When it comes to weight loss, vegetables are your best allies. Packed with fiber, water, and essential nutrients, low-calorie vegetables let you eat a lot without many calories, a strategy often called “volume eating.”
Whether you’re prepping meals or need a quick snack to survive a calorie deficit, this guide will walk you through the best veggies to support your weight loss goals.
Why Low-Calorie Vegetables Are Effective for Weight Loss
Low-calorie vegetables are rich in fiber and water, two components that increase satiety without boosting calorie intake.
They help you feel full, reduce overall food consumption, and are packed with micronutrients critical for metabolic health.
If you are trying to lose weight and cutting calories, you will definitely be hungrier than if you are eating at maintenance. And snacking on something low-calorie is definitely going to make it easier to stick to it than torturing yourself between meals.
7 Best Low-Calorie Vegetables for Weight Loss
We’ve compiled the ultimate list of the 7 best low-calorie vegetables you can eat in volume. Get ready to transform your plate and your appetite.
Cucumber
Calories: 16 per 100g
Light, crunchy, and composed of over 95% water, the cucumber is a top-tier vegetable for weight loss. It’s the perfect base for salads or a refreshing, hydrating snack straight from the fridge.
Why it works
Its high water content provides volume and helps keep you hydrated, which is often mistaken for hunger.
How to eat it in volume
Simple Snack
When I’m hungry, I eat ungodly amounts of cucumbers. Just unpeeled cucumbers. Grab one and start biting. It’s surprisingly filling.
Flavorful Side
Sliced cucumber with gochugaru, soy sauce, and rice vinegar. It’s best if you also add some sesame oil and sesame seeds, but these have more calories, can be skipped.
Tomatoes
Calories: 18 per 100g
Bright, juicy, and bursting with flavor, tomatoes are far more than just a salad ingredient. They offer a sweet and tangy taste for very few calories and are packed with antioxidants like lycopene, which is great for heart health.
Why it works
The juiciness and fiber contribute to satiety, making you feel full.

Create a massive salad
For me, the best snack is a salad. Favourite at the moment is cucumber, capsicum, and tomatoes, with a balsamic vinaigrette.
Bell Peppers (Capsicum)
Calories: 20 per 100g
Sweet, colorful, and incredibly versatile, bell peppers are a weight-loss dream. Whether you enjoy them raw, roasted, or sautéed, they add a satisfying crunch and a dose of Vitamin C to any meal.
Why it works
Their hollow structure means you can eat a lot for very few calories, adding bulk to stir-fries, fajitas, and salads.
How to eat it in volume
- Slice them into strips for a dipping snack with hummus or Greek yogurt dip.
- Chop and add to omelets, skewers, or as a topping for tacos.
Carrots
Calories: 35 per 100g
Naturally sweet and satisfying with a delightful crunch, carrots are a classic choice for a reason. They are slightly higher in calories than others on this list, but are still incredibly low-calorie and packed with beta-carotene (Vitamin A).
Why it works
The act of chewing crunchy vegetables like carrots can be more satisfying and slow down your eating.
How to eat it in volume
Shredded Snack
Carrots – I just shred them and snack on them.
With a Low-Cal Dip
Carrot (or celery) sticks with PB2 will be pretty low cal and have a bit of protein.”
Daikon Radish
Calories: 18 per 100g
If you haven’t tried daikon, you’re missing out! This large, white radish is crunchy, mild, and less peppery than its red cousins. It’s exceptionally low in carbs and high in flavor, making it a fantastic potato substitute.
Why it works
Its mild flavor absorbs other seasonings beautifully, and its texture provides a satisfying crunch.
How to eat it in volume
- Daikon – same, even better with some pickling. Quick-pickle it with vinegar, salt, and a sweetener for a tangy side.
- Cube and roast it, or slice it into “fries” for a low-calorie side dish.
Napa Cabbage
Calories: 12 per 100g
With one of the lowest calorie counts on this list, Napa cabbage is a volume eater’s best friend. Its mild, slightly sweet flavor and delicate crunch make it perfect for slaws, stir-fries, and wraps.
Why it works
You can use entire cups (or more!) to create the base of a meal for negligible calories.
How to eat it in volume
- Nappa cabbage – I usually just soak it in salty water, love the taste. This simple preparation highlights its natural flavor.
- Use large leaves as low-carb wraps for tacos or sandwich fillings.
Sauerkraut (Fermented Cabbage)
Calories: 19 per 100g
While technically processed, traditional sauerkraut (just cabbage and salt) remains a fantastic low-calorie food.
The fermentation process creates probiotics, which are essential for a healthy gut microbiome, something increasingly linked to healthy metabolism and weight management.
Why it works
It adds a huge flavor punch for very few calories and supports digestive health.
How to eat it in volume
Ensure you buy refrigerated, unpasteurized sauerkraut to get the probiotic benefits.
Sauerkraut – just use it for meals in cooking. Add a generous scoop to salads, grain bowls, or alongside a lean protein source.
Non-Starchy Vegetables vs. Starchy Vegetables
Non-starchy vegetables like spinach, lettuce, and zucchini are much lower in calories than starchy ones like potatoes, corn, or peas. While all veggies are good, if you’re in a calorie deficit, the lower the calorie density, the better.
Here’s a quick breakdown:
| Type | Examples | Calories per 100g |
|---|---|---|
| Non-Starchy Veggies | Cucumber, zucchini, spinach, celery | 10–25 kcal |
| Starchy Veggies | Potatoes, peas, corn | 70–100 kcal |
Creative Low-Calorie Veggie Snacks
Sometimes the hardest part of a diet is the between-meal hunger. Here are some tasty, filling options using low-calorie vegetables:
- Cucumber salad with vinegar, soy sauce, and gochugaru
- Carrot or celery sticks with PB2 (powdered peanut butter)
- Chopped cabbage soaked in salty water
- Sliced tomato and bell pepper with light vinaigrette
These snacks help reduce hunger pangs without derailing your calorie targets.
Zero-Calorie Vegetable Myth: What’s the Deal?
You may hear about “zero-calorie” foods. While no vegetable is truly zero-calorie, some, like celery or cucumber, are so low in energy and high in water that your body may burn nearly as many calories digesting them as they contain.
Still, this effect is minimal. It’s better to focus on filling, fiber-rich veggies than chase the zero-calorie myth.
