Can I drink coke zero on a carnivore diet? The surprising truth about artificial sweeteners and gut health

4 min read

According to a 2022 study published in Cell, artificial and natural sweeteners can alter the makeup of healthy people's gut microbiomes and disrupt metabolic health. This fact is crucial for anyone on a restrictive eating plan, raising a critical question for many followers of a meat-centric lifestyle: 'Can I drink coke zero on a carnivore diet?'

Quick Summary

This article examines the conflict between consuming Coke Zero and adhering to a carnivore diet. It explores how artificial sweeteners and non-animal ingredients can disrupt ketosis, harm gut health, and undermine the core goals of this elimination diet.

Key Points

  • Strict Carnivore Rules: Coke Zero is not allowed on a strict carnivore diet because it contains artificial, non-animal ingredients like aspartame, phosphoric acid, and caramel color.

  • Ketosis Interference: Artificial sweeteners in diet soda might trigger a cephalic phase insulin response in some individuals, potentially affecting the body's ketosis, even with zero carbs.

  • Gut Health Impact: The additives in Coke Zero can disrupt the gut microbiome, which is a key area of focus for healing on a carnivore diet.

  • Perpetuating Cravings: Consuming artificially sweetened drinks keeps the brain accustomed to sweet flavors, hindering the reset process aimed at eliminating sugar addiction.

  • Relaxed Approach vs. Strict Adherence: The acceptance of Coke Zero depends on whether a follower is strict or follows a more relaxed version of the diet, where occasional, non-compliant items are permitted.

  • Better Beverage Options: Optimal beverage choices for the carnivore diet are plain water, sparkling water (unflavored), and bone broth.

  • Individual Variability: The impact of artificial sweeteners can vary by individual due to differences in gut microbiome composition.

The Carnivore Diet's Principles and Processed Products

The carnivore diet is an elimination-style eating plan focused exclusively on animal products, such as meat, fish, eggs, and some low-lactose dairy. Its followers eliminate all plant-based foods, processed items, and sugars. The diet operates on the principle that restricting food intake to animal sources can reduce inflammation, stabilize blood sugar, and address various health issues. Given this, the compatibility of a highly processed, chemical-laden beverage like Coke Zero is immediately questionable.

What is in Coke Zero?

To understand why Coke Zero is a contentious topic on a carnivore diet, one must examine its ingredients. The list reveals a cocktail of chemicals and plant-derived compounds that are not permitted on a strict carnivore protocol.

  • Carbonated Water: While water is a core component of any diet, the other additives are the issue.
  • Caramel Color: A food additive used for coloring, not an animal product.
  • Phosphoric Acid: An inorganic acid that is not derived from animal sources.
  • Artificial Sweeteners: The primary flavor comes from aspartame and acesulfame potassium (Ace-K). These are synthesized chemicals, not animal-based nutrients.
  • Natural Flavors: This ambiguous term can include plant extracts, which are strictly prohibited on a carnivore diet.
  • Potassium Benzoate: A preservative used to protect the taste, again a non-animal additive.

Artificial Sweeteners and Insulin Response

One of the main goals of the carnivore diet is to achieve a state of ketosis by eliminating carbohydrates and sugar. While Coke Zero contains zero sugar and zero calories, the artificial sweeteners within it can be problematic.

Some research suggests that even without sugar, the sweet taste of non-nutritive sweeteners can trigger a 'cephalic phase insulin response,' where the brain signals the pancreas to release insulin in anticipation of glucose. This effect is highly individualized and doesn't happen to everyone. In sensitive individuals, even a small insulin spike could potentially interfere with the body's fat-burning state of ketosis, which is a key component of the carnivore diet.

The Impact on Gut Health

Many individuals adopt the carnivore diet to heal their gut microbiome and alleviate digestive or autoimmune issues. The reliance on animal-based foods and the elimination of inflammatory plant compounds is intended to restore gut health.

However, artificial sweeteners have been shown to have a negative impact on the gut microbiome, altering the balance of beneficial and harmful bacteria. Studies have indicated that some sweeteners, particularly sucralose and saccharin, can disrupt gut flora, potentially leading to dysbiosis, which is an imbalance of gut bacteria. This disruption can undermine the very gut-healing benefits the diet is meant to provide.

Cravings and Taste Dependency

Another goal of the carnivore diet is to reset taste buds and eliminate dependence on sugary or sweet flavors. By consuming Coke Zero, which uses potent artificial sweeteners, individuals risk keeping their craving for sweetness alive. The brain's reward pathways are activated by the sweet taste, regardless of whether it's from sugar or a substitute. This can make it harder to sustain the diet in the long term, potentially leading to non-compliance and a return to less healthy eating habits.

The Strict Carnivore vs. Relaxed Carnivore Approach

The ultimate decision of whether to drink Coke Zero hinges on how strictly one follows the carnivore diet. The carnivore community is not monolithic, with some adhering to a 'nose-to-tail' philosophy and others being more flexible.

A Comparative Look at Coke Zero on Carnivore

Aspect Strict Carnivore's View Relaxed Carnivore's View
Ingredients Prohibited due to non-animal components like artificial sweeteners, phosphoric acid, and caramel color. May tolerate occasional consumption, especially during a transition phase or in social situations.
Ketosis Potential risk of an insulin response, which could interfere with fat adaptation and metabolic goals. Minimal risk, as it contains zero carbs and will not raise blood glucose. The impact is seen as less significant than consuming real sugar.
Gut Health High risk of disrupting the delicate balance of the gut microbiome with artificial additives. Potential risk, but viewed as a manageable side effect if consumption is infrequent.
Cravings Hinders the process of resetting taste buds and overcoming sweet flavor dependency. Helpful for managing cravings, providing a satisfying alternative without derailing carb intake.
Primary Goal Healing and elimination; purity of diet is paramount. Any non-animal product is seen as a deviation. Weight loss or appetite control; pragmatic choices are sometimes made for adherence.

What to Drink Instead of Coke Zero

For those who wish to avoid the potential pitfalls of Coke Zero and stay true to the carnivore ethos, several alternative beverages are available:

  • Plain Water: The simplest and most fundamental choice. Still or sparkling water is perfectly acceptable.
  • Bone Broth: Rich in electrolytes and nutrients, bone broth is a compliant and nourishing beverage.
  • Plain Sparkling Water: As long as it is unflavored and contains no additives, it is a safe choice.
  • Black Coffee or Tea: While technically plant-based, many relaxed carnivores permit these in moderation. However, they are not part of a strict protocol.

Conclusion: The Final Verdict

Ultimately, the question of 'can I drink coke zero on a carnivore diet?' depends on your goals and how strictly you define the diet. From a strict carnivore perspective, the answer is a clear no. The artificial sweeteners, caramel color, and other additives conflict directly with the principle of consuming only animal products. These ingredients may also cause unwanted side effects like gut microbiome disruption, triggered cravings, and a potential, albeit minimal, insulin response in some individuals.

For those following a more relaxed version, an occasional Coke Zero might seem harmless, especially if the primary goal is weight loss and avoiding carbs. However, even in this case, it’s worth considering whether keeping a sweet taste in your diet is undermining your long-term success. The best and safest beverage choices for the carnivore diet remain plain water, sparkling water, and bone broth.
