Does Cucumber Water Break A Fast?

Drinking cucumber water is generally considered safe during fasting as it contains very few calories and negligible amounts of carbohydrates, protein, and fat. Consuming cucumber water may break a water fast due to its carbohydrate content, but it can be acceptable during less strict fasting diets. cucumber and mint water in a glass (top-down view)

Can I Drink Cucumber Water While Fasting?

Whether or not cucumber water breaks a fast depends on the type of fasting regimen being followed. True fasting requires avoiding all food and drink except for plain water. However, if you’re following a fasting regimen that allows for some nutrient and calorie intake during extended periods of not eating, which is called mimicking a fast, adding a few slices of cucumber to your water may be acceptable as long as it doesn’t exceed the 1 gram rule for carbohydrates and protein. Eating more than 1/8 of a medium-sized cucumber might exceed the 1 gram rule which governs these kinds of fasts, causing an insulin response thus breaking the fast. You can learn more about eating cucumbers during a fast in my other article. If aim to stay under this rule while enjoying both flavor and health benefits, all you need is just a few slices or about 1/16 of a regular sized cucumber and perhaps throw in one slice (about 1/8) of lemon into your glass for that extra zest. a glass of cucumber water decorated with mint leaves and a slice of lemon
