This Week Abby is joined in the classroom by a Canadian nephrologist, world-leading expert on intermittent fasting and low carb, three-time best-selling author, and co-founder of the Intensive Dietary Management program, Dr. Jason Fung, MD, to help with her lesson plan on intermittent fasting.

Dr. Fung breaks down exactly what intermittent fasting is and the different benefits for your body to do intermittent fasting.
