As the temperature rises day by day, many beauty lovers have begun a weight loss plan for the new year. Among the many weight loss "artifacts" this year, a sportswear called "sweat suit" frequently brushes the screen. This kind of clothing takes "fast calorie burning" as the selling point, claiming to be able to "accelerate calorie consumption" and "enhance metabolism", which can be described as the "heart" of the "difficult household" of weight loss. Can one piece of clothing do that? The reporter launched an investigation into this.
"Improve metabolism and efficient fat burning", "black technology" or pseudoscience?
Ms. Wang lives in Taiyuan City, Shanxi Province, and her winter's "stickers" have made her "drift away" from her ideal weight. Not long ago, an advertisement in the elevator sweat clothing attracted her, after consulting the business, she learned that this "slimming black technology" has functions such as "improving metabolism" and "accelerating fat burning", which is very suitable for her work crowd with limited exercise time and eager to lose weight quickly, so she resolutely placed an order.
In full anticipation, Ms. Wang began to exercise, however, after each sweat suit, she would feel hot and stuffy, dizzy and dry, difficult to persist for a long time, and the exercise time was even shortened compared to before. Ms. Wang told reporters that now this weight loss "artifact" has been thrown into the wardrobe to "eat ash".
The reporter consulted the product to a popular single product with a monthly sales of more than 6,000 pieces of sweat clothing online store, the merchant explained, "sweat clothing using thermal control silver technology fabrics, can form a thermal cycle and heat reflection on the body surface, heat reflection can multi-fold calorie consumption to enhance the body's metabolic effect, thermal circulation effectively open the body pores to activate sweat glands, to achieve sweat and fat burning phenomenon", as for the weight loss effect, "customer feedback generally monthly weight loss of about 2-20 pounds." A sales anchor also declared, "As long as it is easy to be fat and has no time to exercise, you can wear sweat clothes to improve the efficiency and effect of exercise."
An introduction to the principle of sweat clothing on a sweat clothing online store.
However, the reporter's Online search found that many sports enthusiasts have released videos of sweating clothes experience, and the vast majority of people said that the weight loss effect of wearing sweating clothes is not obvious, and wearing them for a long time may lead to excessive dehydration, causing damage to the body, and even causing life danger.
Experts: Weight loss ≠ weight loss Sweating ≠ fat burning
The reporter learned that the principle of sweat clothing is not complicated: through the waterproof material to wrap the human body partially, and the outside world to form a certain confined space, so that the heat generated by the movement can not be quickly dissipated, in this case, the human body in order to maintain a constant body temperature needs to further increase the perspiration, so as to achieve "sweat".
Sweat suits are not new. Originally, it was designed for boxing, weightlifters, etc. who needed to lose weight, and they met the weight requirements of the competition through rapid dehydration and weight loss. After the weighing session, athletes should replenish water and electrolytes in time to prevent excessive dehydration from causing the competitive state to decline.
Cheng Jingmin, director of the Health Management and Policy Research Center of Shanxi Medical University, stressed that this way of weight loss is not weight loss, "weight loss is mainly to reduce water, and weight loss requires fat loss." In addition, the amount of sweating is not necessarily related to the fat burning effect, because 84% of the lipolysis product is carbon dioxide, which is exhaled by the lungs, "In other words, the calories consumed for 1 hour of running are fixed, and it has nothing to do with sweating." ”
Earlier, a famous diver also said bluntly on the social platform that the sweat suit "is like wrapping a layer of tin foil on the body, airtight", "after sweating, the weight is indeed light, but the weight of drinking two sips of water is back.".
A test of sweat clothing brand about increasing calorie consumption of sweat clothing.
Guo Yu, a physical fitness coach at the sports team of Guangzhou Sports Vocational and Technical College, said that the additional energy consumption obtained by wearing a sweaty suit is insignificant and not worth the loss compared with the negative effects such as the resulting feeling of stuffiness, dehydration and skin deterioration. Moreover, these discomforts may also make people unconsciously reduce the intensity and duration of exercise, but affect the effect of exercise and reduce calorie consumption.
As for the merchant's claim that the sweat suit can "enhance the resting metabolism after exercise", Guo Yu said that rest metabolism generally refers to the calories consumed by the human body to maintain basic life activities and quiet state, which is related to comprehensive factors such as exercise, rest, diet, etc., and will naturally increase in a long period of time after exercise. ”
Weight loss cannot be achieved by taking shortcuts
Respondents said that for consumers with underdeveloped sweat glands, who want to experience sweating sensation and rapid dehydration, they can try to buy sweating clothes to experience, but if they feel uncomfortable during exercise, they should stop in time, and they should replenish water and electrolytes in time after exercise to prevent excessive dehydration; and for those who expect to lose weight through sweating clothes, it is recommended to take other ways.
Professor Chen Anping, dean of the School of Physical Education of Shanxi University, said that weight loss is a "project" that needs to be adhered to for a long time, and scientific exercise, balanced diet, adequate sleep, etc., are indispensable. If you pursue temporary weight loss by taking shortcuts, you may lose more than you lose.
He suggested that if you want to lose weight through exercise, you can use aerobic exercise with strength training, and those with limited time can try a certain intensity of interval training within the range of physical tolerance. At the same time, it is recommended that you wear comfortable and breathable clothing when exercising, such as clothes with perspiration wicking, quick drying and other functions.
For weight loss people with a large weight base and hope to improve resting metabolism, Guo Yu suggests to take a multi-pronged approach, in addition to regular exercise, refusal to diet, but also pay attention to protein, water and other intake, and ensure adequate sleep.
