While there’s no such thing as a zero-calorie food, there are foods you can enjoy freely without having to worry about packing on the pounds.
According to nutritionist Dr. Lisa Young, these foods generally fall into one of two categories: non-starchy fruits or vegetables.
Young says there are few reasons why you won’t gain weight from eating these foods:
They’re mostly made up of water.
They’re low in calories.
They contain fiber, which helps make you feel and stay full.
Although these fruits and vegetables aren’t high in protein, they’re packed with plenty of vitamins, antioxidants, and other nutrients that have numerous benefits for your health.

Celery
You’re best off eating celery when it’s fresh, though. The vegetable loses many of its antioxidants within five to seven days of being purchased.
Kale
Kale is light in calories — one cup of raw kale only has about 33 calories — but it contains close to three grams of protein and 2.5 grams of fiber per serving.
It’s one of the relatively few foods that contains an omega-three fatty acid, a nutrient that most people rely on fish to get. Like other kinds of lettuce, kale is also high in vitamins and folate.
Blueberries
Blueberries’ claim to fame is their antioxidant content. The fruit has more antioxidants than any other fruit. And for all the fiber a cup of blueberries packs — 14% of your recommended daily value — it only has around 85 calories.
Cucumbers
A fruit that is mostly made up of water, cucumbers only contain 16 calories per serving. The seeds and skin contain most of the fruit’s nutritional value, so you’re best off not peeling your cucumbers.
The peel and seeds provide both fiber and a form of vitamin A known as beta-carotene, which is known to be good for your eyes.
Tomatoes
And for all the nutrients it boasts, one medium-sized tomato only has around 25 calories.
Grapefruits
Studies have shown that adding grapefruit to your diet can increase weight loss, which is often why it’s considered a diet food. This is because grapefruits are high in fiber, which keeps hunger at bay by stabilizing blood sugar levels and helping you feel fuller for longer. There are only 50 calories in one half of a grapefruit.
The vitamin C found in grapefruit can reduce the risk of a number of health problems, like cancer and heart issues. Grapefruit can also work wonders in lowering cholesterol and improving digestion, and the folate found in the fruit makes it an ideal snack for pregnant women.
Broccoli
Broccoli is most nutritious when eaten raw or when steamed. This super vegetable contains sulforaphane, an anticarcinogen that works to destroy cancer-causing chemicals that the body might take in either through the environment or through food.
Besides vitamins A, C, E, and K, one serving of steamed broccoli contains approximately 20% of your daily fiber requirement. Plus, there are only about 31 calories in one serving.
Cantaloupe
Plus, since water makes up 90% of cantaloupe, there are only 55 calories in one serving.
Cauliflower
Although its white color may make people think otherwise, cauliflower is actually a very versatile and nutritious vegetable. It contains antioxidants and phytochemicals — both of which help to fight off chronic disease — and it’s an excellent source of folate, fiber, and vitamins C and K.
There are around 25 calories in one serving.
Blackberries
Blackberries’ health benefits are incredibly versatile. Like many other berries, the fruit is rich in vitamin C as well as antioxidants known as bioflavonoids.
Beyond that, eating blackberries can aid with digestion and staying alert, and tightens tissue, leading to younger-looking skin. There are around 62 calories in a single serving of the berries.
Lettuce
Most types of lettuce — whether it’s romaine or iceberg — only have about 10 to 2o calories per serving. And although lettuce won’t add a lot of protein to your diet, it will add plenty of vitamins and nutrients like folate, iron, and vitamins A and C.
Oranges
And if you’re not eating that white stuff under an orange’s skin — pith — you should start. Pith contains a lot of fiber, which helps lower cholesterol and blood sugar levels.
Strawberries
There’s more vitamin C in one serving of strawberries than there is in one orange. In addition, strawberries are also bursting with polyphenols, a type of antioxidant.
Strawberries are also a good source of potassium and fiber, and they’re fat-free, sodium-free, and cholesterol-free, which makes them healthy for the heart. One cup of the fruit only has around 50 calories.
Honeydew melon
Honeydew melon has only slightly more calories per serving than cantaloupe (64), and the majority of these calories come from the 14 grams of natural sugar the fruit provides.
Honeydew also contains over half of the recommended daily value of vitamin C, as well as copper, which is crucial for healthy skin.
