I have a friend who is also a boy. Because no girl likes it, she is determined to lose weight! He lost 40 kg in one semester, and now he is 183cm, 135 kg. I advise you not to lose too much, so my friend has lost a lot of weight, not as good as before. I feel that a gust of wind can blow him down. Students who used to be like saplings all said, "Wow! Are you taking drugs? ! "He won't eat unless he is really hungry! At school, too, he told me that when he was hungry, he squatted down and stood up, and his eyes were dark! He is still taking diet pills. At first, he ate fruit tea to make him thin. Then I ate intestinal bacteria and collagen. He is extremely thin! If you are an adult, you can take some diet pills. He runs 5000 meters every day during the summer vacation. If you can't keep running, you can walk for an hour or two every day. Walking with friends will go faster. Now I just walk with him for 2 hours/day. But walking is not as effective as running. I don't suggest you lose weight for a few days or something, because you lose weight quickly and come back soon! And it may lead to malnutrition, anemia and other symptoms. It takes a long time to prepare a diet meal! If you like noodles, you'd better get rid of them. Let's eat rice. You can put it in the morning or eat less if you want. Eat more coarse grains, stick to the habit of going to bed early and getting up early, and eat three meals a day! But eat less, don't drink beer, eat instant noodles. Don't stay in front of the computer and TV for too long. The premise of losing weight is not constipation! I think you should know some common sense. According to my years of experience and other people's actual combat results, I will give you the answer. Remember, if you succeed in losing weight through exercise, you can't give up exercise, or fat will come to you! All right, that's it. I wish you success in losing weight!
