Ingredients of Coke Zero

Understanding the ingredients of Coke Zero is crucial for assessing its compatibility with various diets, including the Carnivore Diet.

Carbonated Water: Water infused with carbon dioxide gas under pressure creates the fizzy texture characteristic of sodas. It is generally harmless and contributes to the beverage's effervescence.
Caramel Color (E150d): This is a typical food coloring made by heating sugar in the presence of acids, alkalis, or salts. It gives Coke Zero its distinctive dark color.
Phosphoric acid: This gives the drink more acidity, which improves flavor and gives it a tangy taste. One of the main ingredients in Coke Zero is phosphoric acid. One 2002 study on human teeth noted phosphoric acid causes mild enamel and tooth erosion. Still, the same 2002 study suggests that citric acid erodes teeth more than phosphoric acid, which suggests that Coke Zero may affect tooth enamel slightly less than Diet Coke.
Aspartame: An artificial sweetener approximately 200 times sweeter than sugar. It is used to provide sweetness without adding calories. While aspartame is calorie-free, some studies suggest it is a synthetic compound that might have adverse health effects, such as impacting insulin response or gut health. Despite having no calories, aspartame can trigger a cephalic phase of insulin release. It may disrupt normal metabolic processes and signals of satiety. This phenomenon may conflict with the goals of a carnivore diet.
Potassium Benzoate: A preservative that keeps fungus, yeast, and bacteria from growing in drinks.
Natural Flavors: A proprietary blend of flavors derived from natural sources to enhance the beverage's taste. The only differences between Coke Zero and the new rebrand Coca-Cola Zero Sugar are minor changes to the natural flavor composition.
Potassium Citrate: Used to regulate acidity and add a tart taste.
Acesulfame Potassium (Ace-K): Another artificial sweetener, about 200 times sweeter than sugar, used to enhance sweetness without adding calories. According to specific research, aspartame and acesulfame potassium are two artificial sweeteners.

What is the Carnivore Diet?

The Carnivore Diet is a highly restrictive way of eating that consists only of animal-based foods. That means meat, fish, eggs, and certain dairy products are allowed, while everything else-including vegetables, fruits, grains, legumes, nuts, and processed foods-is completely eliminated. Unlike other low-carb or ketogenic diets that allow some plant foods, the Carnivore Diet follows a strict zero-carb approach. Although the diet is simple in concept, it’s controversial. While some report life-changing benefits, others experience negative side effects from cutting out plant-based foods. While scientific research on this diet is still limited, there are some potential benefits based on low-carb, high-protein nutrition principles.

Many followers of this diet believe that humans evolved to eat mostly meat, arguing that eliminating plant-based foods can improve digestion, reduce inflammation, and regulate blood sugar levels. The Carnivore plan is often compared to the Ketogenic Diet because of its high-fat, moderate-protein, and low-carb structure, but the biggest difference is that keto allows non-starchy vegetables and plant-based fats, whereas the Carnivore Diet does not.

Potential Benefits of the Carnivore Diet

The Carnivore Diet has gained a loyal following, with many people claiming that cutting out plant foods leads to incredible health transformations.

Weight Loss and Fat Burning: By eliminating carbohydrates, the body switches to burning fat for fuel, similar to the effects of ketosis on a ketogenic diet. Many carnivore dieters experience rapid fat loss, reduced cravings, and better appetite control since protein and fat help keep you full longer.
Reduced Inflammation and Autoimmune Relief: Some individuals with autoimmune conditions, digestive issues, or chronic inflammation report feeling significantly better on the Carnivore Diet. By eliminating processed foods, refined carbs, and potentially inflammatory plant compounds, some people experience relief from symptoms like joint pain, bloating, and skin issues.
Simplicity and Ease: Unlike other diets that require tracking macros, counting calories, or restricting meal timing, the Carnivore Diet is incredibly simple-just eat meat until you’re full. This simplicity can be mentally freeing for people who struggle with complicated meal plans and diet rules.
Muscle Growth and Strength Gains: For those focused on fitness and strength training, the high protein intake on the Carnivore Diet can support muscle growth, recovery, and overall athletic performance. Many bodybuilders and athletes use variations of the diet to boost lean muscle mass while staying lean.

