Is watermelon healthy?

Noom has a classification system that groups foods according to their caloric density. This refers to a measure of how much energy (calories) can be found within a given weight or volume of a food.

Green foods have the lowest caloric density and/or the highest concentration of healthy nutrients.  Think: veggies and whole grains.

Yellow foods have a mid-level caloric density and/or a medium amount of healthy nutrients. Think: lean meats and starches.

Red foods have the highest caloric density, are the most calorie-dense and/or have the least healthy nutrients. Think: red meats and desserts.

Red doesn’t mean “bad” and green doesn’t mean “good” (though it does mean “better”). We only recommend balancing things out in terms of portions and frequency.

What color are watermelons?

Within the Noom Weight program, watermelons are considered a green food.
