The most important thing is to control appetite.
Just eat 7-8 minutes full.
The most important thing is: be sure to have breakfast. If you are used to eating breakfast in the morning and are full at noon, you will naturally not be hungry at night. Being unable to lose weight means eating too much meat. Dude, I can't digest it.
Besides, don't eat supper. If you are used to eating supper, you will not lose weight.
If you really can't carry it, you can use fruit instead of supper.
Then there are sports, playing basketball, running, taking a walk after dinner and so on.
Persistence is the most important thing. I believe you can lose weight and reach your ideal figure.
