A recent study on nutrition indicates that overeating may not be the main cause of obesity. The research was conducted by 17 internationally renowned scientists in the field and was published in the American Journal of Clinical Nutrition on September 13. The conclusions of the paper are supported by the limitations and deficiencies of the research energy balance model (EBM). So far, EBM is the most common and main method to determine the cause behind obesity. However, researchers believe that the carbohydrate-insulin model (CIM) is a better way to define the causes of obesity.

EBM believes that obesity is an energy balance disorder, but ignores many biological mechanisms. According to the century-old model, weight gain is a direct result of energy consumption exceeding the body’s consumption. Due to the continuing pandemic, a sedentary has become the new normal today, resulting in less and less energy output. Therefore, the body begins to store energy in the of fat.

EBM explain some of the normal metabolic processes of the human body. The study pointed out that “during the growth spurt during adolescence, as the body’s energy reserves increase, energy intake exceeds consumption. Does increased consumption drive growth or growth drives consumption increase?” The researchers said that EBM completely ignores the biological storage of body fat. The impact of the mechanism.

For a long time, excessive consumption of high-calorie foods has been considered the only cause of obesity. However, recent studies have shown that “weight is controlled by a complex and interconnected system involving multiple organs, hormones, and metabolic pathways.” This means that many factors can lead to weight gain or fat gain.

The alternative CIM model considers hormonal and metabolic factors when studying the causes of obesity. Like EBM, it also links food to increased fat. But it pointed out that weight gain is more related to the composition of food than food intake. That’s because different food components trigger different biological in the body.

CIM links fat deposits in the body to hormonal responses. When eating a diet with a high glycemic load, the body’s hormones send signals to the cells to store more calories. However, this fat storage mechanism deprives muscles and the energy required for metabolic processes. Therefore, although the body consumes more calories than it consumes, it still needs more food intake.

This study urges more research in this area to determine the causes and effects of obesity.
