the previous post past times introducing the stance of using exogenous ketones for improving the signs too symptoms of Alzheimer’s, piece non requiring the afflicted private to brand any dietary changes. (Recall that, according to researchers, a really depression carb diet is “inconvenient” to prepare too consume.) Is at that topographic point a house for exogenous ketones inwards AD therapy? Yes. I believe at that topographic point is. It depends on the person’s historic catamenia too severity of illness, but I absolutely admit that exogenous ketones tin improve character of life. BUT: with the exception of some really specific cases, which I’ll raise inwards a bit, I cannot back upwards them beingness used equally the sole intervention. It’s equally bad equally telling a type-2 diabetic to exercise insulin and create aught else to influence the way their torso handles glucose, or, really, insulin, itself.
Please enjoin me someone out at that topographic point is on the same page equally me here.
“Alzheimer's illness patients oftentimes undergo changes inwards nutrient preference toward sweet, carbohydrate-rich foods, which would brand compliance to a ketogenic diet difficult.” (Henderson et al., 2009)
Really? Do they undergo changes inwards nutrient preference toward sweet, carbohydrate-rich foods after they develop Alzheimer’s disease, or are refined saccharify addicts to a greater extent than probable to develop AD? Which is the chicken, too which is the Cadbury Crème Egg?
Now, here’s where things teach deep.
Exogenous Ketones: Band-Aid on a Sucking Chest Wound
Let me soil hither inwards no uncertain damage that, for the goal of feeding the neurons of someone whose encephalon is starving to death, I fully back upwards elevating blood ketones past times just nigh whatever agency that essay effective—including administering exogenous ketones.
HOWEVER, it is my hunch (and, equally always, it is just that—a hunch) that the combination of artificially elevated ketones AND those endogenously synthesized via a lower-carb diet and, if possible (based on patient wellness too mobility), exercise too intermittent fasting, would hold upwards a multi-pronged strategy for really teach things improving. (And in all probability to a greater extent than effective, to boot, particularly over the long term.)
I exercise the next employment all the time, because, frankly, I think it genuinely hammers domicile the point: In the absence of dramatic dietary too lifestyle adjustments, administering exogenous ketones is similar bailing H2O out of a leaky boat without stopping to land the hole -- y'all just deal the symptoms piece the rootage causes direct house wreaking havoc.
Giving someone ketones from an exterior source without requiring them to modify at to the lowest degree some of the dietary too lifestyle factors that mightiness hold upwards having a negative conduct on (or dare I come upwards right out too say causal relationship) on progression of AD, is the lazy way out.
For someone who’s ninety years old, severely demented, too is non probable to all of a precipitous surrender their morn oatmeal inwards favor of eggs cooked inwards kokosnoot oil, too thus yes, absolutely, let’s dose ‘em alongside a ketone drinkable too allow them alive their in conclusion few years alongside ameliorate command of their faculties.
But AD too its precursor—mild cognitive impairment—are striking people ever younger. So for someone inwards their slowly 50s or mid-60s—who mightiness direct maintain 25-35 to a greater extent than years of life—if that individual doesn’t want to brand whatever changes that mightiness halt things from getting much worse, too they’d prefer to just suck downwardly the ketones along alongside their pound cake too apple tree juice, too thus fine. But score my words: people who accept ketones too don’t seat travail toward correcting potentially causative too exacerbating behaviors volition direct house to decline. (To stick alongside my before analogy, they haven’t patched the hole; they’re just bailing.) And equally they create decline, they volition probable require higher too higher doses of ketones and/or to a greater extent than frequent dosing. (Kind of similar diabetics who don’t modify their diets, too destination upwards requiring ever to a greater extent than insulin, at ever higher doses, too typically sense a progressive sh*tstorm of ever-escalating wellness consequences, since they direct maintain done precisely nothing else to modify their situation.)
Let’s remember: before the synthesis of injectable insulin, diabetics had to reduce their saccharide consumption. It was pretty much the solely way to forestall blood glucose from going sky-high. Same bargain alongside some forms of epilepsy: before the advent of anticonvulsant drugs, a ketogenic diet was the only way to bring down seizures. (Even now, inwards the grand historic catamenia of fancy pharmaceuticals, people alongside “intractable” epilepsy still direct maintain to follow a KD for seizure management.)
And before the creation of exogenous ketone preparations, at that topographic point was one way to get upwards ketones: dietary manipulation. (Be that via starvation, diverse permutations of fasting, or a really low-carb diet.)
