Dr Diane Cooper is a clinical exercise physiologist with a PhD in health and weight loss. I have been practicing as a consultant and researcher in this area for the past 10 years. I have analysed the effectiveness of all of the different types of diet and exercise interventions that have been used over the past few decades. I have worked with hundreds of people in my healthy living clinic over the last 10 years, and I know what works long term and what absolutely does not work. I have combined everything I have learned from research and practice to create the ultimate simple but effective weight loss programme called True Transformation.
