Low Carb Vs. Low Fat – not only calories count

Not all calories have an immediate effect on our weight

Diets are like sand by the sea, and new ones are added every week. Who should follow? In a recent large-scale nutritional study, different diets were observed over a longer period of time to determine which diet is premature when slimming. It also turned out that weight loss is not just calories. Although all participants received the same number of calories in 20 weeks, one group decreased the most.

An American research team from Boston Children & # 39; s Hospital and Framingham State University has observed and controlled overweight people over a 20 week period, following the recommended diets. During this time body weight, insulin levels, metabolic hormones and calories burned at regular intervals. It showed that losing weight is more important than just 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 is conducive to many heart diseases, hypertension, diabetes and depression (see: obesity can cause depression). Doctors and scientists are desperately seeking effective methods to counteract this. Diets are a good way to lose weight, but for many people, success is short-lived. A few months later, the weight returned, sometimes even more than before.

Which diet is the best for slimming?

Which diet is the most effective for long-term weight loss? This question was answered by the American research team. Researchers compared three diets with a group of obese people over a 20-week period. Nutrition was completely provided by the university to provide all participants with 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% carbohydrates in the second group and 60% carbohydrates in the third group. Although the number of calories was exactly the same in all three groups, participants in the low carb group showed the longest weight loss and durability.

Calories are not equal to calories

Researchers concluded that calories from carbohydrates lead to faster fat storage. "Carbohydrates raised insulin levels during the diet and led fat cells to store more calories," says research director. med. David Ludwig in a press release about research results. Increased storage would be available for the rest of the body with fewer calories. The result: metabolism slows down and increases hunger, so nutrition expert. In addition, the condition may be rapid weight gain.

Weight loss in the low carbohydrate group was significantly greater

As the scientists documented, the total energy expenditure in the group with a low carbohydrate diet was the highest in 20 weeks. With the same average body weight and calorie intake, participants who used a low carbohydrate diet burned about 250 kilocalories a day more than those with a higher carbohydrate intake. People who had high insulin levels early in the study were even more drastic. In this case, the low-carb group burned up to 400 calories more per day.

Carbohydrate insulin model

The study provides evidence that the so-called carbohydrate insulin model is suitable for the treatment of obesity. Researchers have been able to show that carbohydrate intake leads to higher insulin release. This favors the accumulation of fat stores, slows down metabolism, suppresses satiety and promotes hunger. "Our observations undermine the belief that all calories are the same for the body" – sums up the second director of research, Cara Ebbeling. (Vb)
