if you slip up how long does it take to get back to normal?
Ketogenic Diet
If you have been on the Ketogenic Diet for a while and are Keto Adapted, it doesn't take you long to get back on track; as Luke and Shawn noted.
I have been on the Ketogenic Diet for over 4 years. I got off of it twice for a few days the first year. I had no problem quickly getting back on it.
For the last three years, I have maintained the Ketogenic Diet.
The reason that I am on the Ketogenic Diet is that I have a metabolic condition.
Carnivore Diet
This, as you know, it a high protein and fairly high fat diet. You may be able to achieve ketosis at times.
However, since this is high protein diet you end up converting protein into glucose (gluconeogenesis).
With that said, I know some people who have done well with it.
Restrictive Diets
Restrictive diets of this nature are hard for the most people to maintain.
The same is true of everything. The harder you make it the less likely someone it to maintain or stick with it.
New Years Diet Resolutions
This is one of the dumbest thing there is.
For some reason, one day out of the year, people feel the need to make changes in their lives and end up failing.
"On average, 80% of New Year's resolutions fail by the second week of February. "

As I have posted on this site, a different training protocol needs to be followed when on the Ketogenic Diet.
I am now at home and like the Keto Diet. However, ...
I Do Not Recommend It
This goes back to the fact that the harder you make something for some, the more likely they are not to maintain it or stick with it.
As someone once said, "People who succeed are willing to do what other won't."
An Alternative
A diet that provide some of the same benefits as the Ketogenic Diet and requires less effort is Intermittent Fasting.
Nothing to count, prepare or count. You just skip a meal ever once in a while.
What Your Interesting?
With in mind, why are you considering these two diets? What is your objective and what are you willing to do to make it work?
The fact that you are regular on this site and train is a good indication that you have the drive make thing work.
