You are now in the fastest growing period. The most important thing in diet is to supplement enough energy, protein, vitamins and trace elements necessary for human body to ensure the rapid growth of body and mind. Besides, people usually get a little fatter in winter, depending on your situation. Instead of getting fatter in winter, they become thinner. This shows that if you are not too nervous and anxious to affect the absorption of nutrition, you will probably "make ends meet" and the nutrition will not keep up. It is reasonable for you to worry about eating too much at night, but don't be too entangled. Grade three and grade three are the two stages with the greatest stress in life. They consume a lot during the day and naturally eat more at night. You can consider eating more in the morning according to the study intensity of each stage every day, and supplement some foods such as soybean milk, yogurt and eggs (you know that we orientals don't have the eating habit of eating dairy products for thousands of years like westerners and northern nomads, and it is difficult to achieve the same milk absorption and utilization rate for decades. According to Japanese and Koreans, their height has increased significantly after drinking milk for at least 30 years. Breakfast can reach the proportion of 35%, lunch can consider the proportion of 35%-40%, dinner can naturally be more scientific, dinner can eat less greasy food, it is best not to eat too salty, and eating more fruits and vegetables is also an important way to supplement vitamins. In fact, I personally think that eating fruit may not be as good as taking multivitamin tablets, because many vitamins and trace elements must be eaten together to have a higher absorption and utilization rate. Nowadays, it costs more to take a multivitamin tablet every day. At the peak of adolescent growth, it is most effective to supplement adequate vitamins and essential trace elements. If the figure and figure are basically stereotyped, I am afraid that eating too much will have no effect. It's hard to gain weight in grade three, unless you have a full meal, it's hard to gain weight. In addition, weight gain does not necessarily mean gaining weight. If you are tall, the proportion of bones will increase and become heavier. Don't worry about food. If you find yourself with fat, it's time for you to reduce your appetite, but just cut down on the staple food. If it can't be reduced, it's also a good idea to increase some exercise. Finally, I wish you good grades in the senior high school entrance examination and play your own level in the exam!
