What drinks are allowed in keto?

5 min read

The ketogenic diet restricts carbohydrate intake to less than 50 grams per day, making every food and drink choice critical. Knowing exactly what drinks are allowed in keto is essential for maintaining this metabolic state and preventing hidden sugars from derailing your progress.

Quick Summary

A guide covering a wide range of keto-approved beverages, from hydrating staples like water to low-carb spirits. It details what to drink, which sweeteners to use, and what high-sugar beverages to avoid.

Key Points

  • Water is the #1 keto drink: Prioritize plain or sparkling water to stay hydrated and support ketosis, especially during the initial phase.

  • Choose unsweetened coffee and tea: Black coffee and unsweetened teas are zero-carb, but avoid sugary additives and creamers that can disrupt ketosis.

  • Use low-carb milk alternatives: Opt for unsweetened almond or coconut milk instead of high-carb dairy milk, and use heavy cream for added fat.

  • Stick to zero-carb spirits: Hard liquors like vodka, gin, and tequila are carb-free, but always use sugar-free mixers to prevent adding hidden carbs.

  • Avoid all sugary drinks: Regular soda, fruit juice, and sweetened coffee drinks are packed with sugar and will quickly knock you out of ketosis.

  • Replenish electrolytes: The initial water loss on keto also depletes electrolytes; replenish them with bone broth or mineral-rich water.

Keto-Friendly Beverage Staples

When following a ketogenic diet, the primary focus is minimizing carb intake. For drinks, this means prioritizing zero-carb and low-carb options. Staying hydrated is particularly crucial on keto, as the initial reduction in carbs can cause the body to excrete more water and electrolytes.

Water: Your Top Priority

Water is the cornerstone of any healthy diet, and on keto, its importance is amplified. It helps regulate body temperature, flush out toxins, and stave off dehydration, which can cause symptoms like headaches and fatigue, often called the “keto flu”.

  • Plain Water: The simplest and best option, with zero calories and zero carbs.
  • Sparkling Water: Adds a satisfying fizz without the sugar. Brands like La Croix or Bubly are excellent choices, but always check for added sweeteners.
  • Infused Water: For a flavor boost, add slices of lemon, lime, cucumber, or sprigs of mint. This adds taste without impacting your carb count.

Coffee and Tea: Caffeinated Classics

Your morning cup of coffee or tea is completely acceptable on keto, as long as you keep it unsweetened. Both black coffee and plain tea contain virtually zero carbs.

  • Coffee: Enjoy it black or with keto-friendly additions like heavy cream, unsweetened almond milk, or MCT oil for an energy-boosting "bulletproof" coffee. Avoid sugary creamers and syrups.
  • Tea: All types of unsweetened tea, including black, green, and herbal, are perfect for keto. Like coffee, flavor it with a splash of heavy cream or a keto-approved sweetener if desired.

Dairy and Dairy Alternatives

While regular dairy milk is high in carbs due to its lactose content, several excellent keto-friendly alternatives are available.

  • Heavy Cream: A high-fat, low-carb dairy option that adds richness to coffee or tea. Use it in moderation.
  • Unsweetened Nut Milks: Unsweetened almond, coconut, and macadamia nut milks are great low-carb options. Always read the label to ensure no sugar has been added, as sweetened versions are not keto.

Low-Carb Mixers and Sweeteners

For those who enjoy more flavor than plain water can offer, smart choices are key. The wrong mixer can quickly add more carbs than a meal. Similarly, choosing the right sweetener is vital.

Keto-Approved Sweeteners

  • Stevia: A natural, zero-calorie sweetener derived from a plant. It is much sweeter than sugar, so only a small amount is needed.
  • Monk Fruit: Another natural, zero-calorie sweetener that does not affect blood sugar.
  • Erythritol: A sugar alcohol that is not absorbed by the body, so it does not affect blood sugar or add carbs.
  • Allulose: A rare sugar that is not metabolized, making it a zero-calorie, zero-carb option.

Mixers for Cocktails and Other Drinks

  • Seltzer and Club Soda: Bubbly, zero-carb options for mixing.
  • Diet Tonic Water: Use this instead of regular tonic, which is loaded with sugar.
  • Sugar-Free Syrups: Brands like Skinny Mixes offer a variety of zero-carb, sugar-free syrups for flavoring coffees, teas, and cocktails.

Alcoholic Beverages on Keto

While moderation is always recommended, there are several low-carb alcohol options that can be enjoyed on a keto diet. Remember that your body prioritizes metabolizing alcohol, which pauses fat burning temporarily.

Pure Spirits

  • Zero-Carb: Vodka, gin, tequila, rum, and whiskey are all zero-carb options. Drink them straight, on the rocks, or with a keto-friendly mixer.

Wine

  • Dry Red and White Wines: These contain very little residual sugar, with around 3-4 grams of carbs per 5-ounce glass. Opt for dry varieties like Pinot Grigio, Sauvignon Blanc, or Cabernet Sauvignon.

Beer

  • Low-Carb Beer: Most regular beer is high in carbs and should be avoided. However, many light beers are low-carb, some as low as 2-5 grams per bottle. Always check the label.

Drinks to Avoid on Keto

To prevent getting kicked out of ketosis, it's vital to know which beverages are off-limits due to high sugar and carb content.

  • Regular Soda and Sugary Sports Drinks: These are packed with sugar and are a definite no-go.
  • Fruit Juice: Even 100% fruit juice is high in natural sugars and should be avoided.
  • Sweetened Teas and Coffees: Bottled iced teas, sweetened coffee drinks, and mochas from cafes are typically high in sugar.
  • Sweet Wine and Regular Beer: Avoid sweet dessert wines, wine coolers, and traditional high-carb beers.

Hydration tips for the keto diet

Hydrate Consistently: Don't wait until you're thirsty to drink water throughout the day, as a low-carb diet can increase water excretion.

Replenish Electrolytes: Because keto can deplete electrolytes like sodium, potassium, and magnesium, consider adding mineral water, bone broth, or a pinch of sea salt to your water.

Opt for Hydrating Foods: Incorporate water-rich, keto-friendly foods like cucumbers, celery, and leafy greens into your diet.

Watch Your Urine: A good indicator of proper hydration is light yellow urine. If it is dark, you may need to increase your fluid intake.

Be Mindful of Alcohol: Consume alcohol in moderation, as it can be dehydrating and affect your tolerance on a keto diet.
