Are Traditional Tapioca Pearls High in Carbs?
Yes, a half cup of tapioca pearls contains 67.5 grams of carbs. There is less than 1 gram of fiber in half a cup of tapioca pearls, making them unsuitable for the keto diet. The ketogenic lifestyle generally limits carb intake to less than 50 grams daily.

Keto-friendly tapioca pearls are made from gelatin, tea, and oil. A half cup of keto tapioca pearls made this way contains under 0 grams of net carbs. Essentially, gelatin is combined with hot water and left to set. The gelatin is then sucked into a dropper, and tiny gelatin boba pearls are dropped into very cold oil, creating ketogenic boba.
Which Milk Tea Dairy Options Are High in Carbs?
Dairy milk and some non-dairy milk are high in carbs.
Type of milk | Net carbs per 1/2 cup |
Goat | 5.5 g |
2% | 6 g |
Whole | 6 g |
Oat | 8 g |
Rice | 10.5 g |
Sweetened condensed | 83 g |
Keto-friendly milk options include heavy cream, half and half, almond milk, cashew milk, soy milk, and flax milk. Some coconut milk has five net carbs per cup, which is 1/5 of the daily carb total for the keto diet. Be sure to check the nutritional information of the coconut milk before adding it to your bubble tea.
4 Ways to Lessen the Sugar Content in Bubble Tea
Bubble tea is typically high in sugar. Here are a few ways to lower the sugar content in your bubble tea or make it sugar-free!
- Order sugar-free bubble tea, or ask for 25% sweetness.
- Request (or use) a keto sugar substitute, like stevia, erythritol, or monk fruit.
- Skip the boba pearls, ask for sugar-free jellies instead.
- Choose sugar-free toppings, like sugar-free whipped cream made from heavy cream.
Does Keto-Friendly Boba Taste as Good as Regular Boba Tea?
Keto bubble tea still tastes like sweetened boba milk tea. The most significant change would be in the low-carb, sugar-free boba pearls. Instead of tasting chewy and starchy, they’ll taste like sweetened gelatin.
Keto sweeteners taste slightly different than regular sugar. If you’re not used to them, you may notice the difference. However, keto boba tea still tastes sweet and delicious.
