There are many options for low calorie snacks that are both healthy and tasty. When choosing low calorie snacks, one of the best rules of thumb is to choose actual whole foods, not ones that are prepackaged. For example, rather than choosing a package of chips that is marked as low in calories, choose a piece of fruit, or some carrots or celery sticks. The idea is to choose a snack that will contribute to a feeling of fullness, and may also offer a benefit such as protein or fiber without the addition of a lot of unhealthy fat and sugar.
Choosing the best low calorie snacks sometimes requires some creativity and willingness to take a few extra minutes to prepare something. For instance, a mixed fruit smoothie made with low-fat milk, yogurt and ice, as well as a number of different fresh or frozen fruits, and even a little flax seed or spinach, can make a great snack or even a meal replacement. Plain vegetables such as carrots, celery, or cherry tomatoes can be made more appealing with the addition of some hummus or even low fat salad dressing, or a little bit of pepper. Salt should be used only sparingly.
Plain fruit is another one of the best low calorie snacks, and there are many ways to make it more appealing as well. Frozen grapes, for example, make a great snack and taste similar to frozen dessert treats. Bananas, apples, oranges, and cherries are also popular snack foods that are fairly easy to eat on the go. Some people also enjoy adding peanut butter to a banana or apple for a little extra boost of protein. For people who don't want to snack on fruits or vegetables, there are some other low calorie options as well.
Whole grain crackers spread with low fat flavored cream cheese, hummus, low fat cheese, or even tuna fish can make excellent low calorie snacks. Even a plain hard-boiled egg can make a good snack that is high in protein, which can help to prevent cravings for other foods. Popcorn, though lacking in much nutritional value, is a food that is very low in calories, as long as it is not coated in salt and butter. A handful of walnuts, almonds, or sunflower seeds is also a good choice; though they are somewhat higher in calories, they are very filling and rich in protein.
