Negative Calorie Foods
A single unit of energy is called a calorie. Energy can also be measured by a number of other methods as well. The amount of calories in food depends on its nutrient structure, while the calories contained in an item of food refers to the average amount of energy measured from a wide range of samples of that food item.
1 calorie = 4.184 joules
1 negative calorie = -4.184 joules
Calories are commonly referred to as kilocalories.
1 kilocalorie (kcal) = 4.184 kilojoules (kJ)
Foods that use more calories to digest when compared to the number of calories contained in the food are called negative calorie foods. They make the body work a lot harder to gain energy from these food items. What gives negative calorie foods a wonderful naturalistic fat-burning ability is the low availability of calories to the body as opposed to other foods that have the same calorie count. Take for example, a piece of chocolate fudge that has 400 calories but requires 150 calories to digest. This means a total of 250 calories is added to body fat. A raw piece of celery containing five calories uses a lot more calories in the process of chewing and digestion, thus taking up body fat to finish the process.
