Two-thirds of Australian adults (around 13 million people) are now living with overweight or obesity. That number is not in dispute. It comes from the latest Australian Bureau of Statistics National Health Survey, and it has been rising, with brief plateaus, for the better part of forty years.

What is in dispute, and what gets discussed less, is what we have been telling those 13 million people during that period. The conventional advice has been broadly the same for a generation. Eat less. Move more. Some version of try harder. Sometimes a printed leaflet, sometimes a referral to a dietitian, sometimes a brief conversation that ends with the standing instruction. The advice has been delivered, on average, by the GPs who carry the load of every other chronic condition Australians develop. And, by the most generous reading of population-level outcomes, it has not worked for the great majority of the people it has been delivered to.

This is the simplest, hardest fact of weight management in Australia. The standard advice has not worked. The conversations haven’t helped. For many people who have lived through them, being weighed, being measured, being told the same thing each time, the conversations have been worse than not happening. They have been actively damaging.

It is worth being clear about what we are arguing and what we are not.

We are not arguing that GPs have failed. The evidence is very specific about where the failure sits: in the design of the consultation, in the tools available within it, and in the structural blind spots of a system trained to treat weight as a behavioural problem when much of it is metabolic, hormonal, environmental, and biographical. The Australian GPs we have spoken with, including the founding GP advisors of Anova, describe the same frustration their patients describe, from the other side of the desk. Fifteen minutes. A complaint that is not the weight, but the back pain or the reflux or the recurrent thrush that is downstream of the weight. The diary already overrun. The note that says advised on diet and exercise, written because there is no other note that fits in the time available.

The medical literature has begun to describe what generations of patients have been telling their doctors. A 2023 systematic review of 32 qualitative studies on weight stigma in healthcare found that patients in larger bodies receive less time per consultation, less patient-centred communication, and less education about their own care than thinner patients with the same presenting complaints. A 2025 cross-sectional study of more than 3,200 patients at a US academic medical centre found that around 1 in 4 women with class 3 obesity had delayed or cancelled medical care specifically because of weight-related stigma in previous appointments. A 2021 study of nearly 14,000 adults across six countries, including Australia, found that weight stigma in healthcare is a robust international pattern, not a local one.

The patient quoted in a 2015 BMJ piece, writing in her own voice, described being seen as a fat person first and an individual second. Whatever the GP’s actual view, this is the view the patient takes home. And the patient’s view is what determines whether they come back for the next appointment, the next screening, the next conversation.

If any of this lands as familiar, if you have felt seen as a number on a scale before being seen as a person, if you have left appointments having been advised on something you didn’t ask about, you are describing a pattern the data now confirms. It is not unusual. It is not your sensitivity. It is happening to a great many people, and it is making the underlying problem worse rather than better. That recognition is itself the first useful piece of information.

What gets called a willpower problem is, in most cases, a system that does not have the time, the tools, or the structural posture for the actual conversation. The science of how weight is regulated has moved a great distance over the last fifteen years. The clinical consultation has, for understandable reasons of system design, not moved with it.

Three things have shifted in the science that matter for any conversation about weight, and that the standard advice has not caught up to.

The first is the recognition that weight is not, in any useful sense, a willpower problem. The biological systems that regulate appetite, energy expenditure, fat storage, and insulin sensitivity are exquisitely tuned and powerfully homeostatic. They evolved in an environment of intermittent food scarcity. They operate now in an environment of constant, engineered, hyperpalatable food abundance. The mismatch is structural. Tim Spector, the King’s College London epidemiologist behind the ZOE personalised nutrition program, puts it this way: the calorie-counting model that has dominated weight advice for fifty years is technically correct and practically useless, because it ignores how the calories themselves are processed, absorbed, and used. The same number of calories from a bowl of beans and a soft drink behave differently in the body. The advice to count them misses the relevant variable.

The second is the recognition that exercise has been substantially over-sold as a weight-management lever. The long-term studies are unambiguous. Exercise has powerful effects on cardiovascular health, mental health, sleep, mood, cognition, longevity, and quality of life. Its effect on weight, used as an intervention on its own, is small. Most people cannot exercise their way out of a poor metabolic environment, and being told to is one of the more discouraging experiences in the standard advice repertoire, because the failure is interpreted as personal rather than mechanical.

The third is the recognition that, for many people, the structural and environmental factors driving weight are not within their day-to-day reach. Ultra-processed food is engineered to override satiety. Sleep deprivation is a strong, bidirectional driver of metabolic dysfunction, and most adults are sleep-deprived. Chronic stress, including the stress of weight stigma itself, raises cortisol and drives visceral fat deposition. Sedentary work, shift work, and screen-saturated evenings shape behaviour at the level of the day in ways that no single appointment can offset.

What weight management actually requires is something closer to a long, slow, multi-pronged clinical conversation (covering nutrition, sleep, stress, movement, mental health, and where appropriate the modern medical interventions that have transformed what is possible) held over months and years, between people who know each other and have time to be specific. It requires the GP, who knows the patient, working in concert with people whose job is the long arc, who are not trying to fit it into a 15-minute window. It requires the assumption, made plainly, that this is a conversation about the structural and biological realities of being a human in a modern environment, not a conversation about the moral character of the person sitting opposite.

That is the conversation Anova is built around. Not as a replacement for the GP relationship, which holds context and trust we cannot replicate — though for many Australians that relationship doesn’t yet exist — but alongside it, with the time, the tools, and the structural posture that the standard appointment cannot supply. We work in co-care with the patient’s GP. We bring the long conversation. We treat the person, not the BMI.

The harder, less-discussed question, the one we will return to in subsequent pieces, is what specifically a better conversation looks like. What it covers. Where the leverage actually is. What the evidence supports, and where it remains uncertain. We will work through those questions one at a time over the coming weeks.

For now, the point is the simpler one. If you have struggled with this, and the clinical conversations have not helped, the failing was structural. The science has moved on. The conversations have not. What you needed was time, tools, and a different posture. That has not been on offer in the standard system. We hope to bring it.
