The Low-Calorie Powerhouse: Unpacking 100g of Cucumber
The cucumber, a member of the gourd family, is renowned for its refreshing crispness and high water content, which is approximately 96%. This makes it one of the least calorie-dense foods you can eat, perfect for adding volume to meals without a significant calorie load. A typical 100g serving contains only 15 to 16 calories, with the exact number varying slightly based on factors such as variety and ripeness.
Detailed Nutritional Breakdown of 100g Cucumber
Beyond its minimal calories, 100g of cucumber offers several other key nutrients. The United States Department of Agriculture (USDA) provides a clear picture of its composition:
- Macronutrients:
- Carbohydrates: Approximately 3.63g
- Fiber: Around 0.5g
- Sugar: About 1.7g
- Protein: Roughly 0.65g
- Fat: Less than 0.2g

The Role of Cucumbers in Weight Management
Beyond simply being low in calories, cucumbers support weight loss in several ways. Their primary advantage is their high water and volume, which helps to increase feelings of fullness and satiety without adding significant calories. This can prevent overeating and help you maintain a calorie deficit more easily. Because they are not a significant source of protein or fiber, pairing them with other nutrient-dense foods is key for sustained fullness.
Practical Ways to Incorporate Cucumbers into Your Diet
Adding this versatile vegetable to your meals and snacks is simple and delicious:
- Salads and Wraps: Slice or chop cucumbers to add a crisp, hydrating element to any salad or sandwich wrap.
- Infused Water: Add slices of cucumber to your water bottle for a refreshing, calorie-free flavor boost that encourages increased hydration.
- Healthy Dips: Use cucumber sticks as a crunchy, low-carb alternative to crackers when pairing with dips like hummus, tzatziki, or guacamole.
- Cold Soups: Blend cucumbers with yogurt, garlic, and dill to create a refreshing cold soup, like gazpacho.
- Snack Plates: Serve cucumber slices alongside other vegetables and a protein source like cottage cheese for a balanced, satisfying snack.
- As a Garnish: Use thin slices to add a touch of freshness to dishes and cocktails.
Other Impressive Health Benefits
Cucumbers offer more than just weight management support. Their nutritional profile contributes to overall wellness in several key areas:
- Hydration: Their high water content is highly effective for keeping the body hydrated, especially in warm weather or after exercise.
- Antioxidant Power: Cucumbers contain antioxidants, including flavonoids and lignans, which help protect cells from damage caused by free radicals.
- Blood Sugar Management: Early studies suggest compounds in cucumbers may help regulate insulin and blood sugar, making them a useful food for those with or at risk of diabetes.
- Heart Health: The potassium content helps balance sodium levels in the body, which is important for maintaining healthy blood pressure.
- Digestive Regularity: The fiber in cucumbers, particularly in the peel, helps promote healthy digestion and prevent constipation.
