All calories have no immediate effect on our weight.
Diets are like sand at the seaside and new ones are added every week. Who should follow? In a recent large-scale diet, various diets have been observed over a longer period of time to determine which diet is predominant in weight loss. It also turns out that weight loss is not just calories. Although all participants received the same number of calories for 20 weeks, a certain group decreased most.
An American research team from Boston Children's Hospital and Framingham State University observed and controlled overweight individuals over a period of 20 weeks while following recommended dietary plans. During this period, body weight, insulin levels, metabolic hormones and calories burned at regular intervals were measured. He showed that weight loss is more important than just calories. The study results were recently published in "BMJ" magazine.
Obesity and obesity – an increasing health problem
Overweight and obesity is a growing health problem not only in America, but also in Germany. Obesity promotes multiple heart disease, hypertension, diabetes and depression (see Obesity may cause depression). Doctors and scientists are looking for desperately effective methods to counter it. Diets are good measures to lose body weight, but for most, success is short-lived. After a few months, the weight is back, sometimes even more than before.
Which diet is best for weight loss?
Which diet is most effective for long-term weight loss? This question was answered by the American research team. The researchers compared three diets with a group of obese subjects over a period of 20 weeks. Nutrition was provided completely by the university to ensure that all participants received the same number of calories.
Three Diet – the same calorie count, different weight loss
The participants were divided into three groups. One group received a diet containing 20% carbohydrate, 40% carbohydrate in the second group and 60% carbohydrate in the third group. Although the calorie count was exactly the same in all three groups, the participants in the low-carbohydrate group showed the greatest reduction and long-term weight loss.
Calories are not equal to calories
Researchers concluded that calories from carbohydrates lead to faster fat storage. "Carbohydrates increased insulin levels during the diet and drove fat cells to store more calories," says Director of Research. med. David Ludwig, in a press release on the results of the study. Increased storage, less calories will be available for the rest of the body. Conclusion: Metabolism slows down and hunger increases, so nutritionist. Apart from this, a rapid weight gain may occur.
Weight loss in the low-carb group was significantly higher
As researchers have documented, the total energy expenditure in the low-carbohydrate diet group was the highest in 20 weeks. Participants who applied a low-carbohydrate diet with the same average body weight and caloric intake burned more than 250 kilocalories per day with more carbohydrate intake. At the beginning of the study, people with already high levels of insulin were even more severe. Here, the low-carb group burned more than 400 calories per day.
Carbohydrate insulin model
The study provides evidence that the so-called carbohydrate-insulin model is suitable for the treatment of obesity. Researchers could demonstrate that carbohydrate uptake resulted in higher insulin release. It promotes the establishment of fat stores, slows down the metabolism, prevents toughness and increases the sense of hunger. "Our observations challenge the belief that all calories are the same for the body," said Cara Ebbeling, director of the second observation. (Etc) & # 39;
