Then there's shame. Most people with issues around food and eating experience shame about being out of control, usually when they eat carbs or sugars (people don't overeat carrots or celery do they?). People may also feel ashamed about how much they weigh and their body. Hypnosis is a powerful ally in releasing shame and as clients tell me again and again IT IS LIFE TRANSFORMING!
In addition, words matter because the Subconscious Mind is always listening and is very literal in how it interprets information. What do you do when you lose your keys? You look for them until you find them and most likely you get a spare key in case you ever lose them again. When your Subconscious mind hears you're losing weight will want to find it again and then get you a spare! This is why I refer to shedding or releasing the weight.
"Try" is another word that doesn't work. Since he explains it so well I will let Yoda explain why.
