·34 min·2 clips

Dr. Fung says he supports the fasting-mimicking diet because the data exist, even if he would make it cheaper and lower-carb.

The monthly Q&A opens with a reminder that fasting is a stress on the body, much like exercise. The point is to balance it rather than keep yourself under strain all the time. When the fast gets longer, around five days, Dr. Fung says a little bit of calories may be okay. He keeps coming back to natural foods, low carbohydrates, and especially avoiding refined carbohydrates. In his own reset, he says he does not eat anything for the first two days, then takes in a little food on the later days, including vegetables and some bone broth. The show also pauses for a small announcement about next month, when Patrice Mitchell will join the Q&A and the conversation will line up with the five-year anniversary of Dr. Fung's book The Cancer Code. From there, Dr. Fung answers listener questions about the fasting-mimicking diet. He says he was skeptical at first, but changed his mind after seeing the amount of research behind it, including 20-plus studies and possible benefits beyond diabetes, such as kidney disease. The episode also makes space for listeners who are new to fasting or feeling stuck, with a direct pitch toward health coaching and accountability coaching. That section is practical, not flashy. The conversation then shifts into long-term ketosis, using a carnivore example to show that years of doing this do not automatically lead to disaster. Dr. Fung says an orthopedic surgeon friend has been carnivore for about six or seven years and is doing just fine. The episode closes with the same coaching posture that runs through the rest of the conversation: keep the plan simple, stay with natural foods, and adjust when the fast gets long.

As heard by us

A practical fasting Q&A that keeps the emphasis on balance rather than purity.

This monthly Q&A with Dr. Jason Fung keeps returning to a simple idea: fasting works better when it is treated as a stress to manage, not a test of discipline to win.
