A good snacking strategy is to choose low-calorie snacks, ideally between 100 and 200 calories, that offer a good balance of macro and micronutrients, says Eleana Kaidanian, a registered dietitian with her own practice.

Kaidanian says fruits and vegetables typically make for great low-calorie snack options, as they also offer plenty of vitamins, minerals, fiber, and hydration. She recommends pairing them with lean protein or healthy fats, to make your snack more filling and satisfying.

Here are some nutrition-packed, low-calorie options for the next time you're craving a snack.

1. Mango with chilli and lime

One mango contains:

• Calories: 126
• Protein: 1.72 grams
• Carbs: 31.5 grams
• Fat: 0.8 grams

A mango makes for a healthy and delicious snack, says Kaidanian. Low in calories and fat, it provides over 50% of your daily vitamin C requirement, as well as other nutrients like vitamins A and B, copper, and fiber. Try seasoning your mango with lime and chili for additional flavor. (This is a popular Mexican snack caled mango con chili y limón).

2. Watermelon with sunflower seeds

One cup of diced watermelon with one tablespoon of roasted sunflower seeds contains:

• Calories: 128.1
• Protein: 3.66 grams
• Carbs: 15.26 grams
• Fat: 7.28 grams

Watermelon is a low-calorie fruit with a high water content, making it very hydrating. Kaidanian recommends pairing it with some sunflower seeds, to add protein and healthy fats to your snack.

Sunflower seeds, like most nuts and seeds, are calorie-rich; however, they can still be a part of a low-calorie snack as long as you stick to a small portion. "Remember, portion size is key," says Kaidanian.

3. Homemade popcorn

Two cups of air-popped popcorn contains:

• Calories: 62
• Protein: 2.06 grams
• Carbs: 12.44 grams
• Fat: 0.72 grams

Popcorn is a healthy, low-calorie, low-fat snack. Because it's a whole grain, popcorn also offers fiber and several vitamins, minerals, and antioxidants. Kaidanian suggests air-popping your own, and adding seasonings like cayenne pepper, zaatar, black garlic, or nutritional yeast.

4. Apple slices with nut butter and cinnamon

One apple with one tablespoon of peanut butter contains:

• Calories: 188.6
• Protein: 3.98 grams
• Carbs: 28.94 grams
• Fat: 8.2 grams

A healthier take on nachos, apple slices paired with nut butter and a dash of cinnamon can make for a fun snack. Kaidanian recommends leaving the skin on the apple for added fiber.

Alternatively, you can pair nut butter with other fruits like bananas or berries. Ants on a log is another great combination, made with celery sticks, nut butter, and raisins.

5. Hummus with veggies

Three ounces of veggies with two ounces of hummus contains:

• Calories: 136.2
• Protein: 4.9 grams
• Carbs: 17.08 grams
• Fat: 5.16 grams

Hummus goes great with several veggies, says Kaidanian, including carrots, beets, and peppers. You can also experiment with making different types of hummus, including garlic hummus, sun-dried tomato hummus, bell pepper hummus, and black bean hummus.

6. Roasted beans

Fifty grams of roasted edamame contains:

• Calories: 200
• Protein: 21.65 grams
• Carbs: 15 grams
• Fat: 6.65 grams

If you're in the mood for something crunchy, Kaidanian recommends opting for roasted beans instead of pretzels or chips, which have little nutrition and tend to be high in calories.

Beans on the other hand are lower in calories and offer protein and fiber. She suggests trying roasted chickpeas, edamame, or fava beans.

7. Chia pudding

One hundred grams of chia pudding contains:

• Calories: 125
• Protein: 1.88 grams
• Carbs: 10 grams
• Fat: 8.12 grams

Chia pudding can be a rich and creamy snack. Kaidanian says to make your own with unsweetened almond milk. She says you can also add bananas, strawberries, cinnamon, or unsweetened cocoa powder to your pudding for extra flavor and nutrition.

8. Vegetable soup

One cup of vegetable soup contains:

• Calories: 88.9
• Protein: 4.16 grams
• Carbs: 14.5 grams
• Fat: 2.04 grams

If you're in the mood for comfort food, have some vegetable soup. Store-bought soups often have a lot of sodium, so make your own at home, if possible. Kaidanian recommends adding beans or cubed tofu to bump up the protein.

9. Kale chips

1.5 cups of baked kale chips contains:

• Calories: 112
• Protein: 3 grams
• Carbs: 10 grams
• Fat: 8 grams

Kale chips are another crunchy treat to munch on. You can make your own at home by tossing kale with some olive oil, apple cider vinegar, and sea salt, and popping it in the oven for around 20 minutes.

10. Baked sweet potato fries

One cup of baked sweet potato fries contains:

• Calories: 162
• Protein: 1.82 grams
• Carbs: 18.8 grams
• Fat: 9.19 grams

Baked sweet potato fries are a healthy alternative to fried potato chips. Sweet potatoes are rich in vitamins, fiber, and antioxidants and can contribute to better eyesight, immunity, and blood sugar management.

Insider's takeaway

If you're trying to reduce your calorie intake, you have plenty of delicious and satisfying snack options to choose from. The trick is to choose nutrition-rich snacks that offer fiber, lean protein, and healthy fats.

Opting for low-calorie snacks has several benefits, including better blood sugar and blood pressure control. "When you eat small, frequent, balanced portions your blood sugar will stay steady as opposed to spiking and crashing with large portions of food followed by hours of not eating, resulting in low blood sugar/pressure," says Kaidanian.

Low-calorie snacks can also help with weight management, if that's your goal. "Having a small snack between meals is a great way to prevent feeling extremely hungry, which can result in overeating at the next meal and is usually coupled with making poorer food choices," says Kaidanian.
