Dieting and exercise are the best ways to lose weight, but you said you didn't have time to exercise. You are now 18 years old, and you are not suitable for taking diet pills. It is normal to lose weight when growing up. If you insist on pursuing less than 45 kg, I suggest you try cupping to lose weight. This is healthy, without any pain. Just pay attention to your diet for the first few days. You can only eat beef jerky and soybean milk. How many? Cupping is also effective for losing weight. My cousin tried it and lost 10 kg in a month. And cupping will make her want to lose weight. It won't be said that thin breasts and thin breasts have the same side effects as taking medicine. This is healthier.
I also lose weight by doing aerobic exercise. I went to the gym for a month in the summer vacation. I lost 7 pounds in the first week, but only 95 pounds. I drank too much green tea!
I also tried to eat green tea powder mixed with yogurt, and I was very thin, but it was hard to accept when I first ate it, and it was a little astringent. Just take it twice. Eat this cup every morning and have a normal rest. I don't exercise at all. I lost 5 pounds after eating for 5 days, so I eat green tea powder mixed with yogurt every day when I get fat. This is the method I used to lose weight. I hope it will help you.
