Continued from Carbs in Watermelon: Sugar in Watermelon.

How many calories are in watermelon? Should you drink watermelon juice?

Watermelon does not contain a lot of calories. One serving of watermelon (100 grams) contains only 30 calories, but it does contain a rather high amount of carbs and sugar.

Watermelon juice is not a health drink As for watermelon juice, I think you should stay away from it, unless you think that drinking water full of sugar is somehow good for your health. Any fruit juice – and I do not see how watermelon juice is any different – contains nothing but sugar.

Sure, if you make watermelon juice yourself, it should not contain any added sugar, but the sugar that comes from your watermelon is still sugar. To make a glass of watermelon juice, you need to a lot of watermelon. Since there is 6 grams of sugar in one serving of watermelon, you probably need at least 10 servings to make a glass of watermelon juice.

How much sugar does a glass of watermelon juice contain? A lot! Forget about calories in watermelon – assuming you need 10 servings to make one glass of juice – one glass of watermelon juice contains 60 grams of sugar. That is more sugar than in 8 fl oz. of Coca-Cola.

All of which brings me to a very uncomfortable conclusion. As insane as it sounds, if you are trying to keep your carbohydrates intake reasonable, it seems that it makes more sense to drink Coca-Cola than watermelon juice.
