This is a level 1 recipe (may help support fat loss). The exact calorie count of this recipe will depend on the size you dice the watermelon and the size of your pop molds. I was able to make 10 pops, so they ended up at 25 calories each. That means you could have four popsicles for a 100-calorie snack if you wanted. (Wow!)Watermelon is not a low-carb fruit, but like other melons, it is relatively low in calories and high in fluid volume. Unless your strategy is low-carb, I would consider watermelon to be a good dietary choice if you are looking for fat loss. Melons and berries were my top picks for fruit when I was on my weight loss journey.
