Performance Diet Types and Terminology

Yes, Mike, through a standard DNA test such as 23andme or through a physician if one wanted to better understand APOE status and risk for Alzheimer's disease. Those with an APOE 4 allele are at much greater risk, which is were most of the interest in APOE status springs from. The less than 1% of us who are 2/2 have the lowest dementia risk but evidence is emerging that we may be more vulnerable to metabolic disorders and diabetes.

Finding 2/2 participants is really difficult and there are almost no studies available with an adequate sample size to have predictive power for APOE 2 folks... you need to test over 1000 people to get 100 2/2's -- very expensive! We still need to extrapolate from genetic knock-in animal studies, mostly mouse. Thankfully findings in mice don't immediately generalize to humans as they've found a bunch of issues in mice that have the 2 allele, if they translated directly to people I'd be f***ed.

As a disclaimer, I don't endorse the diet recommendations above, but I do find them interesting. I've known for a very long time that I respond poorly to simple carbs, since my teens actually, and I've come to believe this is influenced by my apoe status. I really like fatty fish and dense, slow release, energy sources -- the older I get the more I lean this way.

Thanks Lefty. Though the 23andme doesn't specifically state which you are, you can pretty much gather which you are from their health summaries. Interesting stuff. My wife has ongoing health issues (fibromyalgia) do to genetics (from her health report I think we are pretty close to what this recommends for her - limit saturated fat - we don't do dairy at all or eggs but do a lot of nuts and olive oils which are all unsaturated). The take I got from this is she should do less cardio time wise but more HIIT work (which I've encouraged her to do anyway).

This just confirms a lot of what I thought about her diet / workouts. Cool link.

I'm in Canada and here 23andme is allowed to share APOE status results. It comes with a little button you need to click which acknowledges something about sensitive medical information etc., once you know you can't unknown and not everyone is well equipped to handle the information. I'm also still on their old site, the one with all the health reports that was developed before the FDA pulled their leash.

Interesting finding in mice...

Defo not all meat like our doc Baker (or the antithesis of a baker I would think), but strongly in favor of ketosis.

Skipping the 10 pages, of posts.
A recent exercise physiology text book on Exercise, Nutrition and Performance stated that a diet study for endurance sports from 1968 had never been refuted.

The results were easy to read. For the best endurance, a diet with 80% complex carbs, and balanced fat and protein was ideal, giving over DOUBLE the endurance of a balanced diet, or a diet with 50% fat.

The more fat in the diet, the lower the endurance. The high carb diet in comparison, was over triple the endurance. This is a regular diet, not a short term alteration. Short term boosts of a few percent are nice. But tripling your endurance is a lot better.

Hi Strider,
Welcome to the discussion!

Are you able to provide a reference to the study you are quoting? Many of us are experienced researchers -- I'd be keen to review the findings you reference.

One thing to keep in mind is that I, and others like Shawn who may still lurk here occasionally, are interested in performance diets that also support healthy aging. Dr. Shawn Baker's strategy has been to adopt an all meat diet. He must be close to a year with it if still going.

I've found some evidence indicating that the glucose metabolism of our body and brain deteriorates with age. Think age related type 2 diabetes. The interesting thing about a high fat, low carb, diet is that in many ways is circumvents the glucose metabolism system in older adults, relying rather on ketosis for energy needs.
