On keto, water, black coffee, and unsweetened tea are essentially free, drink them all day without touching your carb budget. Skip sugary soda, fruit juice, and most cocktails, because a single glass can blow an entire day of carbs on its own. Unsweetened milk alternatives and dry wine or spirits are fine in moderation. The rule is simple: anything with 0g net carbs is a green light, and anything sweetened with sugar is the problem. Below is a full breakdown, each drink with its net carbs, so you can build a keto day around what you actually enjoy. To sanity-check any specific drink, look it up in the keto food database or drop it into the Is My Meal Keto? checker.

Everyday keto drinks (basically free)

These have little or no sugar, so you can drink them freely. Plain still water is the obvious base, aim for plenty of it, since keto is mildly dehydrating in the first weeks.

Keto coffee and tea

Coffee and tea are naturally carb-free, the carbs come from what you add. Keep milk and sweetener low-carb and you are set.

  • Black coffee, 0g net carbs. The keto staple; add heavy cream, not sugar.
  • Unsweetened tea, 0g net carbs. Green, black, or herbal all qualify.
  • Bulletproof coffee, 0g net carbs. Blended with butter and MCT oil for a filling, high-fat start.
  • Keto latte, 2g net carbs. Espresso with unsweetened almond or coconut milk.
  • Keto matcha latte, 2g net carbs. Same idea with whisked matcha.
  • Keto hot chocolate, 3g net carbs. Cocoa, cream, and a sugar substitute.
  • Whey protein shake, 4g net carbs. A quick meal replacement; pick an unsweetened or low-carb formula.

Milk and milk alternatives

Dairy milk carries real sugar, so unsweetened plant milks are the everyday keto pick. Always choose the unsweetened version, since sweetened cartons can triple the carbs.

For comparison, regular dairy milk, 4.8g net carbs per cup and oat milk, 6.5g net carbs are noticeably higher, so use them sparingly if at all.

Alcohol on keto (in moderation)

Alcohol is optional on keto, and worth an honest note. Your body burns alcohol before anything else, so drinking pauses fat-burning until it clears. Tolerance also drops on keto, people often feel drunk faster on fewer drinks, so go slow. If you do drink, dry wines and plain spirits are the lowest-carb choices. For a deeper breakdown, see the keto alcohol guide.

Drinks to avoid

These are high enough in sugar that one serving can use up your whole day of carbs. Fruit juice is the sneakiest offender, for why whole fruit is smarter, see is fruit keto.

  • Regular soda, 11g net carbs. Pure sugar; the easiest thing to cut.
  • Orange juice, 10g net carbs. Just as sugary as soda.
  • Apple juice, 11g net carbs. No fiber to slow the sugar down.
  • Coconut water, 9g net carbs. Marketed as healthy, still high in sugar.
  • Kombucha, 8g net carbs. Varies by brand, but usually too sweet.
  • Regular beer, 13g net carbs. "Liquid bread," as the nickname goes.
  • IPA beer, 14g net carbs. Craft and hoppy styles run even higher.
  • Margarita, 34g net carbs. Sweet-and-sour mix loads it with sugar.
  • Pina colada, 32g net carbs. Fruit juice and cream of coconut.
  • Long Island iced tea, 33g net carbs. Multiple spirits plus cola.
  • Vanilla milkshake, 75g net carbs. A full day of carbs in one glass.

The takeaway: default to water, coffee, and tea, reach for unsweetened plant milks and dry drinks when you want variety, and treat sugary juice and cocktails as off the menu.

Frequently asked questions

Can you drink coffee on keto?

Yes. Black coffee has 0g net carbs and is a keto staple. The carbs come from what you add, so use heavy cream or unsweetened almond milk instead of sugar or flavored syrups. Bulletproof coffee blended with butter and MCT oil is a popular high-fat option.

What alcohol is keto-friendly?

Plain distilled spirits like vodka and whiskey have 0g net carbs, and dry wines run about 2 to 4g per glass. Mix spirits with soda water or a zero-sugar mixer, never juice or regular soda. Keep in mind alcohol pauses fat-burning and lowers your tolerance on keto, so it is optional and best in moderation.

Is diet soda keto?

Technically yes, diet soda has 0g net carbs because it is sweetened with sugar substitutes instead of sugar. It will not knock you out of ketosis. That said, not everyone tolerates the artificial sweeteners well, and some find they trigger cravings, so treat it as an occasional swap rather than a daily habit.
