The Rise of the Modern 'Hustle' Diet and Its Impact on Our Health


 It's no secret that our diets aren't great. With the world's population set to hit 9 billion by 2050, and unhealthy food environments becoming the norm, it's no wonder unhealthy diets are the main preventable risk factor for disease both globally and here in Australia. But how did we get here?

According to data from the Australian National Health and Medical Research Council, less than 7% of Aussies are eating in line with the recommended Australian Dietary Guidelines. It's no surprise then that we're seeing rates of obesity on the rise, with 63% of adults and 25% of kids now overweight or obese.

The "hustle" culture has had a significant impact on our diets. With longer working hours and constant connectivity, convenience foods have become a go-to for many of us. But this eat-and-run diet, filled with unhealthy options, can have a major impact on our physical activity levels, body composition, life expectancy, and the risk of diseases such as heart attacks, strokes, and cancer. But it's not all bad news, we can take control of our health and our future by making better food choices.

In recent years, there's been a growing awareness and push towards healthier, more sustainable options, like the "green movement" that's drawing people back to nature and traditional, organic foods. There's more education now on the health benefits of "superfoods", which are foods that pack a lot of nutrition in while having hardly any calories. These foods are often high in antioxidants, vitamins, and minerals and are mostly plant-based. We're starting to realize that if we want to be healthy, we've got to start with what we're putting in our mouths


The Rise of the Modern ‘Hustle’ Diet

It feels like unhealthy food is being thrown at us from all directions these days. From the ads on our morning news shows, to billboards on the way to work, and even on government buses and our social media feeds. The constant bombardment of marketing and temptation is overwhelming.

With our busy lives, it's getting harder to take the time to think about whether the food we're eating is good for us. Globalization has opened up more options at lower costs, like ultra-processed "junk foods" that are high in calories but low in nutrition. Studies have shown that eating junk food can lead to a lot of health problems. But it's important to remember that you're in charge of your own health, and you need to make sure you're taking care of yourself. Unfortunately, the laws and regulations in place aren't as effective as they should be. In many countries, health issues like heart disease, obesity, diabetes, food poisoning, dehydration, and arthritis are on the rise, and it's because of unhealthy foods like junk food, processed foods, and high-fat diets. Even though public health programs in the 80s and 90s helped reduce deaths from heart disease, they also led to people eating too many carbohydrates and contributed to the obesity crisis that many people in Western countries are facing today.

Empty calories:

"Empty calories" refers to foods that provide energy in the form of calories, but don't offer much in the way of nutrition. According to clinical dietitian, Leslie Ramirez, all foods contain calories, and your body uses them for energy, stores them as glycogen or turns them into fat depending on how many you consume. Even though some foods like certain vegetables and fruits are low in calories, nothing we eat is completely calorie-free (except for water and artificial sweeteners).

Common foods and drinks consumed in Australia that are high in empty calories include:

  • sugary drinks like sports/energy drinks, soft drinks and alcohol convenience and fast foods
  • pastries, white bread, pizza, and pasta dishes with butter, cream, or cheese sauce
  • Sausages, chips and processed breakfast cereals.

These foods will give you a quick energy boost, but they don't provide any other benefits like building muscle, providing vitamins, making you feel full, or anything else.

One of the big problems with empty calories is that they can be easy to consume in excess without even realising it. They're not just found in obvious foods like desserts, they're also hidden in things like drinks, snacks, breakfast foods marketed as healthy options. Because of this, they're often referred to as "stealth calories." It's important to remember that overeating any type of food can be unhealthy, but overeating foods that don't have any health benefits can have lasting consequences including weight gain and on the flip side, making it more difficult to lose weight. These empty calories are easily digested by the body, so they won't keep you feeling full for very long and will keep you craving more and more.

