You can eat less for dinner, you must eat breakfast every day (on time and in quantity), you can choose low-calorie things for lunch, you must eat more fresh fruits and vegetables for dinner, and eat less staple food. The staple food must not be given up!
In addition, if you want to take diet pills, I recommend Olex's OB protein slimming agent, which can effectively control appetite and has no great side effects on human body. This is what I'm using now. I lost weight in 2 weeks 10 kg. In fact, most of the side effects on the Internet are smoke bombs. Just looking around.
