In order to do a negative calories food list, we must be precisely clear on what we mean. There has been some confusion about the meaning of negative calories. Some have thought that this kind of food contains no calories at all. This is impossible as any type of food contains at least some energy.
The thing about negative calories is that they increase metabolism naturally and the result is weight loss, which doesn’t usually happen when eating a meal where these foods are not included.
Negative calorie food means foods which contain so little energy that the body actually uses more energy to digest and to absorb the nutrients. If you substract calories, you will burn from the calories you eat and the result will be negative. Only by digesting the food you have eaten, there will be a net loss of energy or a negative energy balance. This is what must happen if you want to lose weight but with these foods it is said that you don’t have to do anything but eat them to accomplish that. Proteins can also be eaten in combination with this food, and they are advisable if you want to use negative calories for a weight loss because they will help you control your appetite as well as increase your metabolism.
As I showed earlier this negative calories diet works on the premise that by eating some calories which are considered negative, you can lose weight. This diet is controversial because this theory is not scientifically tested, as no foods actually possess ‘negative calories’. However, advocates of the negative calories diet, state the fact that it is possible to eat and lose weight.
The theory behind the negative calorie diet is extremely appealing. It works on the idea that your body has to burn energy in order to digest certain foods. As a consequence, your body is actually burning fat. For example, an orange, which may contain 50 calories, would need a certain amount of energy from your body to process all the nutrients and vitamins within. In doing so, you would burn more than 50 calories. This is also dependent on the speed of your metabolism.
The negative calorie diet claims that after you consume certain ‘negative calories food’ your body is left with a net calorie results which is a negative calories deduction. So, for example, for every orange you eat, you should burn off 25 calories. You should choose to eat frequent healthy meals in order to increase the speed of your metabolism.
Critics of the negative calorie diet argue that no foods posses ‘negative’ calories and that you cannot lose weight only through eating. They also say that by following the negative calorie diet, you are potentially offsetting your positive calories energy reserves, canceling in this way the effectiveness of weight training.
They also add the fact that the human body needs calories in order to create energy both for exercise and for recovering from exercise. On the other side, those who think this negative calories diet is really effective, say that it may be possible that there are not such foods which contain ‘negative’ calories but they state the fact that by ingesting certain foods you are increasing the metabolic processes which can result in weight loss.
Is this really possible? Can food actually have not only calories, but negative calories? And if it is possible what effect would ingesting negative calories really have?
Could you eat your way to fat loss and the more you eat the more you lose? This may sound a little ludicrous and also impossible. But, in a twisted sort of way, there may be some truth to this innovative perspective on the composition of some foods.
All right, there is no such thing as negative calorie food. Not until these particular foods have been ingested. What happens after that may come dangerously close to what could ultimately be interpreted as truly fat loss response on the part of resulting internal metabolic processes.
All foods have a caloric nutrient ( carbohydrate, fat, protein), and vitamin and mineral (enzyme producing) content.
Enzymes are not found in foods and it has been simplified by researchers the fact that vitamins can be considered biochemicals found in foods, that stimulate living tissue to produce enzymes that are sufficient to breakdown that particular food’s caloric nutrients.
This simple definition of vitamins can also make the understanding of empty calories (junk food) easier. Foods falling into this ‘empty’ calorie category would be foods with too little enzyme producing vitamin and mineral content, while containing a surplus of calories.
The ingestion of empty calorie foods requires the body to produce its own enzymes in order to be able to convert this “empty calories” into usable energy. These enzymes should be in fact reserved for the performance of other internal, and more vital metabolic reactions.
It is true that these days it is difficult to find foods that contain a sufficient amount of vitamins and minerals, meaning purely natural foods which can alone “host” caloric nutrients. This situation can be attributed to nutrient robbing pesticide application, processing, the use of preservatives, and various commonly used poor cooking practices.
In the case of the negative calories foods, however, not only do they contain a sufficient amount of vitamins and minerals to break down the host calories, but there is also a surplus of these enzyme producing biochemicals. This simply means that once ingested, these negative calories foods provide for enzyme production in quantities sufficient to break down not only the host calories, but possibly additional calories present in digestion as well.
While there are multiple versions of this diet, they all, for the most part, tell the dieter to eat and drink food products that have a negative caloric effect, which means that the number of calories your body has to expend to chew, digest, metabolize and eliminate the food is more than it gains from the food itself. A classic example of a negative calorie food would be celery, which is made primarily of water and cellulose (fiber that your body cannot digest), and non-caloric vitamins and minerals.
Different versions of this diet allow different specific foods, but they are all generally fibrous vegetables and fruits, such as: asparagus, letuce, broccoli, green cabbage, carrots, cauliflower, apples, blueberries, cantaloupes, and cranberries.
The diets claim that you can eat “all you want” of these selected fruits and vegetables and still achieve drastic weight loss.
This diet claims that weight loss up to two pounds daily is achievable. Even if this were true, weight loss this drastic would never be recommended to anyone who is not under the strict supervision of a physician. A generally accepted rate for healthy, sustainable weight loss is considerably slower 1-1.5 pounds per week. Any success that a person would have while following the negative calorie diet would be due to drastically reduced calorie intake. It should be also worth mentioning the fact that a diet consisting only of fibrous fruits and vegetables is not healthy over an extended period of time, as it will not include enough protein or essential fats.
Fruits and vegetables are good food choices because they contain large amounts of water and fiber, along with important vitamins and minerals. The large amounts of water and fiber in these foods can make you physically full.
The case of the negative calorie diet is a good thing taken to an extreme. Fibrous fruits and vegetables are a very important part of a healthy diet, but are not a healthy diet in and of themselves. Look for more sensible alternatives that include a broad range of nutrient-dense foods from a variety of sources, in sensible quantities.