Sugar Addiction:

It's no secret that too much sugar can be bad for our health. But did you know that according to recent data from the Australian Bureau of Statistics (ABS), more than half of Australians are consuming more sugar than is recommended by the World Health Organisation? Not only can consuming too much sugar lead to weight gain, but it can also cause cognitive problems and even addiction. In fact, a peer reviewed study on rats has demonstrated that sugar can be as addictive as illicit drugs (Avena, Rada & Hoebel et al,.2007).

Not only is sugar harmful to your brain, but it can have serious lasting impacts on your whole body. If your parents were anything like mine, you would have got the same sermon around limiting lollies to prevent cavities and tooth decay, but the white stuff can also contribute to weight gain and an increased risk of developing Type 2 Diabetes. When we consume too much sugar, it can mess with a hormone called insulin, which is responsible for regulating our blood sugar levels. When insulin is overworked, it can lead to insulin resistance, which can eventually lead to Type 2 Diabetes, a growing epidemic across western nations including Australia. So a tip is to keep an eye on our sugar intake and make sure you’re not overdoing it.

Mass Consumers:

Around the world, the way we eat is changing quickly. Even the most common foods are being replaced with ‘on trend’ diets. This evolution can be driven by many factors including income, knowledge and influence. In countries like Australia, the cost of food is particularly affected by things like our geography, urbanisation and marketing. It is a sad reality that processed junk foods are still far cheaper than healthy, organic whole foods, which is a key barrier for many to make the change.

In developing countries, modern retailers like supermarkets and fast-food restaurants are becoming more popular and accessible, often at the expense of traditional food markets and stores. This increase in access, eventually leads to an increase in consumption and calorie intake. Research around trends in these developing countries has shown that our young people are the main consumers of these ‘hustle’ junk foods with empty calories.

With the population expected to reach 9 billion by 2050, unhealthy diets are now clearly the main preventable risk factor to increasing disease and illness globally and in Australia. The Australian National Health and Medical Research Council defines unhealthy "discretionary" choices as foods and beverages high in saturated fat, added sugar, and salt. According to data from the Australian Health Survey, less than 7% of Australians consume diets that are in line with the recommendations of the Australian Dietary Guidelines (ADGs) 2013. Equally as alarming, at least 35% of the energy intake of Australian adults and at least 39% of the energy intake of children now come from these unhealthy "discretionary" choices. This concerning trend is a key contributor to 63% of Australian adults and 25% of Australian children being overweight or obese.

As someone who is passionate about healthy living and outcomes for all Australians, this does NOT sit well with me. Whilst the government has a serious role to play, it is ultimately up to each individual to become more educated and aware of the damage they are doing to their bodies. As the ancient Greek physician Hippocrates once said so well, "Let food be thy medicine and medicine be thy food”.

The real impacts of the ‘hustle’ lifestyle.

We are living in a new age, where we no longer simply reference ourselves to family, friends and locals but the whole world. Keeping up with the Jones’s just became keeping up with the Kardashians in the blink of an eye. Wanting ‘more’  has become the obsession of so many caught in the ‘hustle’ lifestyle that we can’t see what it is costing us to fund it. Maybe it’s working more overtime during the week, maybe picking up a day over the weekend, maybe starting a side hustle, whatever it is, it is costing us two things that are very important to you, your time and sleep. Science shows that not getting enough sleep, leads to sleep debt which quickly accumulates, taking a toll on your body and your organs. If you’re anything like me when you're sleep deprived, you're not going to be much fun to be around and you’re definitely not going to be present with your friends or family. In fact research says that there is a very good chance your going to be irritable, sad, drowsy, stressed out, and even sick. Sounds like fun right? Wrong!

Here's how the hustle lifestyle and not getting enough shut-eye is harming your body:


Ever wondered why stress can literally make you feel sick? It's because your emotions can affect your body. Stress isn’t just an emotion, it's a natural physical response to danger. According to Jay Winner, MD, author of Take the Stress Out of Your Life and director of the Stress Management Program for Sansum Clinic, when you're constantly stressed, those physical changes can lead to health problems over time. Stress can make just about any health condition worse. Studies have linked stress to a lot of chronic health issues, like obesity, gut problems, heart disease, diabetes, depression, Alzheimer's disease, asthma and the list goes on. All of these conditions can become riskier and more prevalent when you're under stress.


