First of all, I feel that 40 minutes is very short, and it is best to jog 1 hour or more. In addition, add enough water every day. If there is not enough water, your body will remind you to extract more water from food. Eat slowly, chew slowly and prolong the time as much as possible. Generally, you won't feel hungry after 15 minutes. You can do an experiment. You can eat a bowl of rice when you eat, and then put down your chopsticks and do something else, such as playing computer. After a while, you will feel that you have eaten and are not hungry. Of course, this is only temporary. If you are really hungry, you can use an apple or a glass of water instead to make your stomach feel full.
Face-lifting, there is really no good way. Generally speaking, if the body loses weight, the fat on the face will be consumed by the body, but the face should be the last effective. In my case, my face is the last thin.
Exercise to lose weight, it is important to persist! I hope my answer can help you.
