For fitness people, a reasonable lunch should be to bring some fruits and vegetables that are easy to eat raw, such as cucumbers and tomatoes, to supplement trace elements such as sodium and potassium consumed during exercise, and a cup of yogurt to supplement protein, which is an essential source of heat for the body. Then, eat two pieces of bread or coarse grain biscuits and, if possible, add an egg, so that the nutrition will be more comprehensive. If you eat instant noodles, you can eat some fruits, vegetables and eggs at the same time, so that the calories, protein, fat, vitamins and trace elements needed by the human body can be balanced. However, it should be noted that a light diet is the main diet after fitness, and it is not advisable to eat too much. It is advisable to eat seven minutes full and eat half an hour after fitness.
