Maintaining the right hydration and beverage choices is crucial when following a ketogenic diet. While many are focused on what foods to avoid and consume, it's equally important to consider your drink options. This article explores the world of keto-friendly drinks, focusing specifically on the popular debate around Coke Zero and its place in a ketogenic lifestyle.
Keto-Friendly Drink Options
Staying hydrated is essential for anyone, but it's particularly important when following a low-carb diet to avoid the dreaded "keto flu." Here's a breakdown of suitable beverages:
- Water: Essential for hydration, regulating body temperature, and maximizing physical performance.
- Sparkling Water: A bubbly and refreshing way to hydrate with zero carbs and calories. Options like La Croix are a great choice.
- Coffee: Enjoy your morning energy boost black or with keto-friendly coffee creamers to limit carbs.
- Unsweetened Tea: A carb- and calorie-free option that's perfect hot or iced.
- Diet Soda: A permitted indulgence in moderation, as artificial sweeteners lower the carb count.
- Non-Dairy Milk: Unsweetened cashew or almond milk provides fats and protein without the carbs.
- Keto-Friendly Shakes: Many shakes minimize carbohydrate consumption while providing a quick energy boost. Atkins shakes offer ready-to-drink options in various flavors.
- Bone Broth: A tasty and nutritious drink option.
Drinks to Avoid on Keto
Certain beverages can derail your progress on a ketogenic diet due to their high carb and sugar content:
- Non-Diet Soda: Drinks like Pepsi are loaded with carbs and can hinder keto progress. One 12 oz. Pepsi has a whopping 41 grams of carbs.
- Sports/Energy Drinks: These are often packed with sugar and carbs, making them unsuitable for keto.
- Vitamin Water: Standard vitamin water is high in sugar and should be avoided. Opt for Vitamin Water Zero instead.
- Hot Chocolate: Most hot chocolate varieties are high in carbs and sugars.
- Mocha: A typical mocha contains milk, whipped cream, and mocha sauce, making it a carb-filled beverage.
- Fruit Juices: An 8 oz. cup of apple juice contains around 24 grams of carbs.
- Lemonade: Typically high in sugar.
The Diet Soda Dilemma: Coke Zero and Keto
Diet soda, including Coke Zero and Diet Coke, has long been a go-to for those seeking a sugar-free alternative to regular soda. These beverages utilize artificial sweeteners to replicate the sweet taste without the carbs and calories. However, their impact on health and ketogenic diets is a subject of debate.
What is Diet Soda?
Diet soda is a carbonated beverage where table sugar is replaced with zero-calorie sweeteners or sugar alcohols. For example, Diet Coke contains aspartame as its primary sweetener.

Ingredients in Coke Zero and Diet Coke
Both Diet Coke and Coke Zero contain carbonated water, caramel color, phosphoric acid, aspartame, potassium benzoate, citric acid, and caffeine. Coke Zero also includes potassium citrate, acesulfame potassium, and natural flavors.
The Concerns Surrounding Artificial Sweeteners
The primary concern with diet soda lies in the use of artificial sweeteners like aspartame, saccharin, and sucralose.
Aspartame: A Closer Look
Aspartame breaks down into phenylalanine, aspartic acid, and methanol upon consumption. While phenylalanine is generally recognized as safe in whole foods, it can be toxic in large doses. Methanol, another component, can convert to "free methanol" at high temperatures, which can be harmful.
Potential Health Risks
- Kidney Function: Long-term consumption of diet soda has been linked to a decrease in kidney function.
- Cardiovascular Disease: Diet soda consumption may contribute to cardiovascular issues.
- Metabolic Effects: Artificial sweeteners can disrupt metabolism by triggering a sweet taste without a corresponding increase in blood glucose and insulin levels.
- Gut Microbiome: Artificial sweeteners may negatively impact the gut microbiome, potentially leading to insulin resistance.
- Cancer Risk: Some studies have classified aspartame as a potential carcinogen based on animal studies.
Artificial Sweeteners and Sugar Cravings
Artificial sweeteners can trigger reward pathways in the brain, leading to cravings for more sweet foods. This can make it harder to stick to a ketogenic diet in the long run. When the sweet flavor comes without calories, the pathways are only partially activated, according to the Yale Journal of Biology and Medicine, which leaves your brain feeling like it's missing out on something physiologically. And when your brain isn't fully satisfied, it continually seeks more of what it wants.
Artificial Sweeteners and Weight Gain
Despite having zero calories, artificial sweeteners may contribute to weight gain by disrupting gut bacteria, reducing feelings of fullness, and prompting increased calorie consumption.

Artificial Sweeteners and Metabolic Dysregulation
Consuming diet soda can work against the mechanisms of ketosis by disrupting glucose and insulin levels, potentially increasing the risk of obesity, Type 2 diabetes, and heart disease. Diabetes Care reports that drinking diet soda works directly against the mechanisms of ketosis by disrupting both glucose and insulin. This, in turn, increases your risk of obesity, Type 2 diabetes and heart disease, according to Reviews in Endocrine and Metabolic Disorders.
Coke Zero and Ketosis: The Verdict
Technically, Coke Zero doesn't contain carbs or sugar, so it won't directly kick you out of ketosis. However, the potential negative impacts of artificial sweeteners on metabolism, cravings, and overall health make it a less-than-ideal choice.
Insulin Response
Some studies suggest that artificial sweeteners like aspartame may influence the body’s insulin response in certain individuals.
Healthy Keto Perspective
From a "Healthy Keto" perspective, Diet Coke and Coke Zero contain ingredients like caramel coloring (potentially derived from GMO corn and linked to AGEs) and aspartame, which may not align with a nutritious low-carb diet.

Staying Hydrated on Keto: Why It Matters
In the initial stages of a keto diet, your body's hydration status shifts as you deplete glycogen stores. Removing processed foods, which are traditionally high in sodium, can also affect electrolyte and fluid balance. It’s essential to drink a lot of water and replenish electrolytes.
