Choosing to have gastric sleeve surgery is one of the most empowering health decisions you can make. It’s not just about losing weight – it’s about reclaiming your health, confidence, and vitality so you can live a fuller life.
At Body Genesis Institute, with locations in both Melbourne and Hobart, we’ve supported hundreds of individuals through this journey – from the moment they decide to have surgery, through recovery, and well into long-term success.
This article will guide you through what to expect in the first 12 months after gastric sleeve surgery, the milestones to look forward to, and how to make the most of the support systems available to you.
The First 4 Weeks: Healing and Adjusting
Your first few weeks after surgery are about recovery and adapting to your new stomach size.
- Physical recovery: You’ll spend one to two nights in hospital. Most people return to light daily activities within 1–2 weeks.
- Dietary progression: You’ll move through a carefully structured plan –from runny liquids to free fluids with progress to purées, then soft foods.
- Support from our team: At Body Genesis, our dietitians will guide you through each phase to ensure your nutrition is balanced and your hydration stays on track.
- Emotional adjustment: It’s common to feel a mix of excitement and vulnerability.
This is where our psychology and coaching support helps you navigate the emotional side of change.
Tip: Start journaling your daily meals and moods –all our patients receive a journal title ‘Creating a New You”, crafted specifically to help you develop awareness around your food choices and healthy habits .
Months 2–4: The start of an exciting journey
As your body continues to heal, you’ll start noticing significant changes – not just in your weight, but in your energy and confidence.
- Steady weight loss: Most people lose between 15–25% of their total body weight in the first three months.
- Re-introducing exercise: Gentle walking and resistance exercises help preserve muscle mass and boost metabolism. Our exercise physiologists can create a tailored plan to match your recovery stage.
- Mindful eating: This is when learning to eat slowly, chew well, and tune into hunger cues becomes crucial.
Our patients often say this is when they “feel lighter on the inside” – not just physically but mentally. At Body Genesis, we encourage attending “Success Beyond Scales” – our monthly educational webinars run by Dr Arun to help connect with others on the same path and learn in a safe nurturing environment.
Months 5–8: Fine-Tuning Nutrition and Mindset
By now, your new eating habits are becoming more natural, and your focus shifts from “what not to eat” to how to nourish your body for life.
- Protein first: Aim for 60–80g of protein daily to maintain muscle and prevent fatigue.
- Vitamins and supplements: Our team ensures you’re on the right regimen to prevent deficiencies.
- Addressing plateaus: It’s normal for weight loss to slow around this time. Our bariatric physicians can review your nutrition, hormones, and metabolism to help you stay on track.
Emotionally, this is when old habits can resurface. Our mindset coaches and psychologists help you recognise triggers, develop resilience, and realign with your “why.”
We often remind our patients: Surgery changes your stomach; coaching changes your mind.
Months 9–12: Consolidating a New Normal
As you approach the one-year mark, your body has adapted beautifully to its new rhythm. You’re likely feeling healthier, moving more freely, and rediscovering things you once avoided – hiking, dancing, travel, or simply shopping for clothes that fit comfortably.
- Body composition shifts: You’ll see more toning and definition as your muscle-to-fat ratio improves.
- Skin and energy care: Our team can guide you on skin nutrition, hair care, micronutrients, and if needed, referrals for reconstructive advice.
- Relationship with food: Many people rediscover food as a source of nourishment rather than comfort.
One of our patients shared: “At 12 months, I finally stopped worrying about diets. I was just living healthily – naturally.”
To help sustain this mindset, we encourage continued participation in our Success Beyond Scales Program – an 8-week lifestyle mastery course focused on mindset, mindfulness, and long-term vitality.

You’ve built sustainable habits.
