Tell me more....
I'm new to PB eating (on my 2nd week). While scanning the forums, I've come across several posts that briefly touch on the body's transition from carb burning to fat burning. I was hoping someone could tell me a little more about this process??? Is this part of the waxing / waning energy level that I'm feeling... what's the physiology behind the process... how long does the transition typically take...?
I've google searched it, but mostly come up with websites that are selling something, rather than explaining it.
thanks for your time.
