Weight Management · Adelaide GP
Weight management GP in Adelaide
Health-focused, non-judgmental care, built around you, not a program.
There's no one-size approach here. Weight is shaped by biology, circumstances, history, and a hundred things that aren't about willpower. Whatever's brought you here, I'd like to understand it properly before we work out what would actually help.
This isn't about how you look.
It's about how you feel.
Weight is one of the most complicated and most stigmatised topics in healthcare. Patients often arrive having already tried many things, diets, exercise programs, calorie-counting, and feeling like they've failed. Almost always, that framing is wrong.
Body weight is regulated by complex hormonal systems, genetic factors, sleep quality, stress, medications, and underlying medical conditions. The research is clear: sustained weight management is genuinely difficult, and willpower is only a small part of the picture.
My approach starts with understanding your particular situation, your health history, your lifestyle, what's worked or not worked, and what's actually achievable and sustainable for you. The goal is a plan that fits your life, not a generic protocol that asks you to fit around it.
Reasons people come in
You don't need to meet all of these, or any.
- Weight that's been gradually increasing despite efforts to address it
- A new or worsening health condition linked to weight, blood pressure, blood sugar, joints
- Fatigue, poor sleep, or low energy affecting daily life
- A feeling that lifestyle alone hasn't been enough, and you want to understand your options
- A recent diagnosis of prediabetes or type 2 diabetes
- Interest in understanding whether medication might be appropriate as part of a plan
- Simply wanting a non-judgmental conversation with a GP about where to start
You don't have to have a specific goal or a clear plan. Coming in to talk is a reasonable first step.
It was never just willpower.
One of the most persistent and harmful misconceptions in weight management is that weight is simply a matter of discipline, eat less, move more, want it badly enough. The biology tells a different story.
Hunger and fullness are regulated by a complex set of hormones. Ghrelin, often called the hunger hormone, rises when the body perceives a calorie deficit, driving appetite upward. At the same time, hormones like leptin and GLP-1 (glucagon-like peptide-1) signal fullness and reduce appetite, and in many people who have struggled with their weight over time, these signals don't function the same way they do in people who haven't.
Research on twins consistently shows that body weight has a substantial genetic component. A landmark study published in the New England Journal of Medicine found that identical twins raised in completely different households still had very similar body weight, with genetic factors accounting for roughly two-thirds of the variation in BMI. A large systematic review across 88 twin studies and over 140,000 twins placed the heritability of BMI between 47 and 90%, with a median around 75%. That doesn't mean genetics are destiny, but it does mean that two people can follow the same program and experience very different results, and neither of them is failing.
Understanding this biology matters, not because it removes personal agency, but because it shapes what kinds of interventions are actually likely to work for a particular person.
The hunger hormones, briefly explained
- Ghrelin produced mainly in the stomach, rises before meals and when calorie intake is reduced. Drives appetite and can increase significantly during dieting, making sustained calorie restriction biologically difficult.
- Leptin secreted by fat tissue, signals to the brain that energy stores are sufficient. In some people with higher body weight, leptin resistance develops, meaning the brain doesn't receive or respond to the signal effectively.
- GLP-1 (glucagon-like peptide-1), released after eating, promotes fullness, slows gastric emptying, and influences insulin secretion. GLP-1 receptor agonist medications work by enhancing this system.
- Insulin central to blood sugar regulation. Insulin resistance, common in people with higher body weight, contributes to a cycle that makes both weight management and metabolic health harder to address independently.
- Cortisol the stress hormone. Chronically elevated cortisol, often from poor sleep or sustained psychological stress, promotes fat storage, particularly around the abdomen.
A plan built around your situation.
There's no default program here. Every consultation starts with a proper history, and from there, we work out together what makes sense. Sometimes that's a structured lifestyle plan with referral to a dietitian or exercise physiologist. Sometimes it's investigation of an underlying condition that's been making everything harder. Sometimes medication is part of the picture. Usually it's a combination.
Lifestyle is always the foundation. That doesn't mean it's the only thing, it means it's what sustains results over the long term, and anything else we add sits alongside it, not instead of it.
