I used to know a boy. He said that he reached 145 in high school, and the whole person looked round. Finally, after graduation, in order to pursue a sister, the sister disliked him and lost 30 pounds in a rage.
The method he told me is high-intensity exercise every day, which is not suitable for everyone. It's not that your heart can't hold on, but that your body can't bear it at all. But if you want to lose weight, exercise is still necessary.
You can go out for a morning run every morning until you sweat and get hot. Don't feel tired, just stop. Go back and have another breakfast, which is not high.
You should work at other times, so use the evening time to exercise. You can go to the gym every night and find a coach who specializes in slimming. I think if there is a professional sport that is meaningless to me, I will lose weight faster.
Besides fitness, diet is also very important. The daily intake should not exceed 1000 calories. This diet record can be downloaded to an app, which will tell you what you eat every day and how much fat you have. However, if you want to lose 20 pounds and eat less, it is enough to meet your basic needs. Don't eat anything after five in the evening. Don't eat anything except water.
My sister used to eat mixed vegetables to lose weight, but she didn't touch greasy things. Later, she successfully lost dozens of pounds, but the time was not so fast. So you can't eat those greasy things when you lose weight.
I lost so much weight at once that my skin couldn't bear it. You can do some skin care properly, otherwise you will form fat lines in the future.
If you do this every day, you will feel very tired at first and feel that you are going to die. So everything depends on whether you can persist.
