Hypnosis for some people to lose weight through hypnosis is possible for some people but not everyone loses the desired weight or any weight at all when they become hypnotized.
To lose weight through hypnosis you really need to be hypnotized by someone else and not yourself and there's not guarantee that it is or isn't gonna work.
Sometimes the hypnosis can be more effective for weight loss than exercise and other diets but for some people they need to get exercise and change their diet or do intermittent fasting to lose weight.
Around 10 percent of the world population can be hypnotized and not everyone is a willing subject.
To be able to be hypnotized you must be a willing subject and want to be hypnotized.
If someone just randomly tried to hypnotize someone it would not work because that person is not willing at the time to be hypnotized.
Everyone's brain is wired differently and some peoples brains allow them to be hypnotized while others do not allow them to be hypnotized.
So not everyone can be hypnotized even if the person is willing to be hypnotized but willing to be hypnotized makes it easier for the person to enter hypnosis.
