Eat 7 or 8 minutes full at noon, eat less pork, eat beef and skinless chicken. Eat more vegetables (low in calories and containing dietary fiber)
In the evening, if possible, eat a cucumber and tomato. If you can't adapt at first, you should halve your usual appetite and gradually reduce your intake at night.
Of course, you should also cooperate with sports, play basketball and football with your buddies, which should be your boy's favorite sport. Now I can go swimming in summer, which is cool and slim. You can also do some push-ups before going to bed at night. It's good for boys to practice some muscles.
Drink plenty of water (try not to drink) to help excrete toxins from the body. You can also drink Pu 'er tea or lotus leaf tea, both of which are helpful to lose weight.
In the morning, you can drink a cup of cold boiled water or light salt water on an empty stomach, which is beneficial to defecation.
That's about it. You have a good height. You will look strong if you practice some muscles.
Ps: You are as tall as my best male friend, hehe. I wish you success ~
