Small choices. More fibre. 🌿

High-fibre foods don’t need to be expensive or complicated. Lentils, split peas, wholemeal pasta, fruit and vegetables can all bring more fibre to everyday meals.

Dietary fibre supports bowel regularity and digestive health. A few simple ways to include it:

🥣 Add lentils to soups and casseroles.
🍝 Choose wholemeal pasta.
🍐 Enjoy fruit with its skin, where edible.
🥦 Include vegetables alongside meals.

Serving size matters, the graphic shows the portions behind the numbers.

Build fibre gradually and keep fluids up. After bariatric surgery, food texture, portions and timing should follow the advice of the treating team.

Resistance training during weight loss is one of the most effective ways to protect muscle, strength and long-term health. Whether weight comes off through surgery, GLP-1 medicine or lifestyle change, some of what is lost can be muscle unless the body is given a reason to keep it.

The good news is that it does not take much. Two short sessions a week, a few simple movements and enough protein make a real difference.

Save this for your next session, and send it to someone who has just started their weight loss journey.

Heading into theatre today for an oesophagectomy, an operation to remove part of the oesophagus to treat cancer.
It's one of the biggest operations in upper GI surgery, and a side of my work many people don't see.

Alongside bariatric surgery, I perform complex laparoscopic cancer surgery of the oesophagus and stomach. These two areas are more connected than they sound.

Obesity is one of the strongest risk factors for oesophageal adenocarcinoma, the type of oesophageal cancer most closely linked to weight. Excess abdominal weight increases pressure on the stomach and drives acid reflux.

Over years, that reflux can change the lining of the oesophagus (Barrett's oesophagus), and in a small number of people that change progresses to cancer. People living with obesity have roughly double the risk, and it climbs further as BMI rises.

The symptoms worth acting on: new heartburn or reflux starting after 55, especially in men. Food sticking or difficulty swallowing. Weight loss you're not trying for. Vomiting, vomiting blood, or black stools. Anaemia on a blood test. Reflux that isn't settling with medication.

If that sounds like you or someone you love, see your GP and ask whether a gastroscopy is needed. Found early, oesophageal cancer is far more treatable.

Treating reflux and treating obesity is also cancer prevention. That's why my cancer work and my bariatric work sit side by side.

Send this to someone who's been putting off mentioning their heartburn.

In 1949, at a laboratory in Bar Harbor, Maine, researchers noticed a mouse that ate constantly and grew far heavier than its littermates. In the 1970s, Douglas Coleman joined its circulation to that of a lean mouse.

The hungry mouse began eating less and losing weight. Something in normal blood was telling the brain to stop, and this mouse was missing it.

In 1994, a team at Rockefeller University found the missing signal. It was a hormone made by fat cells. They named it leptin, from the Greek leptos, meaning thin. Leptin tells the brain how much energy the body has stored.

Since then, more than 600 signals from fat tissue have been identified. Fat talks to the brain about hunger, to the liver and muscle about insulin, and to the ovaries through oestrogen.

As fat tissue expands, the messages change. Protective signals fall, inflammatory signals rise, and the brain becomes less responsive to leptin. Hunger can stay switched on despite plenty of stored energy. Fat around the organs drains directly to the liver, which is why where fat sits matters as much as how much there is.

Obesity is a disorder of signalling, not a failure of discipline. That is why effective treatment aims to change far more than a number on the scale.

We treat the biology. Not the willpower.

Share this with someone who still thinks fat is just storage.

Spring has well and truly arrived in Dunedin ☀️

People often ask what gets me moving at the weekend. Honestly? It's these two. Molly and Coco don't care about the weather, my step count or how busy the week was. They just want to get to the beach, and that's all the motivation I need.

Movement doesn't have to be a gym session or a training plan. Sometimes it's just a walk on the sand with the people (or pups) you love.

So I'm curious: what gets you moving on a Sunday? 👇

Some messages deserve a whole wall.

Obesity care needs assessment, treatment, follow-up and ongoing support.

At Southern Weight Loss in Dunedin, that means taking time to understand each patient’s health, discussing suitable treatment options, and planning the care that follows.

Bariatric surgery is one part of that pathway. Dietitian input, psychological support and regular reviews are part of the care around it.

Led by Upper GI and Bariatric Surgeon Mr Mark Grant, Southern Weight Loss welcomes patients from across Otago and Southland.

Compassionate care. Clear information. A conversation without judgement.

Book an assessment. No GP referral needed.

GLP-1 weight loss medications and the newer dual agonists work by quieting appetite, which means what people eat matters more than ever.

When someone is eating far less, every mouthful has to do more work.

Without the right guidance, a meaningful share of the weight lost on these medications can come from muscle rather than fat. Muscle supports strength, metabolism and long-term health, so protecting it is one of the most important parts of treatment.

That's where an expert dietitian makes the difference. A dietitian helps set realistic protein targets, makes small meals nutritionally complete, manages side effects like nausea or constipation, and builds eating habits that last beyond the prescription.

At Southern Weight Loss, dietitian care sits at the centre of both our medical and surgical pathways across Dunedin, Otago and Southland. Medication changes the biology. Good nutrition helps people build a healthier life on top of it.

If your care journey feels like 12 open tabs, you're not doing it wrong.

One appointment said one thing. Another said something else. There's a diet that worked for a while, a medication you stopped, a blood test you meant to follow up, and a search history you'd rather nobody saw. Every tab is open, and none of them talk to each other.

You don't have to close them all before you reach out. Start with what's hardest to ignore: your symptoms, your history, and the parts of daily life that have changed. We'll help you sort the rest.

Your first appointment is a conversation, not a test. No GP referral is needed, and if surgery is on the table, our surgeon, dietitian and psychologist work together so everything finally sits in one place.

You don't need every answer on day one.

Long one in Wānaka today, but one of the good ones.

Two of my patients reached their final two-year follow-up after surgery this afternoon. Sitting across from them and looking back at where they started, it's hard to put into words how much has changed. Their health, their energy, the way they talk about the future.

I want to be clear about something: the surgery was only ever the starting point. What I saw today was two years of their own hard work. The protein targets, the supplements, the dietitian appointments, getting back into movement, turning up to every check-in. That's theirs, not mine.

People sometimes ask what the best part of this job is. Days like today are the answer. Watching someone finish their two-year follow-up with the confidence that they've got this is about as rewarding as it gets.

Tired, but very grateful. Thanks Wānaka, see you next time. 🏔️

The hills are alive. The food noise? Finally quieter.

The Sound of Quiet. Our Central Otago take on a cinema classic, with a different kind of freedom at its heart.

“Food noise” describes persistent thoughts about food that can intrude on everyday life. What to eat next. When the next meal is. The pull of food even when physical hunger has settled.

It can take up a remarkable amount of mental space.

Appetite is influenced by signals between the gut and brain, including hormones involved in hunger and fullness. Bariatric surgery changes some of these signals. Medical weight management can also act on appetite pathways, helping some people experience less hunger, fewer cravings and quieter food thoughts.

Responses vary, and food noise does not disappear for everyone. But for some, treatment creates room to enjoy a conversation, a walk or a view without food constantly taking centre stage.

That is the story behind this poster.

Southern Weight Loss offers bariatric surgery and medical weight management with Mr Mark Grant and a multidisciplinary team, based in Dunedin and serving Otago and Southland.

Self-referrals welcome. No GP referral needed.

We treat the biology. Not the willpower.
