The idea of foods with negative calories is one of the most well-liked food trends that have recently captured everyone's interest. This notion claims that eating as many of these items as you like would prevent you from gaining weight because doing so burns more calories during digestion than the food itself, negating the calorie addition. Your body burns more calories than you ingest. This does not imply that these negative calorie foods do not contain calories.
But does this theory work? Do negative-calorie foods exist? Let's unwind to see what it means.
What Does Negative Calorie Food Mean?
The “negative calorie” food hypothesis is that the body expends energy when processing and digesting meals. According to the notion, some foods make you burn off more calories than they do. Thus, negative calorie foods need more energy for digestion than they provide the body with in terms of energy.
Celery, cabbage, garlic, and leafy greens are examples of foods with negative calories; all of these items contain very few calories, to begin with. These foods often have a low glycemic index and high fiber content.
How Does Negative Calorie Food Work?
Everything we eat contains calories, which are a crucial element of food. Calories are divided into two groups: negative and empty calories. Empty calories are those that, when consumed, such as fast food and refined sugar, provide a huge number of calories. These don't provide any nutrients.
The negative calories come from nutrient-dense, low-calorie foods. These foods supply your body with less energy than they take to digest and process. Negative-calorie fruits and vegetables are frequently marketed as having high water content and minimal calories.
You may incorporate these negative calorie foods in your diet to lose weight because your body needs a certain number of calories to maintain and produce energy.

Summing Up
Even with foods with negative calories, the energy required to chew, digest, and assimilate food is likely only a small portion of the food's calories. Despite not having negative calories, a lot of fruits and vegetables are packed with low calories and high nutrients. Numerous low-calorie protein sources are also rich in additional nutrients.
The best approach is to eat various nutrient-dense whole meals and add antioxidants in your diet that can support your overall health, including those that support healthy body weight, rather than focusing on a small list of purportedly low-calorie foods.
