Using hypnosis to amplify feelings of heaviness when they go into a hypnotic state can actually help a person slim down. The technique has proven to be effective for those who are extremely heavy. For someone who wants to drop just a few pounds or thirty, it is not so useful.
Andy Austin, an English NLP practitioner discovered the technique. Apparently, very heavy people do not feel the same sensations of heaviness while sitting that they feel when standing or moving around. Austin used a hypnotic induction that includes lots of suggestions of feeling relaxed and heavy, and noticed that his obese clients started slimming down just from those simple experiences and suggestions.
Although it seems contradictory that feeling heavy would help someone slim down, the psychology of it is quite interesting. People tend to eat sitting down, and having clients feel heavier while sitting in hypnosis builds a bridge to a different kind bodily awareness while the person is eating, which is a crucial time for someone who wants to slim down. The simple shift in awareness allows them to make different eating decisions.
Most of the time people are acting out of habit. For example, we do not have to think through the whole process when someone we meet the first time offers us their hand. The hand shaking routine is automated. When an automated pattern, or habit, is interrupted or altered significantly it is possible to deliberately build a new habit or pattern for that situation, or for a new, more adaptive pattern to emerge spontaneously. Which is why simply feeling heavy while sitting, a posture that is unconsciously associated with eating, can cause food choices and amounts of food eaten to change for the better.
