Low carbide content and low fat content – not just the number of calories

Not all calories have an immediate impact on our weight

Diets are like sand at the sea and new ones are added every week. Who should watch? In a recent large-scale nutrition study, diets have been observed over a longer period of time to find out what diet has weight loss before. It also turned out that weight loss is not just about calories. Although all participants received the same number of calories in 20 weeks, one particular group declined the most.

An American research team from the Boston Children's Hospital and Framingham State University observed and controlled overweight for 20 weeks while adhering to prescribed dietary plans. During this period, body weight, insulin levels, metabolic hormones and burned calories were measured at regular intervals. It turned out that weight loss is more important than just the number of calories. The results of the study were recently published in The BMJ.

Obesity and obesity – a growing health problem

Overweight and obesity are a growing health problem not only in America but also in Germany. Obesity supports a number of heart diseases, hypertension, diabetes and depression (see: Obesity can cause depression). Doctors and scientists are desperately looking for effective ways to prevent it. Diet is a good measure of weight loss, but for many, success is short-lived. A few months later the weight returned, sometimes even more than before.

Which diet is best for weight loss?

Which diet is most effective for long-term weight loss? The American research team answered the question. Researchers compared three diets with a group of obese subjects for 20 weeks. Nutrition has been fully provided by the University to ensure that all participants receive the same number of calories.

Three diets – the same number of calories, different weight loss

Participants were divided into three groups. One group received a diet consisting of 20% carbohydrates, 40% carbohydrate in the second group and 60% carbohydrate in the third group. Although the number of calories was exactly the same in all three groups, participants in the low carbohydrate group showed the most decline and permanent weight loss.

Calories are not the same as calories

Scientists have concluded that calories from carbohydrates lead to faster fat storage. "Carbohydrates increase insulin levels during the diet and lead fat cells to store more calories," says the research director. copper. David Ludwig in a press release on the results of the study. Increased storage would be available for the rest of the body with fewer calories. The result: metabolism slows down and hunger increases, so a nutritionist. This can result in rapid weight gain.

Weight loss in the low carbohydrate group was significantly higher

As researchers show, total energy expenditure in the low carbohydrate diet group was highest in 20 weeks. At the same average body weight and calorie intake, participants who followed a low carb diet were burned approximately 250 kilocalories a day higher than those with higher carbohydrate intake. People who had high insulin at the start of the study were even more drastic. Here, the low-carbohydrate group burned an incredible 400 calories a day more.

Carbohydrate Insulin Model

The study provides evidence that the so-called carbohydrate-insulin model is suitable for the treatment of obesity. Scientists have shown that carbohydrate intake leads to higher release of insulin. This promotes the build-up of fat stores, slows down metabolism, prevents satiety and promotes a sense of hunger. "Our observations question the belief that all calories are the same for the body," says Cara Ebbeling, second study director. (Vb)
