“you have a critical energy gap that you need to change you need to address that Gap and the best way to do it of course is with ketosis”
Ketosis (and ketones) is the best way to address the critical energy gap in the brain associated with Alzheimer's disease.

“typically we don't recommend for example coconut oil MCT oil we recommend if you want to take some want to get into ketosis exogenously just take some exogenous Ketone take Ketone salts take Ketone Esters those sorts of things you can do that a couple of times a day and get nice spikes in your Ketone levels”
For individuals who are APOE4 positive, MCT oil and coconut oil are not recommended; instead, exogenous ketone salts or ketone esters are recommended to achieve ketosis, taken a couple of times a day for nice spikes in ketone levels.
“we encourage people to measure their ketones whether you like to do it by finger stick or you can do it by breathalizer to get in the appropriate Ketone range”
Patients are encouraged to measure their ketones (via finger stick or breathalyzer) to confirm they are in the appropriate ketone range.
“because getting into ketosis is so critical for supporting brain energetics we tell them just start by taking some exogenous ketones do it for a couple of months no problem because we need to get that energy up”
Taking exogenous ketones as a supplement for a couple of months can support brain energetics, particularly for those who find it difficult to achieve ketosis through diet alone (e.g., vegans or vegetarians).

“Steven canine showed years ago you can ramp those ketones up to 1 two three Millar beta hydroxy butyrate and you can you can address that energy gap”
Research by Steven Cunnane showed that ramping ketones up to 1–2–3 mM beta-hydroxybutyrate can address the brain's critical energy gap seen in Alzheimer's disease.

“in 2021, a randomized trial testing the effects of a ketone on adults with obesity showed improved processing speed, improved working memory, and more blood flow in the brain, which is increasingly important as you get older.”
A 2021 randomized trial found that a ketone given to adults with obesity improved processing speed, working memory, and brain blood flow.
“a study from 2022 where researchers gave participants ketone monoesters before a soccer match and measured their reaction time and other aspects of cognitive performance.”
A 2022 study found that giving participants ketone monoesters before a soccer match improved reaction time and other aspects of cognitive performance.
“In 2012, for example, the first study of its kind showed that consuming an exogenous ketone raises blood beta hydroxybutyrate levels to that typically seen during a long fast or a ketogenic diet.”
A 2012 study showed that consuming an exogenous ketone raises blood beta-hydroxybutyrate levels to those typically seen during a long fast or ketogenic diet.
“a 2025 randomized placebo-controlled trial tested Ketone IQ in healthy college-age adults. They performed 10-second sprints on stationary bikes. Each participant consumed half a gram of R-1,3-butanediol per kilogram of body weight per day for a week. Amazingly, Ketone IQ improved peak power by 10% and average power by 16%”
A 2025 randomized placebo-controlled trial found that Ketone IQ (R-1,3-butanediol) at 0.5 grams per kilogram of body weight per day for one week improved peak power by 10% and average power by 16% in healthy college-age adults performing sprint exercises.
“a study published in Alzheimer's and dementia asked what fuel can the aging brain still use. As cognitive impairment progressed, the researchers found that the brain became less able to use glucose, its usual fuel. And what actually happened was that ketone uptake remained relatively preserved. That's really important because it suggests that even when the aging brain struggles to use sugar for energy, it can probably still use ketones as the alternative fuel.”
A 2018 study published in Alzheimer's and Dementia found that as cognitive impairment progressed, the brain became less able to use glucose but ketone uptake remained relatively preserved, suggesting the aging brain may still use ketones as an alternative fuel even when it struggles to use glucose.
“the third area is energetics and that's oxygenation blood flow mitochondria and ketones the ability to have a substrate to burn”
Ketones are one of four critical areas for brain energetics, serving as a substrate the brain can burn.
“sugar damages your ability to support your synapsis so you got to address with ketones you got to address the energy you've got to address the insulin sensitivity”
Sugar damages the ability to support synapses, so ketones must be used to address brain energy in Alzheimer's.
“when we used to grow the neurons basically using a ketogenic diet you can increase the way the brain uses energy and make it basically have more energy by feeding it fat instead of sugar and carbs”
Feeding the brain fat instead of sugar and carbs via a ketogenic diet can increase brain energy utilization and give it more energy.
“Ketone IQ is a drink whose active ingredient is a ketone precursor called R13 butin dial. Now you don't have to remember that. What's interesting is that your liver converts the drink into beta hydroxybutyrate which your brain and your muscle can use for energy.”
Ketone IQ's active ingredient is a ketone precursor (R-1,3-butanediol) that the liver converts into beta-hydroxybutyrate, which the brain and muscles can use for energy.

“when you have cognitive decline you've lost both of those so you are literally starving your brain you've lost the glucose because you now have insulin resistance you've lost the ketones because your insulin is high and it's preventing you from making the ketones”
In cognitive decline, the brain loses the ability to burn both glucose and ketones, effectively starving the brain; high insulin levels prevent endogenous ketone production.
“by cutting back on carbohydrates, what you're actually doing is flipping a switch that tells your body to start producing these molecules as an alternative energy source besides glucose.”

Sinclair expresses interest in measuring ketone levels continuously via a wearable device.
“I've long been interested in how fasting may affect brain health. And you've likely heard of ketones in the context of the ketogenic diet or in fasting.”
