If you are interested in the low-carb, moderate protein, high-fat, ketogenic diet, then this is the podcast for you. We zero in exclusively on all the questions people have about how being in a state of nutritional ketosis and the effects it has on your health. There are a lot of myths about keto floating around out there and our two amazing cohosts are shooting them down one at a time. Keto Talk is cohosted by 10-year veteran health podcaster and international bestselling author Jimmy Moore from “Livin’ La Vida Low-Carb” and Arizona osteopath and certified bariatric physician Dr. Adam Nally from “Doc Muscles” who thoroughly share from their wealth of experience on the ketogenic lifestyle each and every Thursday. We love hearing from our fabulous Ketonian listeners with new questions–send an email to Jimmy at email@example.com. And if you’re not already subscribed to the podcast on iTunes and listened to the past episodes, then you can do that and leave a review HERE. Listen in today as Jimmy and Adam answer your questions on the low-carb, high-fat, ketogenic lifestyle in Episode 72.

Here’s what Jimmy and Adam talked about in Episode 72:
- Keto Talk super fan Jacki wrote us a song
- Coconut oil isn't healthy. It's never been healthy.
- Is eating carbs a good way to lower blood sugar? And which is more important as a health goal—lowering blood glucose levels or insulin levels?
I understand that blood glucose can rise on a ketogenic diet due to the physiologic glucose sparing effect you guys have discussed several times on the podcast. In his new book FAT FOR FUEL, Dr. Joe Mercola shares his solution to this by simply eating more carbs and thus trigger an insulin response to bring the glucose down. Of course, if you eat more carbohydrates in your diet to make this happen, it will invariably kick you out of ketosis. So in light of this, it begs the question: which is worse for you to have—higher glucose levels or higher insulin levels? Is there another way to bring blood glucose down without triggering insulin to go up? Maybe some light exercise would do the trick? Thanks for answering my question.
1. In light of my blood work results, is it possible keto isn’t right for me? If I want longevity, energy, and mental benefits, how should I eat?
Hi Jimmy and Adam,
Thank you for all that you're putting out there regarding ketogenic living. I first came across you Jimmy when you did a podcast with Dave Asprey a few years back and have listened to all of your Livin’ La Vida Low Carb Show and Keto Talk episodes ever since.
I've been experimenting with keto on and off for the past few years. I don't do it for weight loss since I'm a lean 32 year old male at 8% body fat with high muscle mass and in very good shape (I can run a sub-6 minute mile, deadlift 3x my body weight, etc.). I follow keto for constant energy, mental acuity and longevity purposes.
When measuring my blood glucose levels while in keto, I find that they're quite high: 100-120 fasting blood glucose and up to 140 postprandial. I'm aware of physiologic insulin resistance, but the numbers nonetheless concern me; I just had blood labs done and my HbA1c was 5.8, up from 5.2 which were my numbers a year ago while on a moderate carb diet.
My triglycerides have also gone up from 54 in February on moderate carb to 97 today. My total cholesterol has risen from 180 to 225 but that's to be expected on keto. My testosterone is a bit on the low side for my age at 450, but it’s been this way regardless of whether I'm on keto, moderate carb, or have taken a week off of training (I was hoping keto would raise it).
Dr. Dominic D'Agostino acknowledges that for certain people, keto simply isn't the answer. Although I feel healthy eating this way, my blood work results seem to indicate otherwise. Am I one of those people who flourishes on moderate carb eating and the occasional fast and keto just isn't for someone like me? It's worth noting that my mother who is in her mid-60's is in spectacular shape with great lab numbers without ever going to the gym and she has always eaten a carb-laden diet.
One more interesting note to share with you is my body composition is identical whether I’m eating keto or high carb. So, with longevity being one of my top priorities alongside stable energy and mental acuity, what nutritional approach do you think I should do to reach my goals?
Thanks a lot for your help!
2. Is it possible to create acidosis from your diet and exercise choices? How can you prevent this from happening?
Thank you for your work as it's an absolute asset to so many of us. I started doing 2 workouts a day of weight lifting and running or walking. I’ve noticed I started having painful urination as well as my side started hurting recently. When I checked my urine ketone levels several times, they were always extremely dark. After reading a graph on Dr. Andreas Eenfeldt’s website about acidosis, I became concerned. I immediately ate a bunch of carbs from ice cream and other sources to try to deal with this issue and stop the pain by driving down the ketones. I also drank some baking soda mixed with water since I thought this had to do with acidity. Amazingly, 8 hours after doing this I STILL showed ketones on the urine ketone sticks. So then I ate some chili cheese fries bringing my total carb consumption that day to 500g.
It's now been 3 days later and my body had never stopped producing ketones. It went to small levels at one point when I skipped my workout for a day. I'm a type 2 diabetic with chronic kidney disease who's used straight keto for about a year and have never seen anything like this. If I have a carb-filled meal, this will usually kick me out of ketosis for 4-5 days. So, have you seen acidosis happen as a result of diet and exercise? What are some things I can do to prevent that from happening again?
Thanks for your insights on this!

3. Is there any added benefit to taking one month off from keto annually vs. constantly staying in nutritional ketosis?
Hey Jimmy and The Doc,
I have listened to most of your Keto Talk podcasts as well as some LLVLC podcasts and they are both informative and entertaining. What I take from hearing people like Dr. Eric Westman, Dr. Ted Naiman and Dr. Nally is that the hormone insulin is what controls and signals the storage or burning of fat and that lower insulin levels (outside of being a Type 1 diabetic) is healthier. It seems that intermittent fasting, keto, and exercise all lower insulin and improve health. Many of the arguments point to the evolution and hunter gatherer hypothesis of storing fat in times of plenty during the spring and summer and then burning stored body fat during the winter and when food was in shortage between animal kills. The problem with the modern-day SAD diet is that there are too many carbs in our diet that leads to elevated insulin levels which then results in insulin resistance and your body is constantly storing fat, never using it in times of need which never come, and leaves the individual perpetually hungry to eat and eat and eat.
My question for you guys is this: if we are designed to store and burn fat and alternate from using ketones and glucose as our fuel source, then isn’t this an argument for cycling in and out of ketosis on a regular basis? Since getting keto-adapted takes about 4-6 weeks for most people, why wouldn’t doing 11 months of keto with one month of a non-ketogenic diet be better than eating keto 24/7/365? I have not found any studies on this and I would imagine the change in diet would be good for the body to serve as reset for just one month a year. I know yo-yo dieting is bad for your overall health and that there is a risk of a relapse to your old ways when you get off of keto that could prevent you from going back to it again. But there might be real benefits to this as it probably better resembles how our ancestors evolved in their nutrition and may help reset your body to get better results after long-term ketosis. What do you think?
