A single zucchini's calorie count varies primarily by its size, with a medium-sized one containing approximately 33 calories. This low-calorie density, combined with high fiber and water content, makes it a valuable addition to a healthy eating plan.
The Low-Calorie Champion: Zucchini by Size
Zucchini's mild flavor and ability to blend into many dishes make it an ideal option for adding bulk and nutrients without significant calories. Here is a breakdown of the typical calorie content based on size:
- Small zucchini (approx. 118g): Around 20 calories.
- Medium zucchini (approx. 196g): Approximately 33 calories.
- Large zucchini (approx. 323g): About 55 calories.
This low caloric load is a key reason zucchini is often used as a substitute for higher-carb foods like pasta, creating satisfying and healthier meals.
Nutritional Profile of Zucchini
Beyond its low-calorie status, zucchini is packed with essential nutrients, especially when eaten with its skin on. A single medium zucchini provides a significant portion of your daily vitamin C and potassium needs.
- Excellent source of antioxidants: Zucchini's skin is rich in antioxidants like lutein and zeaxanthin, which are crucial for eye health and protecting your body from free radical damage.
- High in water and fiber: Composed of roughly 95% water, it helps you feel full and hydrated, which can be beneficial for weight management. The fiber aids in healthy digestion and gut health.
- Rich in vitamins and minerals: It is a good source of potassium, manganese, vitamin B6, and folate, all of which are vital for proper body function.
How Zucchini Supports Weight Management
Zucchini is a staple for those focusing on weight loss due to its specific nutritional characteristics:
- Promotes satiety: The combination of high water and fiber content means zucchini fills you up without adding many calories, reducing overall calorie intake.
- Versatile, low-carb replacement: It can be spiralized into "zoodles" or thinly sliced as a substitute for pasta, dramatically cutting carbs and calories in a meal while providing a similar satisfying texture.
- Blood sugar control: The fiber helps stabilize blood sugar levels, preventing spikes and crashes that can lead to cravings and overeating.
Comparison: Zucchini vs. Other Low-Calorie Vegetables
To put zucchini's low-calorie profile into perspective, here is a comparison with other popular vegetables, based on a 100g raw serving:

Cooking Methods and Calorie Content
The way you prepare zucchini can influence its final calorie count, primarily by what you add to it. A baked or roasted zucchini tends to have slightly more calories than a raw one, mostly due to water loss and the addition of oils or dressings. For example, 100g of roasted zucchini contains approximately 23 calories, compared to 17 calories for 100g raw. The key is to be mindful of your add-ins. For maximum nutritional benefits, leave the nutrient-rich skin on.
