We run one day weight management courses based on Steve McNulty's book "Simple Secrets to easy Weight Loss".
This is a no diet, no deprivation, no supplements, no pain, no surgery, no sweating, no nothing other that enjoying food when you are hungry.
Steve's system helps you identify the anxiety triggers that make you develop food cravings. Once identified Steve's system teaches you how to eliminate these cravings easily and quickly - putting you in control of the food.
