Low Carb vs Low Fat – Not Just Calories Count

Not all calories have an immediate effect on our weight

Dieter is like sand at the sea and new is added every week. Who will keep track of? In a recent large-scale nutrition study, various diets have been observed for a long time to identify which diet is ahead when losing weight. It also turned out that losing weight is not just about calories. Although all participants received the same number of calories over 20 weeks, a certain group decreased most.

A US research team from the Boston Children's Hospital and Framingham State University observed and controlled obese individuals over a period of 20 weeks while following prescribed diet plans. During this period, body weight, insulin levels, metabolic hormones and calories were measured periodically. It showed that weight loss is more important than just the number of calories. The results of the study have recently been published in the magazine "The BMJ".

Obesity and obesity – an increasing health problem

Obesity 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: Overweight can cause depression). Doctors and researchers seek desperately effective methods to counteract this. Dieter is a good measure of losing body weight, but for many, success is short-lived. A few months later, the weight is back, sometimes even more than before.

What 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. Researchers compared three diets to a group of obese subjects over a 20-week period. Nutrition was provided entirely by the university to ensure that all participants receive the same number of calories.

Three diets – Same calorie count, different weight loss

The 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 calculation was exactly the same in all three groups, participants from the low carbohydrate group showed the most decreased and long-term weight loss.

Calories are not equal to calories

The researchers concluded that calories from carbohydrates lead to faster fat storage. "Carbohydrates increased the insulin levels below the diet and drove fat cells to store more calories," says research director. With. David Ludwig in a press release on the study results. The increased storage would be available to the rest of the body less calories. The result: Metabolism slows down and hunger increases, so the nutritionist. Without this condition a rapid weight gain can occur.

Weight loss in the low carb group was significantly greater

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

Carbohydrate Insulin model

The study shows that the so-called carbohydrate insulin model is suitable for the treatment of obesity. The researchers could show that the intake of carbohydrates leads to a higher release of insulin. This promotes the build-up of fat stores, slows down metabolism, inhibits saturation and promotes the feeling of hunger. "Our observations challenge the belief that all calories are the same for the body," concludes the second director Cara Ebbeling. (Vb)
