We are on day 25 of our 30 day raw food challenge. It actually has been pretty easy. I guess mainly because we have both seen results early on. We have experienced:
no afternoon blues (sleepiness)
The weight loss for me has been nice. I have lost 10 pounds over these last 25 days. And 24 pounds over the last 3.5 months since going high raw(80%). My sister-in-law who is an avid runner claims that for every pound you lose that is 4 pounds of pressure off your knees.
We have already decided that when we are done with the 30 days we are going to stay high raw. The benefits are well worth it. And we both feel great.