Downsides & Risks of an All-Meat Diet

While the Carnivore Diet has its fans, it's not without controversy. Many health experts warn about the long-term risks of cutting out plant-based foods entirely. While some people may experience short-term benefits, there are several potential nutritional and health concerns to consider before committing to an all-meat lifestyle.

Nutrient Deficiencies and Lack of Dietary Fiber: One of the biggest criticisms of the Carnivore Diet is that it eliminates key nutrients found in fruits, vegetables, and whole grains. While animal products provide protein, iron, and essential fats, they lack fiber, vitamin C, antioxidants, and phytochemicals, which play crucial roles in digestion, immune function, and disease prevention. Fiber, in particular, is essential for gut health, digestion, and maintaining healthy cholesterol levels. Without fiber-rich foods like vegetables, legumes, and whole grains, some people on the Carnivore Diet experience constipation and irregular digestion.
Potential Heart Health Concerns: Another debated topic is the impact of a high-fat, high-cholesterol diet on heart health. The Carnivore Diet is naturally high in saturated fats and cholesterol, primarily from red meat, eggs, and dairy. While some research suggests that dietary cholesterol doesn’t directly contribute to heart disease, other studies indicate that excessive red meat consumption may be linked to increased inflammation and higher risks of heart-related conditions.
Gut Health and Microbiome Disruptions: The human gut is home to trillions of beneficial bacteria that thrive on diverse nutrients, particularly fiber and prebiotics found in plant-based foods. Eliminating these entirely may alter the gut microbiome, potentially leading to digestive issues, reduced bacterial diversity, and long-term health consequences. The Carnivore Diet emphasizes a healthy gut, often achieved through consuming animal products and avoiding processed foods. It impacts the gut microbiota and may cause dysbiosis, an imbalance in gut flora.

Can You Drink Coke Zero on the Carnivore Diet?

Drinking Coke Zero on the carnivore diet is always a big controversial topic. So, what exactly can you drink Coke Zero on the Carnivore diet? The short answer is technically yes, but it’s not recommended. From a strict Carnivore perspective, any drink containing artificial sweeteners or chemical additives (like aspartame or caramel color) is not allowed, as it’s not an animal-based or nutrient-dense product. However, some relaxed or modified Carnivore dieters allow occasional sugar-free beverages like Coke Zero, especially during the transition phase when sugar cravings or social situations make it hard to avoid such drinks altogether.

Some people say it is okay to drink because it has no sugar or carbs. They believe it can help satisfy a craving for something sweet without breaking the diet. Some users say it helps them stay on track with their diet by giving them a treat they can look forward to. On the other hand, many users are concerned about the artificial ingredients in Coke Zero. They worry these ingredients could cause harm to their health over time. A few users mention that Coke Zero can cause negative effects like bloating, digestive issues, or headaches. They think the artificial sweeteners might have an impact on mental health and overall well-being. Overall, opinions on Coke Zero among carnivore diet followers are divided.

Coke Zero and Its Impact on Health

Coke Zero is often marketed as a healthier alternative to regular soda due to its lack of calories and sugar. However, its impact on health is complex and multifaceted. Here’s a look at how Coke Zero can affect weight loss, gut health, insulin levels, and hydration.

Weight Loss: As you know, Coke Zero contains no calories. So, it can be an alternative to sugary drinks for those trying to reduce calorie intake and lose weight.
Insulin Levels: Coke Zero doesn’t contain sugar and thus doesn’t raise blood glucose levels. However, some evidence suggests artificial sweeteners might still trigger an insulin response in some individuals. The release of insulin could affect weight management and complicate insulin control for those on a strict diet. The Carnivore Diet, being low in carbohydrates, typically helps maintain stable blood glucose and insulin levels.
Hydration: Coke Zero is not a good choice for hydration. Its caffeine can have a mild diuretic effect, potentially increasing urination and affecting hydration. On the Carnivore Diet, being well-hydrated is essential, mainly because the high protein content may cause the body to require more water.

