- Tomatoes contain 32 calories per standard serving (one cup: 180 grams). They consist of 94% water and 1.5 grams of fiber.
These foods are promoted as negative-calorie because of their high water content and soluble fiber. Other examples include zucchini, berries, lemons, broccoli, grapefruit, and watermelons.
The theory about negative-calorie foods
It’s claimed that you can quickly shed off extra pounds by consuming tons of these negative-calorie foods. That’s because specific food items require more energy from your body to process them in comparison to what food itself provides for you. Theoretically, the result should be a miracle food that makes a calorie deficit after eating. One popular example of negative-calorie foods is celery because it mainly consists of fiber and water. Thus, proponents claim you will burn or lose more calories by eating this food.
The facts about negative-calorie foods
These negative-calorie claimed foods are sustenance that has fewer calories than what your body expends to digest these consumed food. However, the reality is that these ‘negative calorie’ foods still contain calories but in minimal amounts. They also have high water content and soluble fiber, making the regular consumption of these foods help you lose weight. During the whole day, up to 5% to 10% of your total energy goes to your digestive system, and it stores these nutrients coming from the food you consume.
Although there’s no scientific evidence backing that these foods are negative in calories, it’s still possible to have foods that are negative in calories. However, even if nonstarchy vegetables and celery are not negative-calorie, they are still a great addition to your diet because they still possess relatively low levels of calories.
There are no existing negative-calorie foods
Although most foods that are marketed as ‘negative calorie,’ there’s no real existing foods that are negative in calories. Because there is no scientific evidence that they need more energy or calories to consume, process, and digest than what they give your body. However, most of these foods are still nutritious and are recommended to be added to your diet.
