If porridge is added, all grains should participate. You can eat eggs in the morning, change milk into soybean milk in the morning, and drink milk at night. It's better if the beef at noon is not fried, and it's not good to eat too much fried food. Besides beef, pork and mutton should be added, as well as white meat such as chicken, duck and fish. Also, your children eat too little, which is not enough for children with long bodies. Don't drink too much milk, it won't be absorbed. Pay attention to sleep besides diet. It is not too much to exercise for half an hour every day. Teenagers like sports. Every day, they just play football and basketball with their friends for an hour or two, so half an hour is not much.

Let me tell you something my parents made me eat when I was growing up:

Morning: porridge (or soybean milk), two eggs, vegetables (different every day, depending on nutrition and my diet preference, but I'm not picky about food), sometimes steamed buns, steamed buns (in China, of course), pies, egg cakes, etc. My mother studied all kinds of tricks to make me eat more.

Morning: fruit (my mother always gives me a fruit for me to eat between classes at school, which can be different every day), water (drink as needed, ml is not limited)

Noon: According to the custom in China, the staple foods are noodles, rice, steamed bread, cakes, porridge, steamed bread, jiaozi and noodle soup. My mother won't take the same sample for a week at most. In addition to vegetables, she can also cook ribs, fish, chicken, duck, beef and other nutritious meat. But these meats are not cooked every day, basically once or twice a week. Vegetables are available every day, and the varieties of vegetables are changed every day, mainly cooking, without pepper, less oil and salt and more vinegar.

Afternoon: fruits, water and other snacks (mainly my hobby, but I don't like sweets, mainly dried fruits and various biscuits I choose myself)

Evening: It's about the same as noon, but I eat a lot. Sometimes I don't have enough food.

After dinner to bedtime: fruit (whatever you like), milk or powdered milk, Gao Legao or yogurt.

I don't think we can give Amway to our children.

If your child 17 years old eats according to your diet, I don't think he is full at all. Growing children eat more than adults. I ate a lot at that time. Sometimes a person can eat a fish, staple food and other vegetables, and then he will still be hungry. More exercise can make you grow taller. Also, your children eat too carefully and don't eat too much, so some trace elements or some nutrients will be biased.
