For a month, do aerobic exercise for half an hour every day. You can definitely lose weight, but that's under the condition of proper diet. Because after exercise, your appetite may be better. Eating too much will not make you thin, but will make you stronger and healthier.
If you want to lose weight, reduce the amount of oil in the dishes you cook every day and reduce your appetite.
Losing weight is not calculated by how much you lose every day. This can be seen in at least one week, and with proper dieting, you can lose 3-4 kg a month.
