    The couple that fasts together, lasts together?

    My husband and I are now “fasting partners”, and time our fasts together. However, I was traveling for a recent trip lasting 5 days. Instead of developing bad habits while I was gone, my husband completed a 5 day fast. He missed the comradarie, but loved the ease of knowing exactly what he was eating. Typically he would be eating out, and not always with the best choices. Instead, he felt better and stronger when I returned!

    Review

    On day one right now, I’m really hungry. I tend to gain weight after I’ve lost the 5 pounds in the months following. I stopped eating sugar and red meat recently so hopefully that’ll help.

    Easy program

    Easy to use, tasty enough, kept me satiated throughout the week. Need more Hibiscus tea bags in the boxes!

    Really good experience

    Oddly enough, I had a really good experience. My body has gone into ketosis before so I know what it feels like. Because I had a light eating day on day zero. My body actually went into ketosis midday one. By day, two in the afternoon. I no longer felt hungry. I did not feel I needed to eat anything but still followed the program. Especially the glycerin drink that they give you. This really does help preserve muscle mass as I observed on my scale.
