1, the dining arrangement is "five meals a month", that is, five times a day. The proportion of five meals is that breakfast accounts for 20% of the whole day, morning meal accounts for 10%, lunch accounts for 30%, afternoon meal accounts for 10% and dinner accounts for 30%. 2. The composition of daily diet recipe is: moderate protein, low fat and high carbohydrate content. The ratio of the three main nutrients should be about 25∶20∶55. Steamed bread, noodles, rice and other staple foods and sweet potatoes, oats, potatoes and other carbohydrates are high in content, which can be used as the first choice. Protein is the most important source of nutrition for muscle growth. Protein, a bodybuilder, should mainly eat fat-free or low-fat foods, such as skim milk, egg white, fish, skinless poultry and steak. Fatty acids that are needed to maintain normal human growth but cannot be synthesized in the body are called essential fatty acids, which are mostly found in olive oil, corn oil and soybean oil. Moderate intake can not only meet the needs of the body, but also will not increase the incidence of cardiovascular diseases. 3. Eat more alkaline food. Normal body fluids are weakly alkaline. After physical exercise, sugar, fat and protein in the body are decomposed in large quantities, resulting in acid substances such as lactic acid and phosphoric acid, which makes people feel sore in muscles and joints and mental fatigue. At this time, you should eat more alkaline foods such as vegetables, sweet potatoes, oranges, apples, etc., and keep the basic balance of pH in the body to eliminate fatigue caused by exercise as soon as possible. In addition to vegetables, fruits and other alkaline foods, we should also supplement a variety of vitamins necessary for the human body to supplement the loss of metabolism and sweating.
