I'm impressed with the results I'm seeing already! It's only been 5 days so far but I can see it. My int fast window is 8x16 so I only eat from 6am to 2pm. I haven't stuck with the menu exactly but I stuck to the window... Except for today.
Other than that I am glad to see my body coming back to life! My back pain is going away slowly as I keep up with the mobility movements.
