Planning to start eating healthy? Here s a new book to help you do so. Healthy Kitchen authored by celeb nutritionist and fitness trainer Marika Johansson is out on stands. The book was unveiled last week by Sidharth Malhotra who himself follows her advice. Marika changed my diet for my role in Brothers . She taught me the importance of refuelling the body to help it recover from the hard and intense martial arts and weightlifting workouts. I gained 10-12 pounds by eating healthy and protein-filled diet food five times a day. Each meal was well-balanced and tasty said Sidharth.
