A healthy diet is built on a foundation of nutrient-dense, lower-calorie foods, and understanding which options fit into a controlled calorie plan is a key step toward achieving your wellness goals. While counting every single calorie isn't always necessary, knowing that you have a list of dependable, low-energy options can be empowering. At roughly 40 calories per serving, foods from fruits to vegetables offer a significant nutritional punch for minimal caloric cost, providing essential vitamins, minerals, fiber, and hydration.
Nutrient-Dense Vegetables Under 40 Calories
Vegetables are often praised for their low-calorie content and high fiber and nutrient levels. For a small amount of energy, they offer a large volume of food, which helps promote a feeling of fullness. This makes them ideal for snacking or adding bulk to meals without driving up the total calorie count.
The Power of Cruciferous Vegetables
Cruciferous vegetables are packed with vitamins, minerals, and potent antioxidants. Adding them to your diet is a flavorful way to get more nutrients for very few calories.
- Brussels Sprouts: A half-cup serving of these mini cabbage-like vegetables contains approximately 28 calories and is rich in vitamin K, vitamin C, and fiber.
- Broccoli: One cup of chopped broccoli florets contains just over 30 calories and is an excellent source of vitamin C and other antioxidants.
- Cauliflower: A one-cup serving of cooked cauliflower contains about 40 calories and is very versatile, acting as a low-carb alternative to grains in recipes like 'cauliflower rice'.
Hydrating and Crispy Choices
These vegetables are mostly water, making them incredibly low in calories and excellent for hydration. Their satisfying crunch can also help curb cravings.
- Celery: Two large stalks of celery have only 18 calories and provide fiber and vitamin K. The high water content makes it a refreshing, low-cal choice.
- Zucchini: One cup of sliced zucchini has about 20 calories. Its mild flavor makes it a fantastic base for bulkier meals without adding many calories.
- Mushrooms: With around 20-40 calories per 100 grams depending on the variety, mushrooms add a meaty texture and flavor to meals for a low calorie cost.
- Tomatoes: A medium-sized tomato contains roughly 22 calories and is a great source of lycopene, a powerful antioxidant.
Versatile and Flavorful Options
Some vegetables offer powerful flavor profiles while remaining very low in calories.

- Kale: A cup of chopped kale has just 9 calories and is loaded with vitamins A, C, and K, as well as fiber and antioxidants.
Fruity Snacks Around 40 Calories
Fruits offer natural sweetness and fiber, making them a satisfying and healthy way to curb sugar cravings. While some are higher in sugar, many fit well within a 40-calorie goal per serving.
- Grapefruit: A half grapefruit contains approximately 39 calories and is packed with vitamin C. It's a filling, juicy option for breakfast or a snack.
- Strawberries: At around 32 calories per 100g, strawberries are a sweet, nutrient-rich option. They are a great source of antioxidants and fiber.

- Papaya: A 100g serving of papaya has about 32 calories and is a good source of vitamins A and C.
Beyond Fruits and Veggies: Other Low-Calorie Options
Don't limit your low-calorie search to just produce. There are other foods and beverages that can help fill you up for minimal calories.
- Miso Broth: A bowl of miso broth clocks in at about 40 calories and is a warm, savory option.
- Air-Popped Popcorn: Three cups of air-popped popcorn (without butter) is around 100 calories, meaning a smaller portion can be well under 40 calories and provides filling fiber.
- Fat-Free Cottage Cheese: A small portion of fat-free cottage cheese can be a protein-rich snack around the 40-calorie mark, with minimal fat.
How to Incorporate 40-Calorie Snacks into Your Diet
Successfully integrating these foods into your daily routine is about planning and mindful eating. Here are some simple tips:
- Preparation is Key: Wash and chop vegetables like celery, bell peppers, and carrots ahead of time. Store them in grab-and-go containers for easy snacking throughout the week.
- Combine for Satiety: Pairing a low-calorie item with a small amount of protein or healthy fat can increase fullness. For example, have celery sticks with a very small dab of hummus.
- Use as a Base: Use low-calorie vegetables as a foundation for meals. Start with a large salad of leafy greens, tomatoes, and mushrooms before a larger meal to help manage your overall intake.
- Stay Hydrated: Many low-calorie foods have high water content, but remember to supplement with plenty of water throughout the day to maximize the feeling of fullness and support metabolism.
- Listen to Your Body: Mindful eating means paying attention to your body's hunger cues. Small, frequent snacks can prevent overeating during larger meals.
