21 Zero Calorie Foods to Add to Your Diet

21 Zero Calorie Foods to Add to Your Diet

Calories provide our bodies with the energy it needs to function properly to keep us alive, so the idea of eating foods that contain zero calories sounds a little bit like an oxymoron. Zero-calorie foods don’t actually contain zero calories and they do not burn more calories than other foods.

They are simply whole foods that are naturally low in calories.

The theory behind zero calorie foods is that your body will use more energy (calories) digesting them than the foods themselves actually contain through a process called thermogenesis.

This is why zero calorie foods are so beneficial for weight loss.

21 Zero Calorie Foods to Start Eating for Weight Loss

One thing you’ll notice all of these zero calorie foods have in common is that they’re whole foods.

This means they provide tons of volume and take longer to digest since they contain dietary fiber, a type of carbohydrate the body can’t digest.

As a result, you’re left feeling full longer while eating fewer calories.

That’s the power of whole foods!

So if you’re trying to consume less calories and lose weight, it’s a good idea to add these zero calorie foods to your diet.

1. Apples

You know what they say: “An apple a day keeps the doctor away.”

Apples are one of the most beloved fruits due to their delicious nature and abundance of health benefits.

They’re rich in fiber, antioxidants, polyphenols, and micronutrients to keep your body healthy.

One cup (125 grams) of sliced apple contains 65 calories (1).

2. Arugula

Unbeknownst to many, arugula is actually part of the brassicas (cruciferous) family of vegetables, known for their disease-fighting properties.

Other cruciferous vegetables include broccoli, cabbage, cauliflower, kale, brussels sprouts, collard greens, and more.

Arugula in particular is high in fiber, antioxidants, chlorophyll, and phytochemicals such as glucosinolates.

Since arugula is 90% water, one cup (20 grams) of this leafy green is only 5 calories (2).

By the time your body is done digesting this zero calorie food, you will have burned more calories than you consumed eating it.

But, your body will have used the macro and micronutrients to help keep you in tip top shape.

3. Asparagus

Did you know that asparagus grows straight out of the ground like hairs on a head?

Asparagus is a flowering vegetable from the lily family, as are garlic, leeks, and onions, and can be found in white, green, and purple varieties.

White and green asparagus actually come from the same plant. Photosynthesis turns the vegetable green but when it gets covered in dirt, photosynthesis cannot occur, resulting in white asparagus.

This vegetable is full of vital minerals and nutrients like vitamins A, C, E, K, and B6, as well as calcium, copper, fiber, iron, and folate.

Asparagus contains more folate than any other vegetable, with 17% of the recommended daily value (RDV) in one cup (134 grams) and only 27 calories (3).

4. Berries

Berries are among the healthiest foods on earth and come in many different delicious varieties.

These superfoods are loaded with antioxidants, vitamins, minerals, and fiber and have been linked to lower cholesterol, improved blood sugar and insulin levels, and healthy, glowing skin.

5. Bone Broth

Don’t let this nutritious, healing food confuse you for stock.

Bone broth is made from animal bones – usually cattle, chicken, or fish – and vegetables, herbs, and spices that have been simmered for 10-20+ hours, whereas stock is only cooked for a few hours.

The long, slow simmering process for making bone broth helps extract more gelatin, collagen, and protein (amino acids), which all have incredible healing properties.

Substituting bone broth for stock is an easy swap that will lend itself very well to your health.

You can sip on bone broth, use it in place of stock in soups and stews, add it to your rice or quinoa as it cooks, or anywhere else you think it would taste delicious.

This 8oz carton of organic bone broth is only 45 calories and has 9 grams of protein!

Brussels sprouts are like little baby cabbages that grow on stalks.

They’re rich in vitamins A, C, and K, as well as fiber, folate, and manganese.

It’s an amazing source of vitamins C and K, fiber, folate, and choline – an essential nutrient that must be obtained through diet.

One cup (89 grams) of chopped cabbage contains 22 calories, making it a great way to add volume to your meals with little added calories (10).

This zero calorie food can easily be added to your diet through salads, slaws, sauerkraut, stir fry, and even stuffed cabbage soup!

The grapefruit is a cross between a pomelo and an orange that grow in clusters similar to grapes.

They can range from acidic and bitter to sweet and sugary.

Half a grapefruit (123 grams) contains 52 calories (16).
