There is much debate over the existence of negative calorie foods. Most scientists agree that they are not real, however, so oranges would not be negative calorie foods.
As far as calories go, yes. However, as far as nutrients go, maybe not. In a nutshell, you will benefit more in the long run if you get most of your calories from carbohydrates. 45-65% of your daily calories should be coming from carbohydrates. You will want to select foods that have a high amount of nutrients per calorie. They are called "nutrient dense foods." Fat is high calorie (9 Calories per gram of fat), which means it will be harder to get as much nutrients with with a 100 Calorie spot of fatty food than it will be if you eat 100 Calories of carbohydrates.

I believe in most cases, the "negative calorie" effect works with raw, or slightly cooked, vegetables.
There are several foods that contain a large amount of nutrients. The whole egg is one of the most common foods that contain the largest amounts of nutrients
Anything that has it listed as an ingredient...most diet sodas and other low-calorie diet foods.
Low calorie diets or "fast diets" should not be the main concern. It should be whether or not you are receiving all the nutrients you need. Do not think to much on charting your calories. Simply eat green vegetables and whole grains. Other wise, low calorie foods can be found on www.low-caloriediet.com/food.
Leafy green vegetables are the best low-calorie food. Mustard, turnip, or collard creens; kale; or watercress are the most nutrient-dense foods and very low in calories.
Nutrient density
Fats (lipids) offer the most concentrated energy source (i.e the most kilojoules of energy per gram, compared with other nutrients).
The most calorie-dense element in food is fat. It provides 9 calories per gram, which is more than double the calories provided by carbohydrates and protein. Consuming foods high in fat can contribute to weight gain if not consumed in moderation.
The most basic foods essential for a healthy diet include fruits, vegetables, whole grains, lean proteins, and healthy fats. These foods provide essential nutrients like vitamins, minerals, and antioxidants that support overall health and well-being. It is important to include a variety of these foods in your diet to ensure you are getting all the necessary nutrients for optimal health.
