Duncan is an author, speaker and self-confessed Morris dancer. Having spent more than 20 years of his life over-doing it, he now spends his time helping people push over-indulgence out of their lives.

In our conversation Duncan confesses how strictly speaking he's drunk more than his fair share of wine and eaten more than his fair share of cake. He shares his formula for overcoming indulgence and how he has created a programme to help others do the same.

We also chat about his new book, 'Get Over Indulgence: Take control, find your stress-free life', which is a humorous, yet equally serious, depiction of his daily battles with junk food and alcohol, and how he found a way through.
