What is more Slimming: Low-carb or low-fat diet?
American researchers who tested hundreds of participants found the answer to which diet leads to the most significant drop in weight - low-carb or low-fat. The results will disappoint the fans of both methods. The findings published in the new issue of JAMA.
The study, which lasted a year, involved 609 men and women aged 18 to 50 who were overweight or obese. They divided into two groups: one was asked to reduce the amount of carbohydrate in the daily diet, and the other the amount of fat. Subjects were instructed to enrich the menu with vegetables and cut as much as possible in processed foods. On average, participants consumed about 600-500 fewer calories than they had before the study.
At the end of the year, the results showed that there was no significant difference in the mean weight loss of both groups: in the low-fat diet group, the average weight loss was 11 pounds (4.9 kg), while in the low carb group the average decrease was 13 pounds (5.8 kg).

In the meantime, researchers speculated that specific genetic and metabolic markers in previous studies might predict who will succeed and which diet. However, the current study showed that this was not the case: about 30% of the subjects had a "genetic signature" that was supposed to indicate success on a low-fat diet, while 40% had a "genetic profile" Carbohydrates.
However, the study found no correlation between the genetic makeup and the chances of success in each diet. The researchers also tested insulin resistance, previously seen as predicting success in different diets, but this time too, no correlation was found between insulin resistance and success in any diet.
"It was very nice to know through a simple genetic test which diet is best for you," said Dr. Christopher Gardner, head of the team at the Stanford Research Center in the US, "but that's not the case. Your relationship with food and thinking about what you eat. "
Dr. Gardner recommends eating less sugar, less processed flours, and more vegetables: "Go for whole foods - whether it's salad from wheat grains or beef fed in the grass. From both groups, we heard from people who lost weight that we helped them change the relationship they developed with food, and now they eat more intelligently and think about what they eat. "
