Hi -- I heard that podcast too, and was intrigued. If you click Search above and type in "carb backloading" you will find a lot of posts here on the subject.

My first introduction to keto was through Kiefer's CarbNite Solution (which is keto + 1 high-carb night per week). It was relatively effective, but eating all those carbs left me bloated and craving more, so I eventually transitioned to regular keto. I've never had that much weight to lose....maybe 20lbs total. I lost 5 eating Paleo, then another 10 through CNS, but it was difficult for me. I would lose 1-2 lbs keeping carbs super low throughout the week, then re-gain almost all of it after one night of what felt like carb-binging. And I'd obviously be kicked out of ketosis and spend 2-3 days getting back in, just to be kicked out again 3 days later. For me, it set me up for some bad habits. Eventually I was fat-fasting to get back into ketosis and not eating enough calories, which left me feeling like crap.

For me, my activity level didn't necessitate carb loading. But for someone who lifts heavy and doesn't obsess over the scale, I think carb loading definitely has some benefits, especially involving leptin.

this.
I carbed up yesterday and couldn't stop eating carbs!! I don't think carb loading is for me. plus, I feel fine eating less than 20 grams per day, so I may as well just continue eating this way with out carbing up once a week.

I second this. Once I start with the carbs it takes awhile to snap out of it. Usually I need to fat fast to get back to keto as well.

When I carb up, I feel awful, and it hinders my progress. After my birthday (tomorrow), I am going to do just straight keto to see if it works better for me.

Carb backloading is not really intended for the fat burning part but for the muscle building (or keeping) part which of course will translate into burning more energy as muscle volume increase.

I went 10 days strict for ketosis (2-3%weight of carbs a day, about 10-15g) which was a "hell period" with dizzinines and gut feeling crap from all the fat, but on day 9 it felt better and on day 10 I hit my first heavy round at the gym feeling very surprised by the amount of energy withhout carbs. Had the PWO with protein stack,caffeine and 30g malto and that was it for day 10.

Day after went to the gym this time i felt low after about 40 minutes and stopped, dont want to start burning the wrong tissue ;-)
Went home had the ordinarey PWO w 30g and waited 30minutes and then binged down about 150g high GI stuff (glucose syrup rich candy and some egg-sugar-foam cakes with minimal fat, dont know the english name for them). The sugary stuff tasted awful due to the extreme sweetness (I loved candy like crazy just 10 days before so that was a strange feeling) so I struggled with getting it down, will maybe go for pure malto next time.

After 5-10 minutes the insulin had kicked in big time and I allmost fell asleep by just standing up. Had a power nap of 15-20 minutes to allow blood levels to even out and then tried to push down some additinal "crap" this time together with proteins to sustain the nights fast. This time I did not get as tired but then I did not have more than maybe 50g of high GI stuff so went to bed and fell asleep about 1-2 hours later.

Normally such a spike of insulin + fat would mean "store fat" but not in the window after working out. Though the muscle tissue will absorb the glycogen as a spunge.
At the same time the spike in insulin quickly gets your blood levels down and for the GH this is a must to start secretion (about two hours after blood glycogene levels are down the growth hormone will kick in during sleep) which is why You dont want the low GI slow absorbing and/or fiber stuff. Thus You will go to sleep loaded for building with GH spruting out during the night (depending on when You fall asleep of course) but still waking up ready to burn of the fat in the morning.

At least that is the theory behind carb backload from MY understanding but Ive only just begun so I will have to wait and see how effective it is. The 10 day "go-to-keto" period was extremely effective at least but I should probably have had the 30g high GI PWO (it does not say in the book if I should or not) to sustain growth better. Though just during that period about 1Kg of fat was cut (according to Omron Carada body measure scale) while maintaining muslce which means i am still at 20% fat but 5Kgs lighter (=4l of retended water was cut on top) and that part was very easy to spot :-D

Right now I am trying to find a good level of high GI carbs to sustain the day after work out withour excesive binging (still dont want to go too high in calories) and that will probably take a while to fine tune.
