A good article on “Virtual Gastric Band” hypnotherapy here. I have clients who have had similar, if less spectacular, results. They have all enjoyed their weight loss journey and found it much easier than they thought they would. All their previous attempts have failed, but the thing that they did not realize was that they had not asked their subconscious mind to give them permission to lose weight. My weight loss clients have their subconscious minds on-side and that makes permanent weight loss possible.
