I have been engaged in sports for many years as a sideline and have helped many friends who come to our gym to lose weight quickly.
Usually, fast weight loss must be combined with exercise, and it is difficult to control it by diet alone.
Personal recommendation:
Morning: jog for 50~70 minutes.
Evening: 50~70 minutes' walk.
Diet:
Completely replace the staple food with fruits and vegetables. You can eat some eggs and drink some yogurt.
As long as you avoid eating rice and greasy food, there is nothing else to pay attention to.
As long as we persist, girls who come to our place to lose weight can generally lose about 10 kg a week, and boys can lose more.
If your request is not so big, ask for about 5 kg, which can save the exercise at night.
PS:
Don't step into the misunderstanding that losing weight quickly will "rebound". Most of the rebound only happens to puffy people.
Don't regain your appetite immediately after losing meat. In addition, if it is not puffiness, don't be too afraid of rebound.
I wish you success!
