While calories certainly are one piece, there is much more to the puzzle of weight management and metabolic health, like hormonal cascades and oxidative stress. My guest today is Dr. Robert Lustig, an author and neuroendocrinologist with expertise in metabolism, obesity, and nutrition. He has dedicated his retirement from clinical medicine to help fix the food supply in any way he can, to reduce human suffering, and to promote a collective vision of metabolic health: protect the liver, feed the gut, support the brain.  In this episode we discuss: Is a calorie really just a calorie?
