View Full Version : CKD question

While you are on this diet, your brain takes 1-2 weeks to shift from glucose to ketones for fuel right? If so, wouldn't the week carb up reset the brain's metabolism back to glucose?

I think the carb up is 2 days not a week.

Sorry, I meant weekly.

I think that is one of the main reasons for the carb up. Your brain functions a lot better with glucose than ketones.
The carb ups are meant to help gym performance, but I also find that it helps me to get back to a normal mind state. I was in Ketosis for 3 weeks straight and felt like I wasn't really there. I did my carb up and felt 100% better. It also helped to get the fat burning process going full steam again.

This post is very timely.
Doing a CKD (5days/2days carb) and I felt like CRAP on my first carb up day. I felt better and more clear minded on my ketosis days than I did yesterday. Go figure. I decided to go light on my carbs for the second day (today) really using only half the day to "carb up". My training is still pretty decent early in the week - of course, little to no energy towards the end of the 5 days, but I make the most of what I can do.
Just curious - if anyone else has this type of negative insulin response to a carb up though....?

Do you mean you felt like crap as in really tired and lethargic?
if so, it's from the seritonnin boost you get from a meal high in carbs.

Tired and lethargic is an understatement! I guess I don't like seritonnin as much as I thought.

When you're doing CKD, do you keep on your regular workout schedule and add in 2 depletion workouts or do you just do depletion workouts?
