The 10 lowest-calorie foods on earth

Identifying the lowest-calorie foods can be crucial for those aiming to manage their weight, improve their diet, or incorporate healthier options into their meals. Low-calorie foods are typically high in water content and rich in nutrients, making them an excellent choice for filling up without consuming many calories. Here’s a list of 10 of the lowest-calorie foods on earth, which are not only low in calories but also nutritious and can be easily incorporated into various diets.


Celery is low in calories and rich in water and fiber, promoting feelings of fullness and aiding in digestion. It contains phytonutrients that have anti-inflammatory and antioxidant properties, supporting overall health. Celery sticks make a crunchy snack and can be added to salads, soups, and stews or used for nutritious dips like hummus or almond butter.


Cucumbers are over 95% water, making them exceptionally hydrating and perfect for weight loss diets. They contain antioxidants, including flavonoids and tannins, which prevent the accumulation of harmful free radicals and may reduce the risk of chronic disease. Enjoy cucumbers sliced in salads, infused in water for a refreshing drink, or as a low-calorie snack with a sprinkle of salt and chili powder.


Zucchini is a nutrient-packed vegetable, offering vitamin A, manganese, and several antioxidants. It’s exceptionally versatile in low-calorie cooking, from zoodles (zucchini noodles) as a pasta substitute to baked chips or added to muffins and cakes for moisture. Zucchini boats filled with lean protein and veggies offer a satisfying, low-calorie meal.


Tomatoes are an essential dietary source of lycopene, an antioxidant linked with heart health and sun protection. They also provide vitamin B9 (folate), potassium, and vitamin E. Use tomatoes to add flavor and nutrition to salads, sandwiches, and sauces, or enjoy cherry tomatoes as a sweet, snackable treat.

Leafy Greens

Leafy greens like spinach, kale, and Swiss chard are nutrient powerhouses, packed with vitamins, minerals, and fiber while extremely low in calories. They can be used as a base for salads, blended into smoothies, sautéed as a side dish, or incorporated into dishes like omelets and quiches for a nutritional boost.


Watermelon’s high water content helps keep you hydrated and satiated. It’s a good source of citrulline, an amino acid that may improve exercise performance and cardiovascular health. Watermelon is perfect as a standalone snack, in fruit salads, or blended into refreshing smoothies and popsicles.


Broccoli is a cruciferous vegetable known for its cancer-fighting compounds, such as sulforaphane. It’s rich in dietary fiber, promoting satiety and gut health. Broccoli can be enjoyed raw with dip, steamed as a side dish, or incorporated into casseroles and stir-fries for added texture and nutrition.


Cauliflower’s versatility allows it to be used in numerous low-calorie, low-carb dishes. It can mimic rice, mashed potatoes, or even pizza crust, offering a nutritious alternative to higher-calorie ingredients. Cauliflower is also high in choline, essential for brain health and metabolism.


Strawberries are a great source of vitamin C, manganese, folate, and potassium, with powerful anti-inflammatory and antioxidant properties. They’re ideal in smoothies, salads, or as a natural dessert sweetener. Dipping strawberries in dark chocolate can create a decadent yet healthful treat.


Mushrooms are low in calories but rich in B vitamins, selenium, potassium, and copper. They provide umami flavor, making them an excellent addition to enhance the taste of meals without adding many calories. Use mushrooms instead of meat in burgers, stews, or pasta dishes to lower calorie content while maintaining richness and flavor.

Incorporating these low-calorie foods into your diet can aid in weight management and improve overall health without sacrificing flavor or satisfaction. They demonstrate the diversity in nutrient-dense, low-calorie foods supporting a healthy, balanced diet.
