You can't lose weight at once. There is a platform. Do you do aerobic exercise for an hour? If so, then stick to it. Eating less doesn't necessarily mean losing weight. Eat well in the morning, eat well at noon, eat less at dinner and eat 70% at night. It also depends on how many calories you eat, like a hamburger and two bowls of rice. It must be more meals, but hamburgers have more calories, so it's better to eat less greasy ones. Eating more vegetables will definitely make you thin.
