Net Carbs








Is Watermelon Keto

It’s a common question among those following a ketogenic diet. The keto diet has low carbs, so people often wonder which fruits have low enough carbs to eat.

People eat less than 20 grams of net carbs daily on the keto diet. Considering this, one can look at the carbohydrate content of watermelon. A cup of chopped watermelon has about 7.15 grams of net carbs (total carbs minus fiber).

The carb count doesn’t seem as bad as fruits like apples and bananas, but it’s high for those on strict keto diets. That’s more than one-third of your total daily allowance!

That means watermelon is only sometimes okay to eat on the keto diet.
