What you really need to know about Ozempic – and how it impacts your relationship with food
Dr Emma Beckett, a food and nutrition scientist , understands Ozempic like few other people. As well as being an expert on how Ozempic changes a person's relationship with food, she has first-hand experience of taking the controversial drug. 'I am a food nutrition scientist and have five degrees on related subjects,' says Dr Beckett , food and nutrition scientist at Food IQ global and adjunct senior lecturer at UNSW. 'I know what to eat for good health. I have just always been a larger person. I am what the fat community refers to as 'small fat'.'
Dr Beckett, who has a family history of cardiovascular disease, tells SBS that when Ozempic came out she was intrigued by its scientific workings as a weight loss drug. "I thought 'let's see how it works'. So I actually tried Ozempic quite early on [around three years ago]." She says she took Ozempic for around four months. During that time, the injections made her "feel less hungry". In that sense, Ozempic did the job it was created to do. 'Ozempic impacts that part of the brain that tells us that we're hungry," Dr Beckett explains. "It slows down how quickly the food we eat moves through our gastrointestinal tract. This helps to make us feel fuller for longer. Ozempic also impacts our insulin signalling pathways. Insulin gets released after we've eaten to help our body utilise energy.' Studies confirm that Ozempic also changes our eating behaviour by reducing the food noise that influence a person's eating habits. People who take the GLP-1 agonist become more in tune with their hunger and satiety and less influenced by emotional, situational, and external sensory cues.
Ozempic impacts that part of the brain that tells us that we're hungry. However, she did experience one major impact which counts as a negative. 'Ozempic reduced my diet quality and didn't improve my relationship with food at all.' She reports that a lack of appetite reduced her interest in eating fruits, vegetables and whole grain foods. Her dairy and protein consumption also declined while on Ozempic. She also felt "numb" and indifferent about food.
A study from the University of Pennsylvania shows that a GLP-1 agonists like Ozempic (or Wegovy) depresses the perception of our five basic taste qualities, therefore changing how we react to dishes we previously thought were tasty. It also reveals that side effects like nausea are experienced more by people who have better taste and smell, due to the impact the drug has on our perception of taste. 'I started thinking, 'this drug may make me slimmer over time but at what cost?' I wondered if I was trading off a heart attack for brittle bones because my diet quality was declining,' Dr Beckett says. She has since stopped taking Ozempic after the first few months, and has not returned to taking the medication since.
Victorian-based GP, Dr Michael Mrozinski says there's no way to predict how Ozempic will make you feel or work on your body until you start taking it. 'Weight loss is really just a trial and error because, genetically, everybody's response to food is different,' Dr Mrozinski says . 'In people with obesity, we know that there is a dysregulation of specific hormones like GLP-1 and how they interact with the brain. What will work for one person to lose weight will certainly not work for someone else because our brains, bodies and hormones are all so different.'
He explains that a person's response to Ozempic and the side-effects experienced may have to do with genetic variations in receptors related to hormones. 'These genetic variations are the reasons why some people maintain a healthy weight range and other people are obese in the first place. 'So when people take Ozempic, some will lose a small amount of weight and won't get any side effects, while others will be 'hyper-responders' who get really good weight loss benefits but also experience a lot of side effects.'
Dr Beckett agrees that drugs like Ozempic will work for a proportion of the population if used holistically and 'correctly'. There's just no way of knowing who it will work for, or how, in advance. She warns that some people who take Ozempic may lose interest in consuming the dishes of their culture and crave bland foods. 'Food isn't just fuel," she says. "A person's diet should be quality as well as quantity. Everyone deserves to enjoy the food on their plate and maintain their cultural connection to it, whether it's a person who is of a higher or lower weight.' 'To use Ozempic 'correctly', you need to take the drug and access dietary, social and cultural support at the same time, so you can maintain or develop a positive relationship with the foods you eat – and not just focus on the amount of foods that you eat,' she says. Dr Mrozinski also says that correct use should always go hand-in-hand with quality medical and dietetic supervision. He also stresses that Ozempic should not be prescribed to people who are a healthy weight or underweight.
You need to take the drug and access dietary, social and cultural support at the same time. 'I'm sure there are some people who still manage to get access to it who shouldn't,' Dr Mrozinski says. 'I certainly wouldn't be prescribing it for anyone who was just wanting to lose a little bit weight for a holiday or upcoming event. That's just inappropriate.' Currently in Australia, Ozempic may be prescribed by a doctor if a person is overweight or obese due to biological, genetic or health factors and at risk of developing type 2 diabetes or other life-threatening medical issues in the future. 'I don't want people to view Ozempic as just a weight loss medication,' says Dr Mrozinski. 'If you think like that, you may put the weight back on again once you stop taking it. I want people to view Ozempic as an opportunity to holistically change their diet and lifestyle, with support.
