Paul Saladino has been saying this for over 5 years but people ignore him because he's often shirtless and eats lots of protein.

A broken clock is right two times a day.

A stopped clock is right twice a day. A broken clock could potentially never be right, like if it's perpetually 10 minutes behind.

Paul Saladino says a lot of things. Which of his claims are you specifically referencing here?

About fat accumulation and decades of chronic inflammation in the brain being huge factors for Alzheimer's.

Be careful interpreting this study summary. The article's peer reviews (on PubPeer) list a few analytic issues that call the findings into question: https://pubpeer.com/publications/59F515775D10D854ABB7F4B31D4...

Hrmmmmm the controls for the first 2 graphs appear to be the same and they're called out for it [0].

But it could very well be that they're supposed to be the same? Authors may just need to better highlight why the same control is allowed to be use for comparing 2 different result sets.

So, is this why fasting sometimes seems like a solution? Edit: Oversimplified, but: Less, calories, less fat? Excess calories, more fat?

Fasting seems like a solution because in the fasted state your body doesn't need to produce insulin. Your body needs insulin to push fat into cells. Your pancreas gets a break, and perhaps sensitivity improves when you go on an extended insulin-free holiday.

Doesn't this boost the hypothesis that Alzheimer's is closely related to insulin resistance in the brain? What some people call type III diabetes. I ask because one of the hallmarks of insulin resistance is the presence of lipid droplets in close proximity to mitochondria [0]. [0] https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10455923/

Plausible. I think this was also addressed in the work of Christopher Palmer.

If it does boost that hypothesis, what then? Are there things you can do aside from the basic focus on diet, exercise, and sleep?

Highly recommend. I think is what you are looking for.

Paul Saladino has been saying that APOE4/4 is linked to damaging lipid droplets in Alzheimer’s disease microglia?

Earlier quoted context omitted.

There's a really interesting paradox where, compared to healthy adults, intramuscular lipid droplet storage near mitochondria is increased in: 1) People with obesity 2) People with type 2 diabetes 3) People who do endurance exercise Even though #3 is highly protective against #1 and #2. The best explanation I've seen is that the important difference is why the lipid droplets are being deposited [1] [1] https://link.s…

If I am rich enough to have a down payment for a Bay Area house I’ll be tremendously in debt. But that wouldn’t put me in the same boat as someone with oodles of credit card debt. I’m guessing in endurance athletes it’s there because it’s about to be used. In the obese it’s there because they’re running out of places to put fat.

Right - but even then, if a super fit endurance athlete stops exercising, they don't immediately become diabetic. The upstream cause (what biochemical stimulus is driving the fat deposition?) is probably where the key insight lies.

GLP1 analogs could help. They can cross the blood–brain barrier and stimulate the GLP1 receptor in the brain.[1]

There is also research showing improvement in Alzheimer's disease symptoms. [2]

As a former Alzheimer's researcher, this is a big fucking deal. It puts together a lot of clues (APOE risk, microglia) and finds a theory that makes a lot of sense. All around the world, there are labs pulling late nights trying to figure out how to drug this.

What kind of fat is it? Like is it possible to avoid by avoiding too much fat?
