Negative Calorie Food Is A Myth!
You must have heard about negative calorie foods if you are weight conscious. It is said that negative calorie foods are the ones that burn more calories in the process of digestion and assimilation than they themselves contain. However, this concept of negative calorie foods is more of a myth. There are foods that boost the body’s metabolism more than others and there are some foods which are low in calories but require extra calories for getting digested. However, the extra calories burned will not be sufficient to help you lose weight! Sorry for shattering your dreams but negative calorie food is a myth!
Let us have look at the background of the same.
As you all are aware that it is food that supplies calories required by you to keep your heart beating, lungs working and keep other body functions going, which includes digestion. The scene is that digestion is an ongoing process and it means that what you have for breakfast might give you the energy needed to digest your dinner. So, basically you keep burning calories all the time at varying rates based on what those calories are going to be used for. If the process of calorie burning stops, the bodily functions will also stop. Since you are burning calories even when you don’t eat, it is simply not possible to account for every single calorie or to find out calories from which food are being utilized to perform a particular body function.
So called ‘negative calorie foods’
The foods that are given the title of ‘negative calorie food’ include celery, broccoli, asparagus, cucumber, grapefruit, radish and cabbage. The same goes to spicy foods and foods that contain caffeine. Even cold water is called a negative calorie food as the body burns extra calories to warm up the digestion process.
Why negative calorie food theory is not valid?
In order to understand that the negative calorie food theory is not valid, you need to understand what a calorie is in the first place!
Definition of a calorie- a calorie is a measure of the amount of energy needed to produce heat. When we talk of food, a calorie is used to define the amount of stored energy in a food. Suppose a certain food has 50 calories, it means that the potential amount of energy stored in the food is 50 calories. Foods that are high in calories have more energy compared to low calorie foods. Water has no calories and the foods that have lots of water in them are quite low in calories. However, there is no food that has a negative energy value.
Thermic effect of food
When the body utlilizes calories to digest the food, it is referred to as the thermic effect of the food. About 5-10 percent of the calories from any food is used up in digesting that food. For instance, if a particular food, let us call it food A, has 75 calories, its thermic effect lies anywhere between 3.5-7.5 calories. That is the number of calories the body will burn to digest food A. However, those calories needn’t necessarily come from food A, they can come from foods that you ate long before biting into food A.
A lot of weight loss plans based on negative calorie foods have been marketed and an internet search will take you to several sites that list the so called negative calorie foods. The truth is that the real value of these foods is not the ‘negative calorie food’ title but their ‘low calorie food’ title. Being low in calories, such foods can be consumed guilt-free as a part of any weight loss plan.
