Highly recommended!

I was surprised at how good the food was! The five days took effort, but it wasn't an extreme challenge; definitely doable! I was sluggish the first two days, but after that, I felt fine. I definitely plan on doing this every year.

Quite manageable; felt great

As a breast cancer survivor I want to do everything in my power to prevent a reoccurence; if that means doing a 5 day fast mimicking diet - I'm in. My husband joined me for moral support and both of us were surprised at our energy level; clear headedness and minimal cravings. I'll be doing this again - a few times a year - to continue supporting my proactive approach to reducing reoccurence rates.

Good experience

Dr Funk recommended it, and I was able to complete the full 5 days. It was successful.
