Sadly everyone wants to see outward changes of this diet, and it barely works that way. There are physical health symptoms that appear through poor diet, but most people can't even see those change once the diet is replaced. How can you see a physical representation of a chemical change? Diet changes your body's chemistry. Other things like exercise change another thing. Yes, they will overlap sometimes. However even looking at pictures of me from years ago you could never tell that in all of them I just wanted to sleep. I felt so sick and tired! Weak. Now however, anything comes up in my day and I just think "sure, let's do it!"
I think it would benefit us more to move away from the concept of seeing the changes induced by raw, and rather tout our medical experiences. I have the physical documentation to prove I was on Adderall. DaBoss has medical records for his medication. GS has proof of eczema. The list goes on. Things like that add credibility. Then the only step after that is using that credibility to share the facts on bacteria, enzymes, complete amino profiles, vitamin bioavailability, and all the other benefits of eating raw foods.
