your snack is working for you, not against your goals💙

💛 R U OK? Day 💛

Today is a reminder to check in on the people around us — not just the ones who seem to be struggling, but anyone who might be having a difficult time behind the scenes.

Many of us experience challenges with our mental health at some point in our lives. Sometimes we talk about it, and sometimes we don’t. That’s why a simple question like “Are you OK?” can mean so much.

If someone you know has been quieter than usual, seems overwhelmed, or simply comes to mind today, reach out. Send a message, make a call, grab a coffee or sit with them.

You don’t need to have mental health training to make a difference. You don’t need the perfect words or all the answers.

Sometimes, simply showing up, listening without judgement and letting someone know you care is enough💛

So today, ask the question — and genuinely listen to the answer.

There are various types of exercise, each offering unique benefits:

🔹Cardiovascular (aerobic): Activities like running, cycling, swimming and walking improve heart health, endurance and burn calories.

🔹Strength Training (anaerobic): Weightlifting, resistance bands and bodyweight exercises like squats and push-ups help build muscle and boost metabolism.

🔹Flexibility and Mobility: Yoga, pilates and stretching improve flexibility, posture and range of motion.

🔹Balance and Stability: Exercises like tai chi, balance boards or stability ball workouts enhance co-ordination and prevent falls.

🔹High-Intensity Interval Training (HIIT): Short bursts of intense exercise followed by rest, great for improving fitness quickly.

🔹Low Impact: Swimming, cycling and walking reduce stress to joints while offering full body workouts.

Incorporating these after weight loss surgery can help you maintain your weight loss.

🌸 Happy Spring! 🌸

Spring is the perfect time for a fresh start — and that includes getting back into exercise if your routine has slowed down over winter. 🌿

If you’ve been less active over the colder months, don’t be hard on yourself. Life happens, routines change, and sometimes we simply need a break. There’s no guilt and no need to “make up” for lost time.

Just start where you are. 💚

Take a walk, go for a swim, stretch, get back to the gym, or try something you genuinely enjoy. You don’t need to do everything at once — even small amounts of movement can be a great way to get started.

Forget perfection and focus on progress. Celebrate every little win and remember that it’s never too late to begin again.

🌸 Happy Spring! Here’s to fresh starts, feeling good and moving in a way that makes you happy. 💪

Liquid calories are calories consumed through drinks like juice, soft drinks, milkshakes, alcohol, meal replacements, and milky coffees.

While protein shakes can be helpful for hydration and protein needs during the early stages of recovery after bariatric surgery, it’s important to stay mindful as time goes on. Because liquids pass quickly through your stomach without making you feel full, these calories can add up fast, potentially leading to poor weight loss or even weight regain.

Drinks high in sugar and fat such as thickshakes, are more likely to trigger dumping syndrome. For the best results, focus on low-sugar and low-fat beverages, and remember that protein-rich drinks are generally only needed if you aren’t hitting your protein goals through food alone.

For Exercise Right Week, let’s talk about the real secret to long-term success after weight loss surgery: exercise enjoyment.

If you view movement as a chore or a punishment, it won’t stick. But when you find activities that genuinely bring you joy, consistency follows naturally.

Post-surgery exercise isn't about breaking records, it's about celebrating what your body can do. Start small, listen to your body as it heals and focus on the incredible boost to your mood and energy.

Recovery after weight loss surgery is a journey, and staying hydrated is the single most important task on your daily to-do list. Because your stomach capacity is significantly smaller, it is much easier to become dehydrated if you aren’t proactive.

Proper hydration doesn't just keep thirst away, it’s essential for:

🔹Faster healing and tissue repair
🔹 Preventing constipation
🔹 Avoiding "brain fog," fatigue and headaches
🔹 Reducing the risk of kidney stones and hospital readmission

Aim for 1.5L to 2.0L of total fluids daily. Remember to sip consistently throughout the day and keep your fluids separate from your meals to maximise your intake.
