Low fat and low fat – not just calories


All calories immediately affect our weight

Diets are like sand along the sea, and new ones every week. Who should follow? In a recent large-scale food study, a variety of diets were observed over a prolonged period to determine which diet is to lose weight. It also turned out that weight loss is not just calories. Although all participants received the same number of calories for more than 20 weeks, one group fell the most.

An American research group from Boston and Framingham State University observed and controlled overweight over a period of 20 weeks, following the prescribed diet plans. During this period, body weight, insulin levels, metabolic hormones and calories were measured at regular intervals. It has been shown that weight loss is more important than the number of calories. The results of the study were recently published in the BMJ magazine.

Obesity and obesity – an increasing health problem

Overweight and obesity are an increasing health issue, not only in America, but also in Germany. Obesity promotes a number of heart diseases, hypertension, diabetes, and depression (see: obesity can cause depression). Doctors and scientists desperately seek effective methods to prevent this. Diets are good measures to lose weight, 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? This question was answered by the American research group. The researchers compared three diets with a group of obese subjects over a period of 20 weeks. Food was 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

The participants were divided into three groups. One group received a diet consisting of 20% of carbohydrates, 40% of carbohydrates in the second group and 60% of carbohydrates in the third group. Although the amount of calories was exactly the same in all three groups, participants from the low carbohydrate group showed the greatest reduced and sustained weight loss.

Calories are not the same calories

Researchers have found that calories from carbohydrates lead to faster fat storage. "Carbohydrates have increased insulin levels during the food process and have taken fat cells to store more calories," said the research director. med. David Ludwig in a press release on the results of the study. Increased storage would be available to the rest of the body with less calories. Result: Metabolism slows down and hunger increases, so it's a nutrition expert. This condition can result in a rapid increase in body weight.

Weight loss in a low-carbon group was significantly higher

According to researchers, total energy expenditure in a low carbohydrate group was the highest in 20 weeks. With the same average body weight and caloric intake, participants who followed a low-carbohydrate diet were about 250 calories per day greater than those with higher carbohydrate intake. People who already had high levels of insulin at the beginning of the study were even more drastic. A low carbohydrate group consumed more than 400 calories per day.

Insulin carbohydrate model

The study demonstrates that the so-called carbohydrate-insulin model is suitable for the treatment of obesity. Researchers may have shown that carbohydrate intake leads to a greater release of insulin. This stimulates the formation of fat stores, slows down the metabolism, inhibits satiety and stimulates the feeling of hunger. "Our findings challenge the belief that all calories are the same for the body," says another study by Care Ebbeling director. (Vb)
