If you 14 years old, you will go to junior high school, right? About 80 kg is almost enough 150cm. Not thin and not good-looking.

Now that you are grown up, you must never go on a diet to lose weight, or you will not grow tall.

I said, you should eat regularly, eat well at breakfast, eat well at lunch and eat less at dinner. What about two hours before bed? Do not eat.

Or drink yogurt.

Eat more fruits and vegetables at ordinary times, drink more water every day, and keep the stool unobstructed. Every day, the stool is smooth, and with it, you won't get fat.

Don't go on a diet to lose weight, at least until college.
