Book excerpt: Don’t Lose Your Mind, Lose Your Weight, the country’s highest-selling diet book, has revolutionized the way Indians think about food and their eating habits. Funny, easy to read and full of great advice, it argues that we should return to our traditional eating roots (yes, ghee is good for you), nutrients are more important than calories (cheese over biscuits) and, most importantly, the only way to lose weight is to keep eating. Rujuta Diwekar is one of the country’s best nutritionists, with deep roots in yoga and Ayurveda and a client list which boasts some of Bollywood’s biggest names. In the updated edition of this classic, she has added an extensive Q&A section which deals with the questions she gets asked most by her clients.