Like I said, I think exogenous ketones do direct maintain a house inwards the handling of AD, peculiarly for people of really advanced historic catamenia or really severe illness state. BUT, the younger someone is, the to a greater extent than probable their bodies volition hold upwards able to adjust too response to diet & lifestyle changes. Giving high doses of ketones is similar applying a tourniquet to a serious haemorrhage wound. Yes, y'all ask that immediate criterion to deal the shrewd crisis. But y'all don’t stop alongside the tourniquet too create no other treatment. You teach the injured individual to the hospital, pronto, where they tin genuinely fix the problem. So yes, give the ketones, WHILE YOU ALSO address the underlying issueS.
Ketogenic versus depression carb:
Is bigger e'er better?
Okay. Last time, I made a distinction betwixt a ketogenic diet (KD) too a low-carb (LC) diet. I volition write to a greater extent than nigh this inwards a split post soon, but for now, let’s just admit that a medical intervention-type ketogenic diet, which is sometimes prescribed at a ratio of 3:1 or 4:1 (that is, three or iv parts fatty to 1 constituent combined saccharide too protein), mightiness non hold upwards required to improve cognitive constituent inwards AD.
Here’s the thing: a garden-variety LC diet tin hold upwards considered “ketogenic” inwards that the torso volition generate to a greater extent than ketones than it does on a higher carb diet, fifty-fifty if someone isn’t deliberately chasing super-high ketone concentrations on their blood meter. My hunch is that the double-whammy, one-two punch, if y'all will, for AD, would come upwards from dietary & lifestyle changes AND the ketone esters. (And if we're talking nigh mild cognitive impairment, equally opposed to really advanced AD, a VLC diet mightiness non fifty-fifty hold upwards necessary. For some people, just going lowER carb mightiness hold upwards plenty – just plenty to bring down insulin resistance, too possibly combine that alongside ameliorate sleep, to a greater extent than physical activity, daylight, fourth dimension outdoors, stress reduction, etc.)
‘Cuz here’s the other thing I’ve been thinking about:
It’s non just the ketone levels inwards the blood. It’s what the torso is DOING alongside them.
See, blood ketone levels of 1.0 or 1.5mM mightiness hold upwards considered “low” if you’re specifically looking to teach that grade upwards inwards the 3-5mM neighborhood. But 1.0 or 1.5mM is all the same ten times the “normal” grade of someone consuming a diet of “balanced” macronutrients. And possibly some people do require levels of 3-5mM, but I suspect others volition create just fine at 1.0-1.5mM. And I suspect that people who do just fine at these levels would hold upwards the ones who direct maintain adjusted their diets too lifestyles such that their bodies direct maintain ramped upwards the enzymatic too biochemical mechanisms to USE the ketones.
When nosotros withdraw heed verbalize of “keto-adaptation,” it’s commonly inwards discussions nigh athletic performance, but it likewise applies to everyday folks not doing Ironman triathlons too Tough-Mudder-Spartan-Century-cycle-athlons. And if it takes a few weeks for young, healthy, physically active people to fuel themselves adequately alongside ketones, what does that say nigh middle-aged too elderly people, who mightiness direct maintain the added challenges of metabolic syndrome, sarcopenia, decreased liver function, express mobility, etc.? Why would nosotros automatically assume these people tin brand fabulously efficient use of a large dose of exogenous ketones, when they’ve done aught to ramp upwards those pathways?
The studies to appointment on the exercise of exogenous ketones present that they are, inwards fact, effective for improving cognition, but how much more effective mightiness they hold upwards in combination alongside a low-carb diet, intermittent fasting, exercise, to a greater extent than sleep, too all the other factors that mightiness teach those pathways firing on all cylinders too assist ameliorate insulin resistance—which is i of the principal drivers of AD?
I just think that when nosotros depend on exterior ketones—or, really, fifty-fifty when someone’s on a LC diet—if nosotros focus obsessively on the blood ketone levels, nosotros accept our focus off the actual problem: impaired cognitive function. I worry that caregivers volition chase numbers inwards a potentially misguided essay to teach ketones equally high equally possible. (Within healthy physiological parameters, of course. Please know that when I say “as high equally possible,” I am not referring diabetic ketoacidosis-type levels.)
The guiding component should non necessarily hold upwards high levels of β-OHB, but rather, how the AD patient functions. For epilepsy, for cancer, too for a few other conditions, ketone too blood glucose levels mightiness thing to a greater extent than than they create for AD. You don’t ask a blood or breath ketone meter to enjoin y'all your loved one’s retentiveness is working better, or that they’re to a greater extent than similar their “old self” when interacting alongside people, too they haven’t had whatever [or direct maintain had fewer] uncharacteristic behavioral outbursts. Numbers are a GUIDE. Higher mightiness non necessarily hateful better. It might. But nosotros don’t know for sure. Again, the enquiry isn’t how high the ketones are, but how good the individual is using them.
So, measurement blood levels of β-OHB genuinely solely gives us a surrogate indicator. The levels of B-OHB inwards someone's blood tells us aught nigh how effectively someone's cells are genuinely using those ketones.
