Can "negative calorie food" really help you lose weight?
We all know that heat is a commonly used unit of energy, which is usually used to express the calorie content in food. The so-called "negative calorie food" means that some foods contain less calories than the energy needed for digestion and absorption. It is incorrect that eating these foods will reduce calories on the body. However, the representatives of negative calorie foods are celery and grapefruit.

Can "negative calorie food" really help you lose weight? ? Can eehealth negative calorie food really lose weight? Most of the "negative calorie foods" are high in water and fiber, which are difficult to be digested and absorbed by the human body, making the calorie consumption greater than the intake. But most of them are mainly fruits and vegetables. However, experts say that this seemingly reasonable energy subtraction is unrealistic, because even low-calorie foods, such as celery, contain more calories than the human body consumes to decompose and absorb it, because our metabolic rate will rise after eating, resulting in the thermal effect of eating, the digestion and absorption of food and the peristalsis of the stomach, which all need to consume human energy. But in fact, the thermal effect consumes very little energy, accounting for only 10% of our intake. The whole set of work includes chewing food, making food pass through the digestive system smoothly, absorbing nutrients in food and storing excess energy. Celery, grapefruit, tomatoes and cucumbers are all touted as "negative calorie foods", but there is no scientific evidence to support this view. Although their calories are really low, they consume less energy than this figure.

Does celery represent negative calorie food? Medicalnewstoday uses it instead of high-energy food. In fact, without the aura of "negative calorie food", these foods are still very valuable to people who want to lose weight because of their low calories. What we need to do is not to fantasize that eating them will make us thinner and thinner, but to replace some foods in our diet with them. For example, replacing a portion of French fries with mixed cucumber can greatly reduce our calorie intake. They not only have no burden, but also bring us various nutrients such as vitamins, minerals and plant fibers, which are also very beneficial to our health. But it should be noted that the focus of eating these foods is to "replace" calories, not "increase" calories. In other words, we should use them to replace the high-calorie foods on our plates, instead of eating high-calorie foods and then serving fruits and vegetables. If we simply add some healthy food, the total calories we consume will actually increase. A Big Mac burger with a salad will definitely contain more calories than just eating a Big Mac burger. What we have to do is "exchange" at least half a hamburger with a salad.

If you want to lose weight, the only effective formula is that you consume more energy than you eat and drink. Although the truth is clear, it is not easy to do. According to research, people tend to underestimate the calories they consume in food, and the fatter they are, the more likely they are to fall into this trap. When people enter a seemingly healthy fast food chain, they tend to underestimate the calories they ordered and order the same food. People will pay more attention when they eat in restaurants that are not so healthy in their subjective consciousness. Many studies show that the short-term benefits of diet are helpful to lose weight, but over time, more than 80% people will gain weight, especially now that high-sugar and high-calorie foods are everywhere, easy to obtain, and the temptation of advertisements and friends is increasing, which makes it difficult for people to resist the temptation of high-sugar and high-fat foods for a long time. The only way to save the weight-losing army is to change their diet and beverage choices on this basis. In the long run, this is definitely better than.

A low-calorie diet helps weight loss researchers track 2,000 overweight adults from Europe, Australia and New Zealand. These participants all suffer from "pre-diabetes", that is, their blood sugar is higher than the normal level but does not meet the diagnostic criteria of diabetes, and they have a high risk of developing type 2 diabetes. For eight weeks, these participants have been adhering to a low-calorie diet, mainly liquid, with a total calorie of about 800 calories, including soup, milkshake and hot cereal. At the same time, they also consume about 375 grams of low-calorie vegetables every day, such as tomatoes, cucumbers and lettuce. The results showed that after 8 weeks of low-calorie diet, 35% of men and women's blood sugar levels returned to normal, no longer belonging to pre-diabetes. In addition, the researchers also found that the average weight loss of male participants was 1 1.8 kg, and that of women was 10.2 kg. Compared with women, men not only lose more weight, but also have a greater decline in metabolic syndrome score, diabetes index, body fat content and heart rate.

In addition, low-calorie diet also affects women, but these changes are somewhat different from those of men. Compared with men, the level of high-density lipoprotein cholesterol in women is greatly reduced, that is, the so-called "good cholesterol" is reduced, which may be harmful to their heart health. More importantly, the bone density of female participants is also greatly reduced, which means that their bones may become more fragile, and low weight after fat removal means less muscle. Of course, it also has a good effect. I want to reduce the hip circumference of women as much as possible.

Schematic diagram of low-calorie meal? The metabolic rate of women is different every day. The gender differences in weight loss and health improvement observed in this study have physiological significance. Because of the different body composition, men have more muscles and higher metabolic rate. All participants followed a diet of about 800 calories per day during the experiment, but men usually consume more calories in their daily diet than women, so they will have more obvious calorie deficiency in the study, and the researchers also expect their weight loss to be faster than women. The significance of this study is that it shows that men usually have more weight in the abdomen than women and men, that is, visceral fat. When people reduce visceral fat, they will increase their metabolic rate and help burn more calories. Different from men, women usually have more subcutaneous fat, which accumulates in thighs, buttocks and other parts and is very important for fertility. Losing subcutaneous fat does not improve people's metabolism, because this type of fat metabolism is not active.