A full picture, first
We start with your history, what's changed, what's been tried, what else is going on medically. Medications that affect weight, sleep quality, thyroid function, insulin resistance, mental health, all of this is part of the assessment, not an afterthought. Investigations are tailored to what comes up.
Lifestyle, always the foundation
Nutrition, movement, sleep, and stress are the pillars that everything else depends on. My approach is practical and realistic, not prescriptive. What's achievable given your actual circumstances? Some patients can make significant changes quickly. Others have real barriers, mobility, finances, shift work, caring responsibilities, and the plan has to account for that honestly.
Addressing underlying factors
If there are medical factors contributing, uncontrolled sleep apnoea, insulin resistance, thyroid dysfunction, medications that affect weight, addressing those is often part of making everything else more effective. It's worth investigating properly before concluding that nothing works.
Medication, part of the picture, if indicated
For some patients, medication is a clinically appropriate part of a broader plan. This is a conversation that happens after a proper assessment, not before. I can initiate medical therapy where it's indicated, and we'll discuss what that looks like, what to expect, what happens long-term, and how it fits alongside everything else.
Referral when it adds value
A dietitian, exercise physiologist, or psychologist can make a significant difference for many patients. I'll refer when there's a clear benefit, and when access allows. Complex cases that warrant specialist input from an obesity physician or bariatric surgeon are also something I can help navigate.
Regular review and honest conversation
Weight management is long-term work. We'll review regularly, adjust the plan as needed, and have honest conversations about what's working and what isn't. If medication is part of your plan, we'll also talk openly about what happens when and if you stop, including the importance of building sustainable habits that carry forward.
Lifestyle isn't a word for what didn't work.
When lifestyle interventions haven't produced lasting results, it's often because the approach didn't account for the specific barriers involved. These are the areas I look at, not as a checklist, but as interconnected levers that affect each other.
Nutrition
What works is highly individual. Rather than prescribing a specific diet, the goal is understanding your current eating patterns, what's realistic, and what changes are most likely to make a meaningful difference in your metabolic health, not just the scales.
Movement
Exercise matters, but less so for weight loss than most people think, and more so for metabolic health, mood, sleep, and long-term outcomes. Finding a form of movement that's sustainable given your circumstances is far more valuable than the "optimal" protocol you stop after six weeks.
Sleep
Poor sleep directly affects hunger hormones, ghrelin rises, appetite increases, and cravings for energy-dense foods tend to go up. Sleep apnoea, in particular, is common in people with higher body weight and can make weight management significantly harder. It's worth investigating.
Mental wellbeing
Stress, anxiety, depression, and emotional eating all have complex relationships with weight. Addressing mental health isn't a side issue, for many people it's central to sustainable progress. I treat these as part of the same picture, not separate problems.
Medications & medical factors
A number of common medications, antidepressants, steroids, some blood pressure medications, antipsychotics, insulin, can contribute significantly to weight gain. Thyroid conditions, insulin resistance, and polycystic ovary syndrome (PCOS) are also common contributing factors worth identifying.
Sustainability
The most effective intervention is the one you can actually maintain. Short-term results are achievable with many approaches. The harder question is what the plan looks like at 12 months, at 2 years, and that's the question worth starting with, not finishing with.
When medication is part of the plan
There are patients for whom lifestyle modification alone is not sufficient, because of the underlying biology, because of barriers that can't easily be removed, or because a medical condition means that medication is indicated on clinical grounds regardless of weight.
For those patients, medication can be a genuinely useful part of a broader plan, not a shortcut, and not a substitute for lifestyle work, but a tool that makes the harder work more achievable.
Several medications are approved by the Therapeutic Goods Administration (TGA) for weight management in Australia. They work through different mechanisms, some reduce appetite through effects on the brain and gut hormones, some reduce fat absorption, and some have weight management benefits alongside their primary use for conditions like type 2 diabetes. Which option is most appropriate depends entirely on the individual, their medical history, other conditions, medications they're already on, and what's realistic for them.
I can initiate medical therapy where it's clinically indicated and discuss what each option involves, what to expect, and how it fits alongside everything else. Relevant eligibility criteria and current PBS status are always discussed at the time of consultation, these change, and I work from current guidance rather than making assumptions.
