Imagine this:
You wake up in the morning, skip the cereal, toss out the toast, and dive straight into a sizzling sirloin for breakfast. Sounds like heaven for some, right? Maybe put the steak knife aside while we look into it a bit further. As an Accredited Practising Dietitian (APD) and Nutritionist, I have the evidence-based knowledge to explain the facts about diets like these and highlight the possible risks.
What is the Carnivore Diet?
In simple terms, the carnivore diet is exactly what it sounds like—a diet that consists exclusively of animal products. This means meat, fish, eggs, and, if you’re feeling fancy, a little bit of cheese or butter. Absolutely no fruits, veggies, grains, or legumes.
This diet has gained popularity for its promises of weight loss, improved energy levels, and even relief from certain chronic illnesses. But does it deliver? And more importantly, is it good for you in the long run? The short answer is no. And here are some key reasons why doctors and dieticians don’t recommend this way of eating.
Gut Health Woes
A diet without fibre is like trying to run a marathon without shoes. Sure, you could do it, but why would you want to? Fibre, found in fruits, veggies, and whole grains, is crucial for keeping things moving in your digestive system. Without it, you might end up ‘backed up’—literally. Studies show that fibre plays a big role in gut health, helping to prevent constipation, reduce the risk of colorectal cancer, and even support your immune system.
Nutrient Deficiencies
The carnivore diet is the nutritional equivalent of playing a guitar with only one string. Sure, you can make some noise, but you’re missing out on a full symphony. While meat is rich in certain nutrients like protein, iron, and vitamin B12, it’s completely lacking in others like vitamin C, vitamin K, and magnesium. Vitamins and minerals from plant foods are essential for all sorts of bodily functions—from keeping your bones strong to making sure your heart doesn’t start throwing tantrums.
Heart Health
Most carnivore diets are high in saturated fats, and while the idea that fat is the enemy has been somewhat debunked, it’s still important not to overdo it. A diet that’s heavy in fatty meats can increase your risk of high cholesterol and heart disease. Studies, including those by the Heart Foundation Australia, still show that a diet rich in plant-based foods reduces the risk of cardiovascular diseases.
The Long-Term Outlook
Let’s face it—any diet that cuts out entire food groups is going to leave your body short-changed in some way. Sure, you might lose some weight initially on the carnivore diet, but much of that is likely due to water loss and reduced calorie intake. Long-term, though, there’s not much research backing the idea that an all-meat diet is sustainable, healthy, or safe. In fact, studies show that people who consume a variety of foods, especially those rich in plants, tend to live longer, healthier lives.
So, do you have to rule meat out altogether?
Look, I’m not here to tell you to give up your weekend BBQ?. Meat can absolutely be part of a healthy, balanced diet. But the keyword here is balance. Going all-in on meat might seem like a fun challenge (or an excuse to order steak for breakfast), but it could lead to some serious health issues down the track.
So, next time you’re feeling tempted by the latest diet craze, just remember: Your body is like a finely tuned machine. And to run smoothly, it needs more than just one type of fuel.
