Coconut water is marketed as a natural hydrator, but it's surprisingly sugary.
The problem
At around 9g net carbs per cup, a bottle can carry 18g+ of sugar — enough to disrupt ketosis.
Keto alternative
For electrolytes without the sugar, use a sugar-free keto electrolyte drink or add salt to water.
