How well hypnosis works to help people stop smoking depends on who you ask. Study results have been mixed. In 2010, a systematic review of published studies found that there wasn't enough evidence to support the use of hypnosis. Another review published in 2012 said that studies do support a possible benefit from the use of hypnosis. In discussing alternative methods for quitting smoking on its web site, the American Cancer Society says that while controlled studies have not supported the effectiveness of hypnosis, there is anecdotal evidence that some people have been helped.
Weight loss occurs when the body is expending more energy in work and metabolism than it is absorbing from food or other nutrients. It will then use stored reserves from fat or muscle, gradually leading to weight loss. For athletes seeking to improve performance or to meet required weight classification for participation in a sport, it is not uncommon to seek additional weight loss even if they are already at their ideal body weight. Others may be driven to lose weight to achieve an appearance they consider more attractive. However, being underweight is associated with health risks such as difficulty fighting off infection, osteoporosis, decreased muscle strength, trouble regulating body temperature and even increased risk of death.
Although there are different techniques, clinical hypnotherapy is generally performed in a calm, therapeutic environment. The therapist will guide you into a relaxed, focused state and ask you to think about experiences and situations in positive ways that can help you change the way you think and behave. Unlike some dramatic portrayals of hypnosis in movies, books, or on stage, you will not be unconscious, asleep, or in any way out of control of yourself. You will hear the therapist’s suggestions, but it is up to you to decide whether or not to act on them.
