Losing weight has nothing to do with trans fatty acids, but to lose weight, you need to eat less fried foods (containing more trans fatty acids). Weight loss should be combined with reasonable diet and exercise in order to lose weight correctly and healthily. The following is the introduction of trans fatty acids:

Trans fats, also known as trans fatty acids and trans fatty acids, are unsaturated fatty acids (monounsaturated or polyunsaturated).

Different from other edible fats in the diet, trans fats are harmful to health and are unnecessary nutrients for the human body. Eating trans fats will increase the risk of coronary heart disease, because it can increase "bad" low-density lipoprotein cholesterol and decrease "good" high-density lipoprotein cholesterol. The liver cannot metabolize trans fat, which is also one of the important reasons for hyperlipidemia and fatty liver. Health authorities all over the world recommend reducing trans fat intake as much as possible. It is generally believed that partially hydrogenated vegetable oil poses a greater risk to health than pure natural vegetable oil. In the report "Prevention and Control of Non-communicable Diseases: Implementing a Global Strategy", the World Health Organization has repeatedly reiterated the need to "gradually eliminate trans fatty acids". The United Nations Food and Agriculture Organization and the World Health Organization suggest that the diet should contain only a very small amount of trans fat, which is lower than the daily calorie intake of 1%. For an adult who consumes 2000 calories a day, this amount is equivalent to no more than 2g a day.
