The first thing to lose weight is to shut up. Breakfast and lunch can be eaten normally, and dinner is eaten earlier, such as 5 pm, or no staple food at all. Use some fruits and vegetables instead, such as cucumbers and tomatoes. Resolutely put an end to the habit of eating snacks, especially high-calorie snacks, including sugary drinks. Exercise 1 to 1.5 hours every day, or walk five kilometers every day. Others ride bicycles and play badminton in square dance, all of which are quite good. The rest is to give time, and as time goes on, the weight will be light.
