General fat can't be converted into protein, but excess protein may be converted into fat, leading to obesity. In order to avoid this situation, it is necessary to strictly control the intake of protein during weight loss, so as not to affect the weight loss effect, and at the same time, not to affect one's own health. In addition, if you want to lose weight quickly, you need to cooperate with doctors to improve the weight loss effect.

Lipid is a general term for oil, fat and lipid. The fat in food is mainly fat. Generally speaking, liquid at room temperature is called oil, and solid at room temperature is called fat. Fat is composed of three elements, C, H and O. Fat is a triacylglyceride composed of glycerol and fatty acids, in which the molecule of glycerol is relatively simple, but the types and lengths of fatty acids are different. Fatty acids are divided into three categories: saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids. Fat is soluble in most organic solvents, but insoluble in water.

Protein is an essential nutrient for human body, so we should pay attention to the intake of high-protein food in our daily life. Foods in protein are generally divided into plant protein and animal protein, and the types and proportions of amino acids contained in animal protein are more in line with human needs, so the nutritional value is higher than that of plant protein. Common high-protein foods in life include dairy products, chicken and eggs.

Protein's Physiological Function and Its Importance

1, protein is the material basis of all life and the basic component of tissues and cells. Adults need to update about 3% of protein every day.

2, constitute a variety of substances with important physiological functions in the body. Enzyme catalysis: The human body is like a complex chemical plant, and all physiological metabolism and chemical reactions are completed by enzymes. Hormone regulation: such as growth hormone, sex hormone, adrenaline, etc. Immunity of antibody: antibody is a kind of immunoglobulin with defensive function, which can improve the body's resistance and protect the body from bacteria and viruses. Bioactive substances such as enzymes, hormones and antibodies in human body are all made of protein.

3. Maintain and regulate the acid-base balance and plasma colloid osmotic pressure. If there is a long-term lack of protein in the diet, it will not only destroy the acid-base balance in the blood, but also lead to the decrease of colloid osmotic pressure in the plasma, and the water in the blood will go deep into the surrounding tissues, resulting in nutritional edema.

4. When the intake of other productive nutrients is insufficient, replenish energy for the body.