Stating the obvious but carrying too much weight leads to health problems. Obesity increases your risk for a lot of chronic illnesses, like certain types of cancer, heart disease, stroke, high blood pressure, high cholesterol, type 2 diabetes, sleep apnea, liver and gallbladder disease. Being overweight can also cause joint pain and diseases like osteoarthritis which isn’t fun for anyone having seen some of my family members manage this. Obesity is a costly condition whose association with illness, unfortunately peels years away from your life, leading to many premature deaths. In Australia, the scary truth is 67% of the adult population is overweight or obese, and that number has been rising. The Collective for Action on Obesity, an organisation made up of over 100 groups like Bupa, has recently released a report on updated data and is calling for an immediate action to combat the obesity epidemic.

Depression & Anxiety:

Firstly, it’s okay, not to be okay. There has been a lot of education around depression and anxiety over the last decade which was very much needed and slowly but surely, we are breaking down the stigma to talk about the subject. When you're dealing with a chronic illness, it's not uncommon to feel down. The hard truth is that depression is common among people with chronic illnesses. Just take a look at these stats: if you've got coronary artery disease, but haven't had a heart attack, you've got an 18-20% chance of also experiencing depression. If you've had a heart attack, that jumps up to 40-65%. Even if you've had a stroke, it's still a 10-27% chance. And it's the same story for other chronic illnesses like Parkinson's (40%), diabetes (25%), cancer (25%), and multiple sclerosis (40%).

The 2 million year old de-evolution of processed foods

People have been processing food since they learned how to cook, stretching back some 1.5 million years. It started out as simply adding heat to our catch in prehistoric times, to drying, smoking and salting preservation methods as time went by. Some of the earlier civilizations to advance preservation methods included the Egyptians, who we know even nailed how to preserve themselves! But over time, the reasons for processing food have changed. These days, ultra-processed foods are packed with colours, sugars, salts and preservatives that offer zero nutritional value. We call these foods "junk foods", a phrase coined by Michael Jacobson, the director of the Center for Science in Washington, DC, back in 1972 to catch people's attention. These foods are also low in protein and other important nutrients required to sustain life. These nutritionally worthless foods have sadly become popular in the modern ‘hustle’ diet due to their price, availability, and speed to service.

The truth about the modern processed food industry and have we gone too far?

It's no secret that processed foods aren't as good as the real deal. Even the everyday apples you grab from the produce section have likely been through a few processes before they hit the shelves. There is nothing worse then grabbing an apple that looks like it’s from the garden of eden, taking a big bite only to find it rotting from the core. But if they were using processed foods over a million years ago, why are they worse these days? To answer this question we need to dive a little deeper and look at the difference between different types of processed foods.

Ultra-processed food is made using different techniques and ingredients. These foods are usually ready-to-eat and don't require much preparation. They're designed to make you eat more, so you'll buy more of them (what a business model right). Examples include sugary drinks, sweets, frozen dinners, crackers, chips, cereal, and lunch meats. These types of processed foods are also low in fiber and essential nutrients. Did you know, in Australia, we are eating increasingly more of these nutrient-poor, high-energy meals. In fact, we’ve got one of the highest rates of sales of ultra-processed foods in the world. Another statistic that I drop my head to. According to forecasts, Australians are tipped to drop up to $7.4 billion on fast foods in 2023. Now you can start to see the power of the fast food machine.

Unhealthy diets are a major risk factor for disease globally and in Australia, with busy lifestyles and easy access to convenience foods having contributed to the rise of the "hustle" diet. Thankfully, there is a growing awareness of the importance of healthy, sustainable food choices and the health benefits associated with nutritionally dense superfoods. Read on to find out more about these special foods and how they can significantly impact your life.
