In this moment Dr Tim Spector unravels the myth of calorie counting for health and weight loss. Dr Spector discusses how dieting is not just a simple case of tracking calories in compared to calories, as it is nearly impossible for even professionals to accurately count calories. Furthermore, just as people and their lifestyles are not the same, neither are calories. Calories from either quality whole food or ultra-processed can have radically different impacts on your health. Instead of obsessing about calories Dr Spector believes you need to be focused on the quality of your food.
