Hi,
I was away for 4 days( out of country) and forgot all my food back home...I came back Monday and following the plan again. I am guilty of eating and drinking and not being watchfull when I was away...my question is how long will it take for my body to come back into the burnout mode again...

Between 2 to 4 days. Same for when you started the program. You refilled your carb tanks so you have to burn them down. For some it is faster but for most it falls in to the 2-4 days.

Thanks @redhead14
It can not be accelerated...

Nope...just prevented...
