While there are really no negative calorie foods, several products have extremely low calorie content.
A low-calorie diet can help people who are overweight or obese shed pounds. A doctor may recommend healthy weight loss. A few dangers do exist, however.
Low-calorie diets are defined, as well as the number of calories in various foods and the benefits of intermittent fasting in this article. Weight loss and almost zero calorie foods will also be included in the guide. (1)
Requirements for Daily Calories
Dietary Guidelines for Americans 2015–2020 recommends a daily calorie intake based on age, gender, and physical activity level.
However, this serves as a general guide because calorie needs vary widely from person to person and are influenced by various variables such as height, weight, and weight loss objectives. (1)
Weight Loss Tips
Experts say that to shed pounds properly, and people should:
- For six months, your weight loss goal should be 1–2 pounds per week.
- Reduce their daily calorie intake by 500–1,000.
- On most days, do 30 minutes of moderate-intensity exercise.
The weight loss should be evaluated after six months, and future actions should be considered. (1)
Diets That Have Very Few Calories
Some low-calorie diets set daily caloric intake limits, such as 1,200 or 1,500 calories for women and 1,500 for men. (2)
When trying to shed pounds on a low-calorie diet, it's critical to ensure that the food you're consuming is well-balanced nutritionally. (2)
On the internet, you can get a wide variety of meal plans. A nutritionist-designed diet is preferable because it ensures that the meals are rich in essential nutrients, such as vitamins, minerals, and fiber, which are necessary for good health. (2)
Getting adequate nutrition requires consuming sufficient calories from whole, unprocessed foods. As an example, a 1,320-calorie burger dinner with fries and cola would not be enough to meet a person's daily nutrient requirements. (2)
Diets with Low Calorie Count
You're following an extremely low-calorie diet at a daily caloric intake of less than 800. Some extremely low-calorie diets call for a daily calorie intake of just 500. It is perilous for a person to embark on a calorie-restricted diet without medical supervision. (2)
Those with obesity who cannot have bariatric surgery may benefit from a highly low-calorie diet to lose weight rapidly and safely.
A doctor may prescribe a liquid form of an extremely low-calorie diet for a set period. Vitamins, minerals, electrolytes, and fatty acids will all be included in the concoction. Monitor weight loss and blood pressure and do blood tests to confirm that the patient is within healthy norms. (2)
An intermittent fasting diet entails alternating fasting times and periods of eating normally. In this method, a person alternates between days of normal eating and days in which they restrict their caloric intake by 25% or more. (3)
On certain days of the week, a person can fast for the entire day. You can eat as much as you like on five days of the week and only 400–500 calories on the other two. (3)
People who follow this method only eat within a set period, such as 8 am to 3 pm, then fast for the rest of the day, allowing them to lose weight. The 16:8 diet is one of several variations on this theme. (3)
Some studies on intermittent fasting imply that the body's adaptations to calorie restriction may limit subsequent weight reduction, but this is not universally accepted. (3)
Calorie Content of Various Food Types
The amount of calories in various foods varies according to the amount of macronutrients in those foods.
This is what the USDA has to say about it:
- carbs provide 4 calories per gram
- fat provides 9 calories per gram
- protein provides 4 calories per gram
People can find out how many calories are in different foods using an online calculator or app. Apps often allow people to input meals they regularly eat to calculate how many calories they consume daily. (4)
Several ways to improve or maintain one's health include low-carb, low-fat, and even high-fat diets. A low-fat diet is a simple and effective strategy to reduce calorie intake. (4)
There are more calories in fat per gram than in protein or carbs. Hence doctors may recommend a low-fat diet to patients. Some evidence suggests high-fat foods such as cookies, cakes, French fries, and another fatty fare may be less nutritionally dense than fruits and vegetables. (4)
There are "good fats" and "bad fats" in fat consumption. People's ability to make well-informed dietary decisions is enhanced when they know the distinctions.
Low Calorie Vegetables and Fruits
A person's ability to feel complete while simultaneously reducing the number of calories they consume daily is one-way low-calorie foods can facilitate weight loss. (4)
The consumption of nutrient-dense foods that are lower in calories can help a person reduce the overall number of calories they consume in a day, which can assist them in either losing weight or keeping it healthy. (4)
A well-balanced diet should include both high-calorie and low-calorie foods. For example, meals heavy in good fats, such as eggs, nuts, seeds, and avocados, are significantly more caloric than foods like fruits and vegetables, yet they are still nutritious. (4)
The combination of calorie-dense foods like those described above with lower-calorie foods like fruits and vegetables can make meals more fulfilling and filling. In addition, substituting some high-calorie items for low-calorie foods will encourage healthy weight loss and enhance other health aspects. (4)
Replace your donut with an apple or some sautéed veggies, and you'll save calories and gain additional nutrients, including plant components, from your food. (4)
A complete meal can be created by combining low-calorie meals with higher-calorie ones. As mentioned above, there is no zero calorie food. However, several low-calorie foods are available on the market and here are the top 20 for your consideration.

Apple slices include 62 calories and about 3 grams of dietary fiber per cup (109 grams).

However, the fact that a product has a lower overall number of calories does not necessarily imply that it is superior to meals with a more significant total number of calories. (6)
This is because other factors come into play. Your body needs an adequate amount of calories each day to function to the best of its ability and to keep you feeling as well as is humanly feasible. (6)
