There are two main types of fat in the male body: subcutaneous fat and visceral fat. Subcutaneous fat is located under the skin, mainly in the buttocks and thighs, and has a role in energy supply and mechanical protection. Visceral fat surrounds the organs in the abdomen and directly affects glucose and lipid metabolism in the body. Excessive accumulation of subcutaneous fat not only leads to obesity in appearance, but also increases the burden on other tissues and organs of the body, while excess visceral fat increases the risk of chronic diseases such as cardiovascular disease, diabetes and metabolic syndrome. Men usually have a higher percentage of visceral fat than women, which is largely attributed to changes in hormone levels in the male body, particularly the role of testosterone in regulating fat distribution and metabolism. A gradual decline in testosterone levels with age will result in an increase in body fat, especially visceral fat, in men. There are two different functions of fat cells in the body: white fat and brown fat. White fat mainly stores energy, while brown fat contributes to energy expenditure and metabolic regulation through thermogenesis. It has been found that the amount of brown fat in the human body gradually decreases with age, and the amount of brown fat in the male body is usually higher than that in the female body, but there are significant differences in its activity and efficiency among different individuals. Factors affecting male obesity mainly include high-calorie diet, lack of exercise, psychological stress and genetic background, etc. Male sex hormones, such as testosterone, also have an important role in regulating fat metabolism. Obesity has a profound impact on men's health and is an important risk factor for chronic diseases such as cardiovascular disease, diabetes mellitus and metabolic syndrome, and may affect male sexual function and fertility.

Adhering to the idea of treating the future illnesses in TCM, GENSUNBIO attaches importance to the key significance of weight loss and fat lowering to human health and disease prevention. On the basis of scientific analysis of the characteristics of fat distribution and energy metabolism in men, GENSUNBIO use modern biomedical engineering technology to systematically carry out the nutritional analysis and functional evaluation of natural medicinal raw materials, to explore the potentials of their role in regulating lipid metabolism in women and inhibiting the accumulation of fat, and reveal the regulatory mechanism for the transformation of white fat to brown fat, providing a reference for determining the personalized weight loss and fat lowering program suitable for men's physique.
