maybe the term "cut loss" is already familiar to the residents of this forum especially in the world of trading. I have experienced a loss of almost 70% more than my assets due to cut loss and that almost made me like no life. What is the way to make a good and correct cut loss, so that it doesn't happen again? are there any tips?

I want to ask about weight problems. I have a weight that is not ideal (thin). I have tried several times, like drinking 2 milk every day, exercising 20 minutes/day. But still it doesn't add to my weigh .Do you have other tips for me?
