Values for rockmelon vary by brand and how it is cooked. Check the pack. General information, not medical advice.

A light fruit

Rockmelon is mostly water, so a generous bowl is a small number of calories. The comparison table shows how it sits beside other common fruit.

Weigh the flesh, not the melon

The whole-melon row is for the flesh only. The skin and seeds are not food, so a melon of any size weighs more on the scale than it does on the plate.
