Diet myths Sports alone can not reduce excess weight
Anyone who moves regularly does not only do something good for his health, but also decreases it. Unfortunately, this seems to be just a myth, because scientists came to the conclusion that sport has only a minimal effect on whether a person is overweight or not. More important is the diet.
Bad diet is the cause of obesity
People who want to lose weight are generally advised to exercise a lot and exercise regularly. Then you could also "small sins" such as sweets or chips in front of the TV permit. However, according to researchers, lack of exercise is not the reason for overweight, but especially wrong diet. This claim, at least three doctors who clear up in a post in the journal "British Journal of Sports Medicine" with the basic myth.
Amount of movement has barely changed
"You can not run away from a bad diet," British cardiologist Aseem Malhotra declared loudly "t-online.de". Together with his colleagues Timothy Noakes and Stephen Phinney, he wrote the widely acclaimed commentary. Although sport has many positive aspects, "physical activity does not promote weight loss." The physicians explained that in the past 30 years the amount of exercise in the Western world has changed only insignificantly, but over the same period obesity has increased rapidly.
Scientists attack food industry
Rather, the type and amount of calories we eat is due to many increasing. "A poor diet causes more illness than lack of exercise, alcohol and smoking together," the authors said. The scientists are sharply attacking the food industry in their contribution. For example, companies such as Coca Cola linked their drinks and sports and conveyed the message, "It's okay to drink the products while you're doing sports." This is wrong. "An obese person does not need a bit of exercise to lose weight, you just have to eat less," Aseem Malhotra said in a BBC report. "My biggest problem is the message that you can eat whatever you want while you're exercising. That's unscientific and wrong. "
Governments called to act
In particular, the calories from sugar are seen as problematic by the scientists. According to this, the risk of becoming ill with type 2 diabetes increases ninefold if daily 150 kilocalories were consumed in the form of sugar. This is not the case with the same amount of calories from fat or protein. The physicians are calling on responsible politicians to do more to prevent the rise in obesity and, for example, ban the advertising of soft drinks and junk foods. In some countries, governments have already become active in recent years. Since 2012, there has been a "cola tax" for sugar fortified drinks in France. And in Latvia, unhealthy foods and drinks are prohibited in schools and kindergartens.
Many people do not move enough
Poor nutrition is not without its effects on people of normal weight: "Up to 40 percent of those with a normal BMI will develop metabolic abnormalities that are actually the result of being overweight," the article says. According to the authors, these include hypertension and fatty liver. Although the theory of the three doctors is controversial, almost all critics agree that most people do not exercise enough. The role of physical activity should not be completely ignored, warned Professor Mark Baker, of the National Institute of Health and Care Excellence..
Extra pounds through sports
According to various studies, "regular exercise can help to reduce the risk of cardiovascular diseases such as hypertension or heart attack." In addition, regular exercise would reduce the risk of type 2 diabetes, Alzheimer's and some types of cancer. Malhotra and colleagues also said that sport is healthy. They said fitness studios and sports organizers would have to lead by example and banish sugary drinks from their range. The fact that sport does not necessarily lead to weight loss but rather to weight gain has been shown by US scientists last year in a study. The Arizona State University researchers in Phoenix found that more body fat through sport for more kilos on the scales. (Ad)