One thing I always address when medication is part of the plan: what happens if and when it stops. For most people, sustained results depend on the lifestyle habits built alongside the medication, not the medication alone. That's an honest conversation that happens from the beginning, not as an afterthought.
Things I hear often, and what I'd actually say
"I just need to find the right diet."
The idea that weight management comes down to finding the correct eating plan, low carb, low fat, high protein, intermittent fasting, is one of the most common frameworks patients bring in. It assumes there's a universally superior approach that simply hasn't been found yet.
The best diet is one you can actually sustain, and that looks different for everyone.
The research is consistent: over the long term, different dietary approaches tend to produce similar outcomes. What matters more than the specific diet is whether it's practical, satisfying, and compatible with your actual life. Adherence outperforms optimisation. A plan that works for 12 months beats one that's theoretically ideal but abandoned in six weeks.
"Skipping meals gives my metabolism a reset."
Intermittent fasting and meal skipping have attracted a lot of attention, often framed as metabolically beneficial in ways that go beyond simply eating less. Patients sometimes arrive convinced that the timing of eating matters more than what's being eaten.
Fasting works when it helps you eat less overall, not because it resets anything.
The evidence for intermittent fasting is real but more modest than the popular version suggests. It works for some people because reducing eating windows often reduces total calorie intake, not because of a metabolic effect unique to fasting. For others, long gaps between meals raise ghrelin levels significantly, leading to compensatory eating later. Whether it's a useful tool depends on the individual.
"I just need more willpower."
Patients say this. Family members say it. It's often internalised after years of trying things that didn't produce lasting results. It's also one of the least useful frameworks for understanding or addressing weight.
Your hunger hormones aren't a character flaw.
When you reduce calorie intake, ghrelin rises and drives appetite upward. Metabolic rate adapts. The body works to restore its previous weight, actively and persistently. Research including large twin studies shows a substantial genetic component to body weight. Sleep deprivation, chronic stress, and certain medical conditions all shift the biological baseline further. The right approach works with your biology, not simply against it.
Time to actually cover what matters
Weight management consultations are a dedicated conversation about your health, your history, and your circumstances. There's no value in rushing a conversation this important. The first appointment is about building a complete picture before anything else.
Telehealth available for existing patients who have attended in person within the past 12 months, or who are registered with Pro Health Care Glenelg via MyMedicare. New patients must attend in person first.
Things patients often ask
A GP is often the right starting point, and for many patients, the right long-term partner. I can assess the full medical picture, identify contributing factors, initiate medical therapy where appropriate, and co-ordinate referrals when they add value. Specialist referral is available when the complexity of the case warrants it.
No. Whether this is your first time addressing weight seriously or you've been trying for years, you're welcome. There's no threshold you need to have crossed. The conversation is about understanding where you're at, not judging what you have or haven't done before.
No. Medication is one option within a broader plan, and it's not the right option for everyone. The consultation starts with understanding your situation properly. Whether medication is appropriate, which option, and how it fits alongside lifestyle changes are all things we work out together based on a thorough assessment.
This is a common and completely valid situation. Mobility limitations, chronic pain, fatigue, and other physical constraints are real barriers, and they're part of what the assessment needs to take into account. A plan that ignores your actual circumstances isn't a useful plan. We'll work with what's genuinely possible.
Always how you feel, and specifically, your health. Metabolic health, cardiovascular risk, blood pressure, blood sugar, energy, sleep, and quality of life are the clinical goals. Appearance might be part of what motivates you, and that's understandable, but the medical focus is on your wellbeing, not a number or a size.
For most people, weight does return after stopping medication if lifestyle habits aren't established to support things independently. That's an honest conversation I have with every patient where medication is part of the plan, because it shapes how we think about using the medication, what we try to build alongside it, and what long-term looks like. It's not a reason to avoid medication for the right patient, but it is something to plan around.
Telehealth is available for existing patients who have attended in person within the past 12 months, or who are registered with Pro Health Care Glenelg via MyMedicare. New patients need to attend in person first, an initial weight management assessment benefits from being in person.
