If you are fat: don't run if you are fat.
I think if you don't have perseverance,
You will rebound and eat a bowl of rice a day.
Take a walk and chat with your best friend after dinner.
Many fruits
Do more homework before going to bed. If you don't like writing.
You can spend more time in solve riddles on the lanterns or something.
Because the brain consumes energy in the body when thinking.
You can run when you reach the standard weight.
Or other outdoor sports, don't take diet pills or something that is bad for your health.