Potential Downsides of Coke Zero

Tooth Erosion: Similarly to regular soda, drinking diet sodas like Coke Zero is associated with an increased risk of tooth erosion. An older study from 2015 observed that Coca-Cola Light (Diet Coke), which differs from Coke Zero only in that it contains both phosphoric and citric acid, caused enamel and tooth erosion in freshly extracted cow’s teeth in just 3 minutes. Diet Coke had less erosive effects than other beverages, such as Sprite, orange juice, and apple juice.
Risk of Diabetes: Coke Zero is sugar-free. However, the sugar substitutes it contains may not necessarily be a better option for people looking to reduce their risk of diabetes. A large 2023 study involving 105,588 participants with a follow-up of 9.1 years suggests that consuming non-nutritive sweeteners is associated with an increased risk of developing type 2 diabetes. A 2024 review of research suggests non-nutritive sweeteners may negatively affect the gut microbiome, or the helpful bacteria that live in your gut and aid digestion, potentially affecting metabolic health and contributing to diabetes risk and worse outcomes for people with diabetes.
Other Health Issues: Artificially sweetened beverages like Coke Zero have been linked to other health issues, including:
- Increased risk of heart disease: An observational study found a link between artificially sweetened beverages and an increased risk of heart disease among women with no prior history of heart disease.
- Increased risk of kidney disease: Soda’s high phosphorus content may damage kidneys. A 2017 study noted that those who drink more than 7 glasses of diet soda per week nearly double their risk of kidney disease.
- Could alter your gut microbiome: Artificially sweetened beverages may alter your gut microbiome, potentially negatively affecting blood sugar management.

Better Alternatives to Coke Zero

If you’re looking for alternatives that align better with the carnivore diet, consider these options:

Water (Still or Sparkling): Plain water is the number 1 best drink on any diet, especially Carnivore, no matter what version or stage you are at. You can drink filtered or mineral water, and even carbonated water, as long as it contains no flavorings or additives. Natural sparkling water, like San Pellegrino or Gerolsteiner, can also help boost mineral intake.
Bone Broth: Homemade bone broth made from beef, lamb, or chicken bones is highly nutritious and supports joint, skin, and gut health. It’s rich in collagen, minerals, and amino acids.
Electrolyte Drinks: Mineral-rich water with added sea salt or animal-based electrolytes (like magnesium or potassium from animal sources) helps maintain hydration. Just be sure it has no sweeteners or flavorings.
Fat Broth: One of the most nutritious sugar free drinks on Carnivore Diet is a warm cup of beef tallow or butter melted into hot water, sometimes called a fat broth. It’s satiating and great for energy and mental focus during fasting or early mornings.
Animal-Based Protein Shakes: Protein shakes aren’t essential on a Carnivore Diet because you're already getting plenty of protein from meat. But for athletes, busy people, or those who struggle with chewing or appetite, animal-based protein powders can be helpful.

There are also alternative brands for sugar-free sodas:

Zevia Cola: is a popular brand known for its zero-calorie sodas that are sweetened naturally with stevia. The natural sweetener, stevia, does not affect insulin levels and is not derived from sources that are restricted in the carnivore diet.
Virgil's Zero Sugar Cola: is crafted by Virgil's, a company renowned for its commitment to producing premium, all-natural sodas. Virgil's Zero Sugar Cola contains no added sugars or artificial sweeteners. These natural sweeteners are permissible on the carnivore diet as they do not contribute to carb intake or affect insulin levels.
Boylan Bottling Co.: Boylan Bottling Co. has a long history of producing craft sodas using high-quality ingredients. Boylan Diet Cola is free from sugars and artificial sweeteners commonly found in regular sodas.
Pepsi Zero Sugar: formerly known as Pepsi Max, is a widely recognized product from PepsiCo.
