Low carbohydrates for low fat – not just calories, it matters


Not all calories have an immediate effect on our weight

Diet is like the sea sand, and new ones are added every week. Who should follow? In a recent large-scale nutritional study, different diets have been observed over a longer period of time to identify what diet is advancing in terms of weight loss. It has also been shown that weight loss is not just about calories. Although all participants received the same number of calories over 20 weeks, a particular group declined the most.

An American research team at Boston Children's Hospital and Framingham State University observed and controlled overweight people over a 20-week period while following prescribed diet plans. During this time, body weight, insulin levels, metabolic hormones and calories burned were measured at regular intervals. He has shown that weight loss is more important than the number of calories. The results of the study were recently published in the journal "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 promotes many heart disease, hypertension, diabetes and depression (see: Obesity can cause depression). Physicians and scientists are desperately looking for effective methods to counteract this. Diets are good measures to lose body weight, but for many, success is short-lived. A few months later, weight returns, sometimes even more than before.

What diet is best for weight loss?

What 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 within 20 weeks. Nutrition has been fully provided by the university to ensure that all participants receive the same number of calories.

Three diets – Number of calories, different weight loss

Participants were divided into three groups. One group received a diet consisting of 20% carbohydrates, 40% carbohydrates in the second group and 60% carbohydrates in the third group. Although the calorie count was exactly the same in all three groups, participants in the low carbohydrate group showed the largest drop and sustained weight loss.

Calories are not equal to calories

The researchers concluded that calories from carbohydrates lead to faster fat storage. "Carbohydrates have increased insulin levels while eating and have taken fat cells to store more calories," says the research director. med. David Ludwig in a press release on the results of the study. The increased deposit would be available to the rest of the body less calories. The result: metabolism slows down and increases hunger, so the nutritionist. From this condition, a quick weight gain may occur.

Weight loss in the low-carbon group was significantly higher

As researchers have documented, total energy expenditure in the low-carbohydrate diet group was highest in the 20 weeks. With the same average body weight and caloric intake, participants who followed a low-carbohydrate diet burned about 250 kilocalories a day more than those with a higher intake of carbohydrates. People who already had high levels of insulin at the start of the study were even more drastic. Here, the low-carb group burned 400 extra calories a day.

The model of insulin carbohydrate

The study provides evidence that the so-called insulin carbohydrate model is suitable for the treatment of obesity. Researchers have been able to demonstrate that carbohydrate intake leads to a higher release of insulin. It promotes accumulation of fat deposits, slows metabolism, inhibits satiety and promotes hunger. Our observations make the belief that all the calories are the same for the body, synthesizes the second study director Cara Ebbeling. (Vb)
