Here’s what Jimmy and Adam talked about in Episode 17:

– Can you eat too much fat on a ketogenic diet?
Hello Jimmy and Doc Muscles,

Thank you so much for the great podcast you have put together. I love the focus on the keto way of life. I listen to all of your other podcasts, Jimmy, and this one is my favorite.

So here is my question… I have heard it hypothesized that you can overeat fat on a keto diet. The theory I have heard is before you can burn your fat stores, you have to burn through the dietary fat you have eaten. Is this for real? I’m trying to understand more about exercise and its effects on ketones. When I go for a good long walk, if my ketones go down, is it because they are being utilized more? I’d like to think that I’m really working on burning the stored fat when I go for a walk versus just the dietary fat I have eaten that day but I’m not sure that is the case.

I also conducted my own N=1 experiment on my blood glucose. I used to come home from work and go for a walk, then come back and have my dinner. I would start out before dinner with a blood glucose of 96-104 then do the post-prandial after and it would go up to about 110-114 before coming down again. Then I decided to eat dinner as soon as I got home and go for a walk immediately after. My blood glucose before dinner was 101. Then I went for a 45 minute walk immediately after dinner and tested again at the one hour mark and it was at 96! Do either one of you have any thoughts about the timing of exercise when it relates to eating and its effects on glucose and ketones?

Thank you so much for the great work both of you do!

– Do higher ketone levels mean more fat burning than lower ketone levels?

– Does eating ketogenic spike cortisol levels?
I’ve noticed that when I do a strict ketogenic diet and extended fasting, my cortisol shoots through the roof. I have interrupted sleep, wake up at 4:30 or 5:00 am and can’t go back to sleep (which was great at first to get things done! But now is just annoying). I’m wired but jittery, irritable and edgy. I want the benefits of the higher ketones, but without the negatives of high cortisol.  Most of what I’ve read suggests to increase carbs to bring cortisol down. What can I do?
Thanks!
Amberley

– Will eating low-carb keto reduce my testosterone levels?
Hey Jimmy,

I want to say that you have made a huge difference in my life. I switched to keto after listening to your podcasts and reading your book. I have dropped 30 pounds in the first month, and have never felt better. Thanks for all the great info you put out there for us. I do have a question though, I have heard that carbs are necessary for testosterone production. I’m 32 this year and want to make sure that a keto diet won’t have any deleterious effects on it. Do you have any thoughts on this?

Thanks for your time,
Justin

Plus, don’t miss our featured listener question from this week’s featured Keto Talk Mailbox e-mail at the end of the show:

Hi Jimmy,

Thank you so much for all the hard-to-find information you’re putting out there for the rest of us.  You’re a great resource!  I love all of your podcasts, especially Keto Talk with Jimmy Moore and the Doc.

I am hoping that you will have time and ability to help me get a question answered.  I have been searching all over the net to find some information about whether a LCHF diet should affect liver function tests, and I can’t really find what I’m looking for.  I figured that since you seem to be the king of keto blood test results, you would be just the man to answer my question:

I have been eating LCHF for about a year and a half (and thanks to Dr. Nally’s protein calculator, I’m recently down to 50g protein and under 20 carbs – usually way under – leaving about 85-90% fat).  I am not over-weight, but when I started LCHF had been at the top of the normal range for myself and just heavier than I was comfortable with.  I have recently been having some digestive issues, so had some blood tests including a liver panel.  One of the liver measures (ALT, I think, but it could have been AST – the enzymes) came back slightly elevated, so my doc has ordered an upper abdominal ultrasound.  I am scared to death that my doc is going to say that I need to change my diet, but I really want to stay keto (even though I really haven’t seen the same level of benefits my husband has, I still think it’s so good for me). 
So here’s the question:

I know that some blood tests look different for those on LCHF (such as cholesterol) and that it’s not necessarily a bad thing. Is there any reason to think that elevated liver enzymes is normal for someone on LCHF and not a bad thing?  Or might LCHF cause elevated liver enzymes and actually indicated faulty liver function?  Or are these things completely unrelated.

Thanks for your help!  I have so many keto questions (for someone who is not overweight – which I think is different than the typical situation), but I decided to pick the most pressing one, so I will continue to listen to your podcasts and continue to learn and hopefully get my other questions answered!

Keep up the great work.

Joanne

  • Please help. I cant listen to the podcast and all these questions are very relevant to me. I was banting last year and lost 17kgs for the year. I have been following keto now since Jan but have not lost a gram. Could this be my menopause??
