In this companion episode we had the pleasure of talking with metabolism expert Dr. Lynis Dohm about his manuscript that we discussed in the last episode and his Vicious Cori Cycle hypothesis. In this episode we talk a lot about the ability of lactate to provide insight into metabolic health. Lactate, the seemingly inauspicious metabolite wrought with misleading narratives including those that implicate it as a cause of muscle fatigue with exercise, has never been so exciting!
