My Secret Life: Pierre Dukan, 70, diet guru

'I injected my friends and family'

My parents were... My mother was somebody exceptional – and my father was very, very severe. I loved it because he gave me the law and she gave me the emotions. Like a plant: I had enough water and enough light.

The household I grew up in... From my window I had the sea and every night I heard the noise of the small waves. Every morning I saw the sparkle of the sun and I think it is something that helped me a lot. In this house, [I lived with] my mother, father and two brothers.

When I was a child I wanted to be... Around 10 years old, I had a panic [when I had] an injection. My mother wanted to help me, so she taught me to make [a pretend] injection, and from then, I became a small doctor, I had a small bag, and learnt to make injections on my friends and family so I wasn't scared. That's when I started to think about medicine.

If I could change one thing about myself... My age.

You wouldn't know it but I am very good at... I am very manual – somebody who can do everything with their hands. I can repair many things in the house.

You may not know it but I'm no good at... seeing the people you love dying.

At night I dream of... Most of the time, I am running [away from] someone who wants me to suffer. I run and run, but it takes me a long time to escape them.

I wish I had never worn... Certainly school uniform I disliked a lot – I hated to wear it when I was very young.

What I see when I look in the mirror... A friend.

My favourite item of clothing... A pullover in Scottish lamb's wool.

I drive... I have no car – I go on the Metro or by taxi. But the last one I had was a Porsche! It was a long, long time ago.

My favourite work of art... I make sculpture: I find in the street, or on the beach, pieces of metal and wood, and I arrange them. I do it with my children – we always come back with some pieces because they know how much I enjoy it.

My favourite building... Le Tour Eiffel. I live near the Eiffel Tower and I love it, especially at night, with the lights.

Movie heaven... Gone With the Wind. It's my preferred English – I mean American! – film.

My greatest regret... Not to have had two lives to lead.

My real-life villain... Adolf Hitler.

My secret crush... Audrey Hepburn.

My five-year plan... I would just like to still be here on Earth.

My life in six words... Fight against obesity, over the world.
