First of all, talk about the color change of fat. There must be no oil in the food. Sometimes every bite of food needs to be rinsed with boiling water before eating. In fact, fat is an essential nutrient for human body, and its total intake accounts for about 20% of total calories. Even if you want to control your diet, you should keep your fat intake above 10% to meet your body's needs.

Because fat is an important raw material of human cell membrane, if fat, especially the fat that must be ingested through external food, lacks inhibition on cell membrane repair and metabolic function. Over time, the function of cells will be damaged, and health will naturally be damaged. In order to meet the needs of the body, the correct way is not to refuse the intake of fat, but to reduce the intake and increase some necessary fatty acids, such as unsaturated fatty acids.

Not eating staple food and thinking that staple food is high in calories is an important cause of obesity. Generally speaking, staple food refers to foods containing a lot of carbohydrates, such as rice, pasta, potatoes, sweet potatoes, etc., which can provide a lot of carbohydrates. Sugar will be decomposed into monosaccharide (glucose, fructose) and disaccharide (sucrose) after entering the human body, and then it will be absorbed and utilized by the human body. Among the three energy substances (sugar, fat and protein), the cleanest is the decomposition of sugar, which only produces carbon dioxide and water after complete decomposition, while the intermediate products of fat decomposition, intermediate products of protein and final products are obviously toxic, which is extremely harmful to health.
