Everyone knows you've got to burn off more calories than you consume if you want to lose weight. But for most people, it is easier said than done. Our upbringing decides our patterns of eating. If you've been brought up on a diet comprising parathas for breakfast every day, it would be hard to switch to fruit. Even if you do go on a diet and successfully curb the paratha-itch, you shall forever feel lousy and dissatisfied. Yes, our food culture has a deep impact on what we eat and how.