'I want people who take Ozempic to make small dietary and lifestyle changes when they start taking the drug and then increase them with time." Most importantly, Dr Mrozinski wants everyone who takes Ozempic to learn how to be more in tune with their body. 'If Ozempic completely suppresses your appetite and you're not eating much, you're going to experience nutritional deficiencies and other side-effects. So listen to your body and work with your doctor and a dietitian to determine the right dose for you that helps you to lose weight slowly. 'That will always be the healthier and more sustainable way to move forward.' Watch now Health and Wellbeing Australia

US Army sergeant shoots 5 fellow soldiers at Fort Stewart army base in Georgia
An Army sergeant has opened fire at a military base in Georgia, shooting and wounding five soldiers and prompting a brief lockdown at one of America's largest Army bases, officials have said. The US Army identified the suspected gunman behind the shooting at Fort Stewart as 28-year-old soldier Sergeant Quornelius Radford. Brigadier General John Lubas, the commander of the 3rd Infantry Division, told reporters that Sergeant Radford appeared to use a personal handgun at his workplace, and described the wounded soldiers as Sergeant Radford's co-workers. The gunman was now in custody, he added. Soldiers in the area who witnessed the shooting "immediately and without hesitation" tackled the shooter, Brigadier General Lubas said. The Army said it was still unsure why Sergeant Radford opened fire at his five fellow soldiers, who were in stable condition, adding it was still investigating the shooting. The injured were treated and then moved to Winn Army Community Hospital, base officials said in a Facebook post, adding there was no threat to the community. Some of the wounded were also taken to Memorial Health University Medical Center in Savannah, said spokesperson Bryna Gordon. The hospital is the top-level trauma centre for coastal Georgia. The Army would not release names of those wounded pending notification of family members and would not speculate on motive, Lieutenant Colonel Angel Tomko said at a news conference. Governor Brian Kemp wrote on X that he and his family were "saddened by today's tragedy" at the base. "We are keeping the victims, their families, and all those who answer the call to serve in our hearts and prayers, and we ask that Georgians everywhere do the same," he added. President Donald Trump had been briefed on the shooting and was monitoring the situation, White House press secretary Karoline Leavitt said on X.

Gymgoer almost dies after common post-workout habit
A doctor has warned of a 'shower mistake that could happen to anyone' after a young man hit the gym and 'almost didn't survive'. Dr Aditj Dhamija, a GP in India, shared a case involving a regular gymgoer who collapsed after a jumping into a hot shower immediately after an intensive workout. But the regular post-gym habit put him in intensive care, with the doctor claiming 'the patient barely escaped death'. 'A 24-year-old man hit the gym like every day … but when he didn't come out of the bathroom for 30 minutes, the door had to be broken down,' Dr Dhamija explained in an Instagram video. 'He was found unconscious on the floor, pulse barely there.' Once in the emergency room, he was put on a ventilator. Dr Zac, a leading Australian GP, notes that in most cases, it's not dangerous to shower after exercise. 'However, it can be risky if you jump straight in after intense exercise,' he told 'When you finish working out, your heart rate is high, blood vessels are dilated, and your body is cooling itself. 'Very hot water at this point can further dilate blood vessels and cause a sudden drop in blood pressure, which may lead to dizziness, fainting, or – in rare cases – collapse.' He recommends waiting five to ten minutes to let your body cool down before turning on the hot water. He also mentions that, when done carefully, hot showers can actually help recovery. 'They relax tight muscles and boost blood flow, which can be helpful later in the day. But they might also prolong inflammation and direct more blood to the skin instead of the muscles, possibly slowing recovery if used immediately,' he said. He suggests opting for a cold or lukewarm shower straight after a workout, as these can help lower core temperature and reduce inflammation. Sports medicine research shows that cooling methods like cold water immersion are most effective for muscle recovery, but shower temperature is still worth considering. In his video, Dr Dhamija also warned to look out for signs that something's wrong if you're getting into an overly hot shower. 'Don't ignore light-headedness or dizziness,' he said, and 'Don't forget to hydrate properly.' He also advised rehydrating well after exercise, and if you feel faint, lie down and elevate your legs. 'Fitness should make you stronger — not take you closer to death.'

