Tom admitted it was hard to lose weight to star in Stuart: A Life Backwards when he spoke to IndieLondon: Absolutely. But Stuart: A Life Backwards was a brilliant part that an actor like me would totally want to do. So, you just do it. It’s much less daunting once you’ve put your foot on the road to it. I’m a notorious couch potato and I don’t like exercise. Half an hour of physical exercise, like jogging or fast walking a day is a start. Then there’s your diet. You cut out sugars, fat, soy sauces… anything that’s nice. Tea and coffee is replaced by boiling water with lemon. It’s amazing how quickly you get into it. There’s also herbal tea and a lot of water, obviously… about two litres a day… It’s about motivation and it has to be something that’s realistic for you to keep up."
