Brother, I'm from Shandong, too! Don't give yourself too much unnecessary pressure just because some peers have grown to 175CM. You are only 14 years old. Boys usually don't stop changing their height until they are around 20. So with your current height, it is optimistic to increase 1CM a year. Boys, don't care too much about dieting. For boys, it generally does not exceed 70KG, which does not affect your handsomeness. So eating too much is not good, and dieting is not necessarily good!

14 years old, during which the balance of nutrition is very important. So pay attention to diet and ensure three meals. Under normal circumstances, there is a height difference in the morning and evening. What you said about 2~3 cm is within the normal range, so don't worry.

Also, after entering adolescence, there may be problems such as nocturnal emission, disobedience of younger brother and erection. That's how we boys get here. Don't worry too much about our adolescence. Pay attention to personal hygiene and psychological adjustment, I believe you will have a happy adolescence!
