Is it a good idea to use a hypnotist to help me lose weight?

It’s not clear from your question if you’re asking about hypnosis in general, or specifically the type of hypnosis that involves using an external source of suggestion. If it’s the latter, then I would say no. Hypnotists are trained professionals who can provide very specific and powerful suggestions for changing behavior, but they cannot be trusted to do so responsibly. For example, there have been many documented cases of people being harmed by hypnotists who were trying to help them lose weight.
