Low-carbohydrate diets may consume more calories than regular meals

Low carbohydrate diet refers to a diet that limits the intake and ratio of carbohydrates for the treatment of obesity and diabetes, or for dieting. This diet method of replacing energy ingested by carbohydrates with protein or lipid has been shown to possibly affect the amount of calories consumed in the body itself.

Low-Carb Diets May Burn More Calories

Research teams such as Boston Children's Hospital and Harvard Medical Graduate School jointly conducted experiments to demonstrate the "carbohydrate-insulin model" on obesity. Based on the idea of ​​this carbohydrate- insulin model, the higher the " Glycemic index (GI value)" representing the degree of increase in blood glucose level for each food, the harder it is to consume excess calories, the fat cells in the body become excessive calories It is said to tend to incorporate.

Experiments conducted in a short-term cycle, such as within the past two weeks, found that there was no significant difference in calories consumed between high carbohydrate diets and low carbohydrate diets. Therefore, the research team conducted an experiment over a long span of about 5 months and investigated whether the results supporting the carbohydrate-insulin model appear.

In the study, 164 adults who were diagnosed as "obese and need to reduce body weight by 10%" participated. Three kinds of diet regimens of 20%, 40%, 60% are allocated to each participant at random "percentage of carbohydrates out of the total calories" and the participants' fat burning rate and accelerometer The momentum measurement etc with wearing was carried out. Participants who were assigned low-carbohydrate diet increased caloric intake from fat compared to high-carbohydrate diet, but with regard to protein, sodium, and sugar, all participants had the same level of intake He seems to have been adjusted.

As a result of 20 weeks of experiments, the research team found that even among participants with similar weight, participants who had low carbohydrate diet had more calories than participants who took high carbohydrate meals I discovered what I'm consuming. Participants who had a low carbohydrate diet consumed 209 to 278 kcal of calories more than those who took a high carbohydrate diet even if there was no difference in the amount of exercise per day. The research team says that if the same effect lasts for 3 years, we get about 20 pounds (about 9 kg) in weight difference even though it is the same momentum at the same caloric intake.

In addition, it is said that the most frequent consumption of this calorie was participants who "secrete high levels of insulin after ingesting glucose ". When a person secreting high levels of insulin took a low carbohydrate meal, he consumed 400 kcal more calories per day than those who did not.

This finding is consistent with the carbohydrate-insulin model, and David Ludwig of the Boston Children's Hospital who studied, "There will be a difference in the amount of calories consumed depending on the type of caloric intake.The low-carbohydrate meal Will reduce the amount of insulin released and reduce fat cell activity to increase calorie consumption. " Mr. Ludwig thinks that the calories in the blood that are not trapped in adipocytes are easy to use due to the brain and muscles and are likely to be consumed.

However, in recent studies , "lifespan shrinks as compared to those who take moderate carbohydrate diets when taking high-carbohydrate or low-carbohydrate diet" has also resulted, low carbohydrate diet has long-term It is not known what effect it will have on it.

Moreover, it seems that this research alone can not say that "you can consume more calories just by switching to a low-carbohydrate meal with a conventional meal." Although the research team provided as similar a meal as possible among the groups, it is impossible to deny the possibility that the nutrients which could not be adjusted by the research have influenced the results. Therefore, the research team thinks that further experiments are necessary to elucidate the mechanism.
