Don't! If you go on a diet, you will rebound if you can't stick to it. I personally know it. After a long time, I have a bad appetite and always hurt. Just eat less. Read every meal, but eat less. If you are not too hungry at night, you don't need to eat. Eat more breakfast, eat less at noon and don't eat at night. If you eat at night, eat at 5 or 6 o'clock. After that, you will get fat. Don't lie down immediately after dinner. Don't miss this meal. Eat a lot at the next meal. Eat to the eighth floor. Drink more water, and you won't be hungry too fast. I weigh 84 kg now. Otherwise, if you go to the gym to exercise, you will lose a lot of sweat, and it will be bad if you don't replenish it in time. Don't go on a diet too seriously. If you don't succeed in dieting and losing weight, your physical fitness will get worse, your whole body will have no vitality and your skin color will be unhealthy.
