I think it's great that you can keep turning the hula hoop every week.
In this way, you should be able to lose 10 A Jin month, because you only eat fruit at night.
But eating too much watermelon is not good.
You can read the negative news about eating too much watermelon on the Internet.
If you can stand for half an hour after dinner every day,
Or walk around,
It is more helpful to help digestion.
I wish you success ~ ~
