Body IO® FM #18 | Q & A No. 2

Listen on iTunes.


Should you use Carb Nite during pregnancy? Does one type of training work for everyone? Sport training camps, how do I eat when practicing and competing multiple times a day?
In the second episode of this series of Q&A podcasts on Body IO FM, Kiefer and Dr. Rocky take the questions you’ve asked on Facebook and answer them.

  • Great work again guys. I think from pictures alone it is clear to see Jon Andersen is some kind of genetic freak! Dialling back the protein was one of the biggest reset buttons I ever pushed in my own diet.

  • For next Q&A,

    In a previous podcast you talked about you recommend a multi-vitamin for people and how that’s never a bad idea. How would you respond to recent research (sorry can’t find cites) arguing that multi-vitamins are at best non-effective and possibly even harmful in very high doses? Does that fit with your idea that once you process something and then put it back together the bioavailability is already screwed up so it’s not going to have the same effect as whole foods or possibly even have an opposite effect (I can think of one epidemiological study showing how folic acid supplementation is related to an increased risk for prostate cancer).


  • Hello,

    I’m not sure if this is the right place to post my question for a future Q&A but here goes. I have anorexia and orthorexia which I’m trying to recover from. I have been following a very low carb diet for at least 1.5 years not doing any refeeds or having any treats/junk at all. I’m feeling lethargic both mentally and physically and I have most of the symptoms of adrenal fatigue. My question is basically how I can use Carb Nite or CBL to recover? Should I simply put in some carb nites with cinnamon rolls (I would so badly like to have one after not eating one for several years), cherry turnovers etc. or should I rather go for white rice, potatoes etc. Any other advice on how I can use your protocols is also greatly appreciated!
    I’m 27 years old, 5’9” weighing 123-124lbs.

    Thanks a lot in advance!


  • In extended response to question ~ 48:00 Kiefer mentions a radical reset of sorts: 48-hr fast, rest of week extremely low carb/high fat/moderate protein (40-50g/day), minimal carb nite after, minimal carbs for several more weeks, high carb (“anything really”) for 3-4 days thereafter (“even at breakfast”). Cites subsequent body changes: leaning out, dropping body fat (possibly may not “feel good”), muscles filling up (possibly gain mass). Is this elaborated on elsewhere — situations of applicability, etc?

    ~ 53:00 re gut flora — specifically simply focusing on getting/being healthy and letting gut flora follow suit — excellent! Loved the blood pressure/medication analogy.

    Thx 🙂

  • Since we are all more insulin resistant at night time, what happens to the carbs we ingest at that time? Do our bodies react more like a person with diabetes i.e. no where for carbs to go, so they stay in the blood stream spiking blood sugar? Do they all get burned off?

    Eating or over eating carbs in the morning means they are more likely to get stored, if not used immediately. So when eating or over eating carbs at night means they wont get stored as easily but what happens to them?

    • It’s in the CBL book Trent. Kiefer also answered this in many other podcasts.

      • I’ve read CBL and Carb Nite and i am always preaching it to family and friends. I lost 37lbs in 20 weeks on Carb Nite and could still bench 300 at the end of it.

        But this is the one question i have not found the answer to… what the body does with excess carbs during more insulin resistant parts of the day.

        If they cant get into the cell they must stay in the bloodstream until burned off? I don’t know.

  • Also i understand that with resistance training the muscle cells are more likely to absorb the carbs. So to be more specific, Kiefer has mentioned in other podcasts that it is more beneficial to eat carbs at night rather than in the morning whether you have done resistance training or not.

    So in that context, i ask what happens to a healthy person if carbs are not going into cells (muscle or fat)

    I hope I’m making sense.
