If you have enough perseverance, not only 15 kg, but also 25 kg is possible. But losing weight so soon will rebound quickly, and it is very bad for your health. If you lose weight successfully, continue to insist on not overeating and exercise, and you won't rebound.

An egg and a cup of honey for breakfast. Have a full lunch for 3-5 minutes, eat more vegetables and don't eat greasy food. You can have an apple instead of dinner. In fact, these foods can be chosen by themselves. Just the right amount. Don't fill your stomach five hours before going to bed. Quit all snacks. If you accidentally eat too much or eat high-calorie food, imagine that your persistence will be in vain at least one day. This will make it easier to control your mouth next time.

Exercise should be done every day: skipping rope continuously 1000 times. 200 sit-ups Hula hoop for half an hour. Or walk for more than half an hour. Select at least two actions. You can choose your favorite exercise method, but you should do it for more than half an hour at a time, and sweating is the best. Because you can't burn fat for half an hour, it's no use doing it.

The less you eat, the better. The less you eat, the better. Eat more vegetables, eat less staple food or not. If you are hungry, eat a fruit or drink a cup of honey. Honey moistens intestines, helps you lose weight, and is good for your skin. Don't let yourself feel full at any time. When your stomach is growling, imagine that fat is being consumed, so it is easy to stick to it.

There is another point that I have always insisted on. Don't sit still after dinner. Stand up straight against the wall 15-30 minutes. Help digestion, won't grow belly, but also stovepipe. After a long time, you will form a habit.

If you persist in this way for a month, the effect will be obvious, but your face will lose its luster and your head will be dizzy. This method is extreme, but it is the only way to lose weight quickly without taking medicine. If you don't have enough perseverance, it is very difficult to do it. I hope you succeed.

Losing weight is a long-term and arduous project. Even if you succeed, you should pay attention to maintaining some good habits, otherwise it will be much easier to rebound than to lose weight. And much faster.

I hope I can help you, wish you a happy life and hope to adopt.
