#8 Lettuce
Another green vegetable that’s made up of 96 percent water is lettuce. There are all different kinds of lettuce, but what they have in common is that they are all very low in calories.
Every 100-gram serving of lettuce only provides an average of 17 calories, making it an excellent food for controlling your appetite and supporting weight loss.

Now, if you want to select the lettuce variety with the lowest caloric value, you can go for either butterhead lettuce or red leaf lettuce. Both contain only about 13 calories per 100-gram serving.
