Zero Calorie Foods List

Eating well is a necessary component to good health, but what do you do when you are watching calories? In today’s fast-paced society, it is so easy to choose an unhealthy alternative when faced with a tough decision. 

But what if there was a way to eat healthier and still be able to feel satisfied and happy with your food? If you are searching for foods that taste great, but have zero calories, you are in luck. Here is a zero calorie foods list of the best things to eat that won’t add any guilt to your daily food intake.

What Are Zero Calorie Foods?

Let’s first talk about calories, which are simply energy units. Kilocalories, or kcals, are the calories displayed on food nutrition labels. One calorie of food contains about 4.82 joules of energy.

Calories from the meals and beverages we ingest are utilized by the body in order to perform all of the operations that support daily tasks such as respiration, digestion, protein and cell component creation, powering our cells, and heartbeat maintenance.

Calories are also required for the formation and regeneration of new cells as well as for any type of workout or exercise. The calories found in food exist in the chemical bonds among the molecules in the foods’ constituent macronutrients (proteins, carbs, and fats).

The links between these molecules dissolve as our food gets digested, releasing energy (or calories). Zero calorie foods technically have no calories that may be utilized for energy.

When people explore the idea of 0 calorie foods, there is usually some leeway in the definition, so that a zero calorie item isn’t absolutely empty of calories, but the extremely few calories found within the food have little physiological impact.

Because they contain so few calories, these types of foods may serve as zero net calorie foods because you have to eat a lot of them to have a substantial effect on your daily intake.

Healthy fat-rich foods, like eggs, have more calories than fruits and vegetables but are still very nutritious. Pairing calorie-dense foods, such as those described above, with lower calorie foods, particularly vegetables and fruits, can help make mealtime more filling and enjoyable.

Furthermore, replacing some high-calorie foods with lower-calorie foods will encourage healthy weight reduction and could enhance other aspects of health.


If you usually have eggs and a sugary treat for breakfast, substitute sweets with a fruit or some sautéed veggies to cut calories and provide more nutrients. Many low-calorie foods, fortunately, can be combined with more filling foods to form a complete meal.

Having said that, there are very few actual calorie-free foods, thus the list I compiled below all include at least a few calories every serving, but their total effect on your body and overall daily caloric intake is basically negligible.

1. Zucchini

Zucchini is a type of green summer squash. It has a subtle flavor that makes it an effective ingredient in recipes. Grating zucchini into “zoodles” as an alternative for higher carb pasta has become quite popular in recent years. Zucchini is also minimal in calories, with just 27 calories per cup.

7. Lemon Water

Drinking lemon water is a famous weight loss “hack” since water is full and can encourage weight loss on its own, and adding lemon can potentially boost fat burning, feeling full, and satisfaction.

If you are used to drinking flavored or sugar-sweetened beverages, using lemon water as an initial step to transition from calorie-dense beverages to ordinary clean water can be an effective gateway. Plus, lemons have almost no calories, so lemon water is simply a calorie-free beverage.

8. Tomatoes

A good way to make sure you’re getting enough water every day is by drinking it before meals. You’ll be more likely to eat less when you have something in your stomach, so taking a sip first will help prevent overeating later on.

Frequently Asked Questions

What Happens if I Only Eat Zero Calorie Foods?

If you’re trying to lose weight, it’s important to know what happens when you eat only low-calorie foods. When you go on a diet, your body is telling you that it needs more energy than it’s getting from this diet. This can lead to cravings for certain foods and even binge eating.

So if you’re just eating foods that are low in calories but not very nutritious, then your body will be getting less than what it needs to function properly. This means that it may experience side effects like fatigue, headaches, and sickness. Make sure you strike that balance!

What Are the Side Effects of Eating Zero Calorie Food All the Time?

If you eat zero calorie food all the time, your body will eventually run out of energy. When that happens, your body will start breaking down protein from your muscles to get energy, which isn’t healthy—and can lead to muscle loss and increased risk for other health issues like diabetes and even heart disease.

Plus, if you’re not getting enough nutrients in your diet (from fruits, vegetables, whole grains), then your body might not function as well as it should. This can lead to problems like decreased immune system function and more infections.

And finally: if you don’t get enough sleep every night (which is crucial!), then you could end up feeling tired or depressed more often than usual—or even develop a sleep disorder such as insomnia or narcolepsy where you stay awake at night and have difficulty sleeping.


These foods are the perfect accompaniment for anyone who is working toward a healthier lifestyle. Use them to your advantage, whether you’re on that years-long quest to lose weight, or just looking to add some natural indulgences into your diet.

The important thing is that they’re there when you need them. You can also substitute them in place of their higher calorie counterparts in recipes, too—the flavors will be similar, and you’ll be saving a ton of calories (and money).
