The owner of my gym told me today that a study has come out about long term keto metabolic adaptations. He said after some time on keto your body will stop metabolizing as it did on keto leading to stalls and weight gain. He said from an evolutionary standpoint it makes sense, because during part of the year you’d encounter more fruits, etc, whereas in other parts it would be less growing things and more meats, etc. So, he said it would be better to cycle to make sure your body is adaptable to both ie able to handle carbs well. Any thoughts?

Ask the owner for the title of the paper or the url. Let’s see the science.
This community is pretty up on the science studies regarding our WOE. I have a hard time believing if such a study had reciently been released that we wouldnt have heard about it here.
Im with Eric. I’d ask where I could find that study. I’d just say “that’s really interesting. I’d like to read more. Where can I find it?”
My hypothesis is if we have daily and monthly metabolic cycles (sleeping and menstruation) we might have an annual metabolic cycle that requires a summertime carb-up of peaches and strawberries.
Of course he’s right. It took me over four years to figure this out, and I’ve been eating carbs for metabolic purposes ever since.
Lipolysis and lipogenesis are both adaptive processes. There are detrimental effects at the extremes of both. When it comes to hormones, working in antagonistic pairs, the ideal State is balance, the ability to consume both fats and carbs with equal efficiency.
Swinging from one detrimental extreme to the other can take quite a bit of time. So, it’s kind’a absurd for noobs to have strong opinions on this due to lack of experience. Once detrimental lipogenic adaptations are dealt with, wait four or five years of practicing Nutty Keto to see what happens. You’ll see what I mean.
To determine the effects of a 24-week ketogenic diet (consisting of 30 g carbohydrate, 1 g/kg body weight protein, 20% saturated fat, and 80% polyunsaturated and monounsaturated fat) in obese patients.
Polyunsaturated fatty acids (PUFA), omega 3 and omega 6 fatty acids are both essential and our body needs them but I agree that the 80% reference seems a little out there.
I somehow doubt he’s experienced it himself. So it would be a debate of theory vs. actual experience. To me, Phinney is a Noob. I also suspect he’s never been obese.
Description please. Not sure what you mean by this?
While this might be true (or not), I believe his experience with others who have would qualify to the validity of his position opposing a theory of a personal singular experience.
Dr. STEPHEN PHINNEY a physician scientist who has spent 35 years studying diet, exercise, fatty acids, and inflammation. He has held academic positions at the Universities of Vermont, Minnesota, and California at Davis; and leadership positions at Monsanto, Galileo Laboratories, and Efficas. He received his MD from Stanford University, PhD in Nutritional Biochemistry from MIT, and did post-doctoral research at Harvard.
He has designed, completed, and published data from more than 20 clinical protocols involving foods, diets, exercise, oxidative stress, and inflammation. His recent work in the private sector has resulted in several issued and pending patents. He has authored more than 70 peer-reviewed papers and book chapters on a wide variety of topics, including the effects of diets and specific nutrients on inflammation, the interaction between diet and exercise and their effects on obesity, body composition, physical performance, and cellular membrane structure.
Dr. Phinney’s clinical experience includes 20 years of inpatient and outpatient clinical nutrition, including directing multidisciplinary weight management programs in 3 locations. As an internationally recognized expert in obesity, carbohydrate-restricted diets, diet and performance, and essential fatty acid metabolism, he has given hundreds of presentations to industry, health care professional, and lay audiences.
In collaboration with Dr. Eric Westman and Dr. Jeff Volek, he co-authored the New York Times Best Selling “The New Atkins for a New You” published in March 2010.

Ancel Keys also had an extensive resume. Now, I’m not comparing the two, because basically I agree with Phinney. I just have a different view of the long term effects of a keto/lipolytic eating pattern. specifically, overall Lipolysis vs. focus on Ketosis. Particularly the limited role of carbohydrates on metabolic balance within the context of Maintenance. As a result, I am the “Nutty Keto Heretic” as I do believe that limited and periodic intake of carbs are beneficial in the metabolic sense. This was/is a part of Human Evolution, and IMO is not easily disputed. I’ll reiterate, that metabolic responses to nutritional patterns are adaptive processes, with specific individual responses often subject to genetics, and are therefore fairly subjective when applied to overall populations. Some may do well following one pattern, some may not.
One thing I’d like to point out is that with virtually all the people I’ve advised as far as fat loss have reintroduced limited carbs into their nutritional patterns, when and how much determined by degree of derangement and genetics, and all who’ve stuck to the process have been successful. Without fasting, and without significant stalls.
Since I’ve not read all his work, I may be in error with my views, we may share some of the same views in regard to Maintenance. I was influenced by John Berardi many years ago, and consequently tend to look at things hormonally, with a focus on balance, and the negative effects of nutritionally induced imbalances.

Fair enough. Views are definitely an individual thing and our right to have them should be respected. It is also good that we recognize that they are opinion and susceptible to error. I will not challenge yours on this issue as I view this topic as in it’s infancy and needs to be studied more. I also agree that metabolic derangement play a big factor and should always be considered in the equation. Evolution or damage control?