New research links hundreds more deaths to major bushfires in Los Angeles and Hawaii
Poor air quality, health care delays and a surge in suicides have been blamed for hundreds of deaths following large-scale bushfires in Los Angeles and Hawaii. That's according to three separate reports released this week by the scientific journal JAMA. The number of suicide and overdose deaths in Hawaii jumped by 46 per cent in August 2023, when fires spread across the island of Maui, according to one report. Those fires burned more than 2,200 structures and killed more than 100 people directly. Lung problems and mental health issues also increased following the disaster, according to separate research. A third paper looking into the Los Angeles wildfires in January found 440 deaths — compared to the official death toll of 30 — could be attributed to the destruction. Researchers from Boston University's Department of Global Health compared the expected weekly death rate for LA to the actual tally. They found the additional deaths likely reflected a combination of factors, including "increased exposure to poor air quality" and health care delays. The Palisades fire in California sparked up during heavy winds on January 7, ripping through the affluent LA neighbourhood. It killed at least 12 people and damaged nearly 8,000 homes, businesses and other structures. The same day, a second fire started in the eastern suburb of Altadena, killing another 17 and destroying or damaging more than 10,000 buildings. Other fires ignited across the area in the following days and weeks. The new study out of Boston University looked at the excess deaths in Los Angeles County from January 5 to February 1. For each week, they compared the expected deaths and the actual number of deaths in the area. The weekly deaths "consistently exceeded" the expected amount — with a total 6,371 deaths in that time compared to the expected 5,931. This meant, they concluded, an excess of 440 people died during the wildfires. "The findings … highlight the need for improved mortality surveillance during and after wildfire emergencies." Co-author Dr Andrew Stokes said researchers had suspected the official death toll after the fires was likely a "severe under-count". "We used an excess mortality modelling framework to obtain estimates of the wildfires on all-cause mortality," he said. "[This included] deaths associated with exposure to toxic chemicals in wildfire smoke and deaths associated with health care interruptions and delays. "These gaps are commonly found in research comparing mortality estimates to official death tolls associated with natural disasters. He added future research should investigate additional cause of death data, hospital records and administrative claims to narrow down the specific reasons for extra deaths. In August 2023, a series of wildfires broke out across the island of Maui in Hawaii. Like the Los Angeles fires, these were sparked by dry conditions and extreme winds. Four separate fires burned for weeks across the area, killing at least 102 people and destroying thousands of homes. In the wake of the fire there was also an increase in calls to Hawaii's suicide and crisis helpline, according to research out of New York University. There were 13 deaths from overdose and suicide in Maui in August 2023, and 59 in non-Maui counties of Hawaii, the highest in a 120-month time period and a 46 per cent increase on all other months. The jump in numbers was not sustained throughout the following four months. "Results show that the 2023 Maui wildfires had immediate effects on suicide and overdose deaths in Maui and across the Hawaiian islands broadly," the report said. "[The statewide rate] suggests that direct exposure to the wildfires may have increased risk of suicide and overdose death among Maui residents who migrated to neighbouring islands during or after the fires. "Indirect exposure to the wildfires [like] concerns for loved ones may have also increased the risk of death from these causes on neighbouring islands." Their report noted however that only four months of post-wildfire death data was available, adding their findings were limited by lack of information on exact dates of death and migration data. The research was supported by the National Institute on Minority Health and Health Disparities. The second Maui report found there was an increase in economic hardship, food insecurity, and lack of healthcare in the wake of the fires. Almost a quarter of the 1,043 people surveyed by researchers at the University of Hawaii were experiencing very low food security. This was more than double the pre-disaster rate. "Mental health burdens were also substantial, with depressive symptoms exceeding historical pre-wildfire estimates. "Pre-wildfire mental health prevalence in Maui County indicated baseline depression rates of 30 per cent, low self-esteem prevalence of 13 per cent, and suicidal ideation in less than 1 per cent of the population." The survey found 4.6 per cent of participants experienced suicidal ideation, 26.1 per cent reported low self-esteem and 49.4 per cent showed "clinically meaningful depressive symptoms". Their report was backed by the Hawaii Community Foundation, Kaiser Permanente, the State of Hawaii and a grant from the National Institute of Health. All three reports published by JAMA were peer-reviewed. Andrew Gissing, chief executive of Natural Hazards Research Australia, said the reports were important, but not surprising. "What you're seeing in terms of those excess death statistics, we've seen that here in Australia as well," he told the ABC. "Post-Black Summer, there's been some similar research done [which found] there were excess fatalities due to wildfire smoke in the hundreds. "The implication for wildfire management across the world is that as much as we concentrate on the actual fighting of these fires, we need to make sure that we're very much focused on the public health impacts there as well. "That messaging to stay indoors, to minimise exposure to bushfire smoke [is] obviously really key during these events." The research about ongoing mental health impacts, he said, could be attributed to the "long tail of disasters". "We often measure disasters by their direct impact, insurance losses or how many people immediately were injured or killed," he said. "What we see are these longer tail impacts due to the trauma and the physical impacts of those events." Dr Sonia Angell, from the Hopkins Bloomberg School of Public Health said the research highlighted the failure of current responses to extreme weather events. "Each of these studies provides a unique example of how [emergency] health measurements … such as direct fatalities do not sufficiently capture the full health impact of wildfires," she said. "Climate health impacts can occur long after an event or be unassociated with extreme events." The Australasian Fire and Emergency Services Authorities Council (AFAC) said in its latest bushfire outlook there was an "unseasonable bushfire risk" this winter. The council noted a heightened risk of fire in large parts of Victoria and in southern areas of South Australia. "[There's] this concept of worsening natural hazard risk that we're facing in Australia," Mr Gissing said. "That's been driven by climate change increasing the frequency of extremes, but it's also due to our own decisions about where we choose to live and build our homes into the future as well. "That means we're seeing some people being more frequently exposed [to disasters] than others, particularly in those high-risk areas. "And with each extreme, we know the compounding trauma of that only makes things worse.'
