I've seen colleagues wear thin waist and thin legs before, and they exercise with plastic wrap just like you, but it's not vaseline. It will have some effect after a while, but you should stick to it.

Personally, if you want to lose weight, hunger strike and drugs are not ideal. They are all persistent. Why bother?

If you have the habit of eating supper, I have experienced it personally. When I am hungry, I will give up dinner and never eat again. Of course, I can eat some fruit. I will try to drink less water at night and eat during the day. Remember to eat more and eat less. As long as you are not full, you can eat whatever you want. The most important thing is not to eat supper. Stick to it for half a month to ensure the effect. After a long time, you will naturally lose weight. Of course, if you like sports, it will enhance the effect.

Many friends have used my method and it works. The landlord can try it and hope it will help you.
