Ketogenic Diets

Is there any fast food out there that is worth a damn? And what about Ketogenic Diets? Are they really good for performance and health?

KETOGENIC DIETS#1
While I do not advocate the consuming of fast food…I do have one weakness…In-N-Out Burger.

Double Double with Onions Protein Style is my order of choice when we looking for a quick meal. For those of you that are not from California and are not familiar with In-N-Out Burger, it is a local burger chain that emphasizes fresh ingredients and made to order burgers. It places high on the list for everyone I know and it rocks!

As for Ketogenic Diets, here is exert from study that was done in 1930 on ketogenic diets. Two individuals were followed for 1 year while they ate a prolonged diet of meat and fat. The study is called PROLONGED MEAT DIETS WITH A STUDY OF KIDNEY FUNCTION AND KETOSIS BY WALTER S. MCCLELLAN AND EUGENE F. Du BOIS.

“Two normal men volunteered to live solely on meat for one year, which gave us an unusual opportunity of studying the effects of this diet. The term “meat,” as used by us, included both the lean and the fat portions of animals. The subjects derived most of their calories from fat and the diet was quite different from what one, who uses the term “meat” as including chiefly lean muscle, would expect. Rubner (1) called attention to the fact that a man cannot live on meat alone because physical limitation of the apparatus of mastication. He was evidently considering only lean meat as fat offers little difficulty…”

 

“Both men were in good physical condition at the end of the observation. There were no subjective or objective evidences of any loss of physical or mental vigor. The teeth showed no deterioration and gingivitis had disappeared. There was, however, an increase in the deposit of tartar on teeth of V. S. Bowel elimination was undisturbed-V. S. required no extra catharsis and K. A. was regular throughout.”

 

At the end of the year, the subjects were mentally alert, physically active, and showed no specific physical changes in an system of the body…Vitamin deficiencies did not appear…In these trained subjects, the clinical observations and laboratory studies gave no evidence that any ill effects had occurred from the prolonged use of the exclusive meat diet”

 

It seems we have known the benefits of ketogenic diet for many years. I always suspected those pesky carbs were just a lot of hype.

    I read somewhere that a ketogenic diet is not appropriate for all forms of physical activity, especially prolonged endurance. The article used Inuit as an example, although they didn’t test them physically…only made assumptions about that.

    So, I guess my question is…SHOULD we or simply CAN we live on a ketogenic diet? The abstract here only touches on the latter (CAN). I think Robb Wolf has articles related to performance, which I’ll look at later, but a follow-up question would be…Should we resort to a ketogenic diet for CFFB (impact on social life aside)? Is it appropriate for both GPP and athletic endeavors? What about fruit, roots, and the associated vitamins and minerals that we can’t live without?

    A more broad question…What is the trade off between longevity and performance? There are so many sciences that show, both empirically and theoretically, that an entity has a finite work capacity, which is a product of some measure of time (longevity) and power (performance) and is independent of maintenance/repair and possible renewable energy source. That said, eventually, the body will burn out from accumulated exposure, assumedly, in this case, from wear and tear unrelated to environment. So, where do certain lifestyles/diets, i.e. ketogenic, lie on the continuum of longevity versus performance and which would produce the greatest overall work capacity (if so desired)?

    I find all of this very interesting. But to Clinton, I am no nutritionist or huge history buff. However, from what I have learned and come to understand about zoning, and paleo, and also the ketogenic diet is that it all depends on what works for you. For example those looking to compete seriously in “endured” sports the ketogenic may not be as good, as it could work ideally for someone looking to focus on strength gains and lean muscle mass. I would seriously take into consideration your ethnicity and origin of your race, think back and research what they would have lived on in their particular area of origin. For me personally converting into becomming quite the crossfit athlete, zoning seems to best fit my needs. So I would think a lot depends on where you would like to go athletically and how you can properly fuel to get you there, but definitely not a simple black and white subject on if we should or shouldn’t ketogenic.

    I have yet to read this study. It couldn’t have come at a better time. I just recently cut carbs on a paleo+dairy diet and have been in ketosis for about 2 weeks. The more information the better. Me and my brother started cutting carbs at the same time. However, he has quit due to performance issues and I’m still making squat and deadlift PRs.

    There is a great article on Panu.com that basically explains how the human body’s optimal source of energy is fat- hence body fat. It goes on to say that when a person has been in ketosis, and becomes adjusted to burning fat for energy, adding carbs pre-workout is like adding NOS to a car. Personally, I have been vlc paleo for about 6 months while hitting pr’s consistently in strength and metcon, as well as cutting bf % to very low levels. Most carbs are from berries, and leafy greens with some starchy carb like bananas post w.o.d

    I love conclusions that are based on a sample size of n=2.

  8. Bobby – Me too. Got to love studies done 80 years ago on 2 people. I included the study b/c I was blown away by some of the detail. Like the descriptions of their stools and observations. And the fact is was done 80 years ago before a lot of “what we know” could get in the way. No bias…just simple information.

    I don’t know…as far as bias, it was sponsored by a grant from the Institute of American Meat Packers. How non-biased is that?

    I’m not saying I disagree, but it makes me a bit suspect.

    Well here’s the biggest and probably one of the most important questions concern Keto:
    What about ketoacidosis? I know they said their were no K.S or V.A. problems, which I am assuming elevated ketoacidosis affects this. Has anyone done further research into to this and the effects?
    After several years of battling with my diets I started with the whole paleo thing and the weight is coming off. I’ve had to charge up my thyroid again, I wasn’t eating enough and had a crashed metabolism. I currently in a calorie reduction to drop the fat with a 40/30/30 diet (40% protein) and the fat is coming off with ease. I know at some point I’ll have to change this up once I get to a plateau but wanted to know more about the effects of long term keto. I’ve found higher energy levels when I’ve done keto but the one day carb up initially gave me a charge in energy I always ended up with a crash at the end of the day; but I always scheduled my carb day on an off day.
    When Ketoing is it OK to have a PWO drink mixed with fast and slow carbs or should they be avoided all together?

    • Not be an a-hole but, you need to do one of two things. Either put your computer away or start using it with intelligent search terms.

      Ketosis is not ketoacidosis. Two very different things. And a ketogenic diet does not cause ketoacidosis.

      “Diabetic ketoacidosis results from dehydration during a state of relative insulin deficiency, associated with high blood levels of sugar level and organic acids called ketones. Diabetic ketoacidosis is associated with significant disturbances of the body’s chemistry, which resolve with proper therapy.”

      “Diabetic ketoacidosis usually occurs in people with type 1 (juvenile) diabetes mellitus, but diabetic ketoacidosis can develop in any person with diabetes. Since type 1 diabetes typically starts before age 25 years, diabetic ketoacidosis is most common in this age group, but it may occur at any age. Males and females are equally affected.”

      And here is the problem with diets…they are un-sustainable. How about a life style change. Start eating real foods, get some exercise and stop wasting my time and yours with stupid shit.
