To work with Dr. Laurie Marbas, visit: https://www.drmarbas.com/ Leif Arnesen's journey from meat-eater to plant-based eater is an inspiring one. He began lifting weights in college and was diagnosed with cancer at the age of 21. After undergoing surgery to remove the cancer, Leif became obsessed with learning about health and nutrition. He discovered the China Study, which convinced him that going vegan was the right choice. Today, he has coached over 1000 vegan athletes! Leif's Instagram: https://www.instagram.com/thevegangym/
