Fantastic and inspiring. Thank you.

I’ve learned so much here. I truly enjoy Dr. Fungs videos, but there is one problem. His checkered shirts act the way in camera that it’s triggering my migraines.
– Maria76

I’ve done 18 hour (most days) and 24 hour fasts (twice a week) since watching Dr Fung and 4 months later I’m reflecting on how my body has changed but more so my work and mental clarity. I do a lot more in 7.5 hours a day now than ever before. I feel fantastic. Thank you so much for making this so simple for us to understand
– Wendy

Just a simply clear, simple, direct and terrific presentation. Thank you.

“you feel cold, you feel tired, you feel like shit”..

    Hi Bengt!

    If you are a member you can direct questions like this to Dr. Fung, in the Ask the Experts section.

    But I found this old Q & A with Fung, see below. :)

    If fasting is not beneficial for type 1 diabetics I must have misunderstood your book! I thought it would help them with cell changeover and resistance too.
    Does that not apply to us?

    A: Dr. Jason Fung: This is very complex. Fasting is about lowering insulin and insulin resistance. Type 1 diabetes starts as insulin deficiency so fasting does not help. Over time (decades) of treatment with insulin, it is possible to become insulin resistance due to the treatment. So in effect, you have both type 1 and type 2 diabetes. Here, fasting will help.
